@waxen scroll that cable stripper works with cat6a?

little schooner Mar 8, 2019, 7:36 PM

#

@rocky badge Is it correct to connect to a server like this: https://machine.my.domain.com

#

if I want the certificate https to not throw an error in web browser?

#

It can't be like https://machine?

waxen scroll Mar 8, 2019, 7:50 PM

#

it cant

#

need FQDN

#

actually

#

you need FQDN and it needs to be signed by a well known company

#

if you self sign it will still error

little schooner Mar 8, 2019, 7:53 PM

#

I see. Just checking because I am rolling out a CA at home

#

but wanted to make sure I was doing it right when issuing by fqdn

waxen scroll Mar 8, 2019, 7:53 PM

#

if you roll out a CA and all of your systems were told the trust that CA, it shouldnt error

little schooner Mar 8, 2019, 7:54 PM

#

Yes, it only errors if I dont add the domain part of it

#

with it, it seems to accept it

#

Is this good?

encryption isnt my strong point, so IDK... theres a bunch of options that can be enabled and disabled... some of them being less secure

i forgot what the options were called ;/

https://en.wikipedia.org/wiki/Cipher_suite

Cipher suite

A cipher suite is a set of algorithms that help secure a network connection that uses Transport Layer Security (TLS) or its now-deprecated predecessor Secure Socket Layer (SSL). The set of algorithms that cipher suites usually contain include: a key exchange algorithm, a bulk...

thats what they're called

I use Ubiquity M5 300 and 400 for now cause of the price and availability. Anyways i get full transfer rate of 300/300mbps on distance of 1,4km both setted up at feeding 3dB +20dB and getting perfect signal -52dB also AirMax is always 100%. And because of not so much 5GHz signal beign in the area i got bout -107dB noise. The price is cheaper than Nanostation.

#

Right now i get free internet from a local coffee/bar place. Still using a VDSL+2 but the modem provided by ISP is trash. So i just use that one to bypass the telephone line to LAN. And i dig out from spare parts a pc that runs PFSense as my powerfull router. With a Core 2 Duo E7500 and 4GB Ram it's a Dell Optiplex (with Wake on Lan). For local wifi i use Ubiquity Lite AP. So by far i get no like problems of internet speed goin low, internet restarting and etc.. Now i'm just waiting when they gonna have here in town Fiber Optics.

hello people, I've seen a lot of people making mentions of a "free" Meraki Cisco switch... do you guys have any clues?

clear igloo Mar 9, 2019, 12:01 PM

#

You attend a training for a day or something and they give you a switch with a 1 or 3 year license (I forget)

pale sphinx Mar 9, 2019, 12:34 PM

Hello

#

I Bought this switch with webpanel recently. Ive had hardtime to get it working.
Ive got it working now but my log spams WAN to 230.0.0.1:6666 is this normal?

thick minnow Mar 10, 2019, 6:11 AM

#

would you guys go with pfsense or opnsense or...something else? I'm kinda undecided because I'm replacing an old cisco router and the new kids are powerful. I also hear some things about untangle and Sophos utm but those seem more like consumer based. I'm looking for something to replace my setup. (Also I wanted to point out I was asking from a wisp pov. I have to change some secure isp stuff but that's for another day)

#

well, that's a long text

little schooner Mar 10, 2019, 6:53 AM

#

I was thinking of moving to a pfsense box. The features I was most interested in were the pfblocker that's easy to configure and openvpn, also easy.

#

the name is familiar and I am familiar with it and meets my needs

#

I do not do layer 7 inspection

harsh jewel Mar 10, 2019, 7:01 AM

Im having trouble ive already had someone help me to a extent its not my firewall and my isp doesnt block ports it has to be a router/network issue

Anyone got suggestions for a server config to run a discord bot for around 40 servers, approx 22k users?

pseudo blade Mar 10, 2019, 2:17 PM

#

What does it run on now and what's the bottleneck?

languid aspen Mar 10, 2019, 2:32 PM

#

What does the bot do? I run a bot on my server and it has about 10k users. It does music and other things. But from what I gathered, one music session uses about 0.5% CPU, so if there is 40 servers you should not run into a CPU bottleneck. As long as you have about 4 cores and a good clock speed you should be fine. No need for expensive server grade stuff. Storage highly depends on what bot you have, I have had my bot running for about a month and only stored 7mb of data, so nothing more then a 120gb hard drive (with redundancy of course) will be needed. The issue is network bandwidth. You receive everything that goes on in each server so if you have a large amount of updates in that server, you will run into a bandwidth issue. Right now I'm using about 400kB to 600kB a second and when playing music, 120kB per server using the music and 1.5mB down per server. So I would recommend a good internet connection. Also, discord API has a tendency to kick your bot off their network now and again. Make sure it auto restarts otherwise your bot will go down without warning. @drowsy wolf

little schooner Mar 10, 2019, 2:53 PM

#

@thick minnow wait for next version of pfsense for gui improvement

drowsy wolf Mar 10, 2019, 3:28 PM

#

I manage a datacentre with unlimited bandwidth, I'm asking just for hardware side but that answers most my questions.

#

I might just use a Ryzen 2600X, Samsung 970 Pro 1tb m2, 32gb ram should be enough, but I'll use 2 16gb sticks so I can top up if I need to.

#

The bot is made to hook into our services for my company discord

#

So in general it'll include CDN upload and viewing of files, github stuffs, links to our facility management panel, but also general purpose stuff like music, VC tools, punishment stuff, etc

#

We've got an incredibly fast rack of database nodes so I don't need to worry about SQL or Redis but I just want the bot to run reliably

pseudo blade Mar 10, 2019, 3:49 PM

#

I doubt you'd need anything a tenth as impressive as that.

#

Naturally it'll depend on how you implement your stuff.

#

For reference we've got a box handling moderation for 20k users on 9 servers using less than 1GB RAM on NodeJS, with it caching all messages.

drowsy wolf Mar 10, 2019, 3:53 PM

#

All of our software components are custom and we only include what we need so integration should be pretty neat

pseudo blade Mar 10, 2019, 3:53 PM

#

What language will the bot be written in?

drowsy wolf Mar 10, 2019, 3:55 PM

#

The bot probably discord.js and its easy to implement interactions between bot and software via js anyway

pseudo blade Mar 10, 2019, 3:56 PM

#

Just don't do anything stupid (i.e slow, blocking stuff) and it will likely be fine on basically anything.

drowsy wolf Mar 10, 2019, 3:58 PM

#

Was the specs I listed overkill?

#

It's purely because we've got those components spare already half built

pseudo blade Mar 10, 2019, 4:02 PM

#

So obviously the library doesn't need much of anything - It depends on what you're making it do - But based on what you're saying it does sound like overkill.

#

I know of a Python bot that scaled to 5k servers on 1GB RAM and a single CPU core, doing moderation stuff and code execution via stored database values.

#

Actually ran in Virtualbox until it was recently moved to a Docker container.

drowsy wolf Mar 10, 2019, 4:50 PM

#

I'll probably just install that system in general and then run multiple things on there

#

It may end up being that I use it to host the bot in a docker container and then shift the admin panel onto there

stoic tendon Mar 10, 2019, 6:00 PM

#

Actually, how are some websites blocked on the network? Router settings or a dns which blocks certain websites

clear igloo Mar 10, 2019, 6:02 PM

#

DNS blocks and usually most common but you can do IP blocks or deep packet inspection as well

stoic tendon Mar 10, 2019, 6:03 PM

#

Like, ive seen some netowrks where you cant rly access certain webites

clear igloo Mar 10, 2019, 6:06 PM

#

All depends on the network, you can filter everything through a proxy as well and block that way too. There isn't a 100% guaranteed way to block everything without doing a whitelist only model

stoic tendon Mar 10, 2019, 6:07 PM

#

Like, the network i saw had blocked social media

#

Facebook, instagram, or whatever

thick minnow Mar 10, 2019, 6:08 PM

#

most networks that block sites relie on a proxy that has the blacklist (or whitelist) in it to do the job

clear igloo Mar 10, 2019, 6:08 PM

#

I mean I can block social media with a couple clicks via DNS blocking, that's easy

thick minnow Mar 10, 2019, 6:09 PM

#

and they can set anything based on category of site or specific domains or both

stoic tendon Mar 10, 2019, 6:09 PM

#

Id like to knwo how to do it

#

Know*

#

But, how do you block usage of social medua apps on mobile? Or block them by ip?

thick minnow Mar 10, 2019, 6:10 PM

#

even the apps use dns

stoic tendon Mar 10, 2019, 6:11 PM

#

So, you just block their dns?

clear igloo Mar 10, 2019, 6:11 PM

#

I use OpenDNS Umbrella but most home users would usually have a setting in their router to block specific stuff which does about the same thing

thick minnow Mar 10, 2019, 6:12 PM

#

yeah, if you block all the domains they use, itll make site and app not avail

stoic tendon Mar 10, 2019, 6:13 PM

#

Alr, ty

clear igloo Mar 10, 2019, 6:15 PM

#

Umbrella gives me more control and insight into the network whereas a typical home router might just have a "block social media" button. I can see the requests being made to every site, potential malware, command and control, etc. requests as well and filter by about 100 different categories and risk levels. There is a home version for $20/year if you want to mess around with some filtering and whatnot for fun, doesn't give the level of detail as the enterprise version but it's still nice

harsh jewel Mar 10, 2019, 6:16 PM

I’m having trouble port forwarding I’m trying to make a server for a game I play called five m I have it open so it is listening to my port I even have a app called listen to test if your router is port forwarding right nothing shows up when I try to port forward it won’t open I’ve talked to my isp they do not block ports any help please

#

@waxen scroll Oh, in our case, his lab is not supported by the IT department. He basically calls all the shots because he is a good grant writer

#

IT wanted nothing to do with it because it didn't match the school's computer use policy

#

So they said if you build it and use it with your students, don't come running to us for support

#

and he loved the idea and converted it to a Linux lab

#

I didn't know Cisco gave discounts on switches that massive for education environments. But he was looking for switches and when he saw the price tag, anything over a grand was expensive to him

Not sure if this is the right place to ask, ask in the right channel

#

But

#

I've got a bit of a problem and my solution involves setting up a proxy

#

Problem: school blocked discord

#

Solution: make a proxy

#

However, I want to make the proxy on my RPi at home. I know of a way to make a simple proxy that works on a browser like Firefox

#

However a system wide proxy is preferred

#

The client system, aka me, is running mac

#

Sorry if this is a stupid question

languid aspen Mar 11, 2019, 12:42 PM

#

If anyone could help me with allowing PIVPN clients access to my SMB share that's on the same network please @ me.

waxen scroll Mar 11, 2019, 1:52 PM

#

a system wide proxy is called a vpn

#

so if its a school computer it likely wont work

#

for web, you want to self host https://www.jmarshall.com/tools/cgiproxy/

#

there are many public cgi proxies but many school filters are very good at blocking them since they've been around a while

thick minnow Mar 11, 2019, 2:20 PM

#

If a school blocks something, it’s for a reason.

#

It’s because they don’t want kids shitposting on Discord when they should be learning.

pseudo blade Mar 11, 2019, 2:31 PM

#

Meh. I used to use TOR at school to access perfectly reasonable stuff they had blocked.

#

Worked well enough.

#

Their filters were a bit too overbearing and sometimes stuff required for classes was blocked.

#

Technical college I went to afterwards blocked TOR, but otherwise basically only blocked NSFW stuff and non-[443,80] traffic, so the filter was frankly more useful than annoying unless I needed SSH.

#

Mobile broadband and SSTP were more than adequate for that.

vpn packets are pretty easy are easier to identify then just https

little schooner Mar 11, 2019, 4:58 PM

plus, they can't control your Discord account, they can't limit what servers you're on

plus, COPPA, and Discord can open an opportunity for cyberbullying, data risk, and shit

thick minnow Mar 12, 2019, 12:43 AM

#

I still stand by my original statement @turbid skiff.

You can do whatever you want it’s your life, not mine.

#

Also the fact that you want to use a proxy to bypass the fact that the school IT network administrators blocked certain resources and stuff from the network already makes me suspicious of you.

Innocent legitimate people generally have no reason to want to use a proxy to access restricted network resources unless you want to do that for nefarious purposes or just to “break the rules”. OR if you live in a country that sensors your internet access(Which I highly doubt that you are.)

Yet I’m the “ignorant” one here, ok.

kek

#

I stand by this statement as well.

winged hound Mar 12, 2019, 12:59 AM

Getting caught bypassing network restrictions is a great way to lose all network access.

Honestly if a school IT guy is worried about a student downloading something like wannacry and not being able to fix it, or have things in place to not be affected by It, I'd be suggesting to him to find a new job.

swift fractal Mar 12, 2019, 2:00 AM

#

The key words are getting caught

#

My HS’s IT coordinator left a plaintext master password on one of their servers in a network share. Should have I been snooping? No. Was it worth it for near unrestricted access? Maybe, but I have no interest in other people’s stuff

Last time I checked that powershell script is still there

Or, go the complete other direction.
Walk in the IT office, ask to talk with the lead/head IT guy.
Say you're wanting to get a job as a penetration tester, and if they'd allow you, can you do as much havok as you're able to, to test their network.
Emphasize that's your ideal future job, and any experience getting there would be helpful.

Literally got my first job of 4 years like that.

turbid skiff Mar 12, 2019, 8:01 AM

#

if youre that worried about me getting caught, well...
The IT guy left the password to the teacher wifi on a paper in some classroom where some of my friends copied it. They use it to this day.
During LAN parties that the school organizes all restrictions are lifted, and I mean ALL of them.
We will just have to use discord on mobile in that case. Or use skype if it allows file

And if about the ignorant part: you instantly thought that I'm suspicious when the only thing I wanted to do is have access to discord again. I understand the concern, and it's great that you care, however not everyone is trying to do shitty stuff. I'm in Sweden, so no, nothing is restricted by the state (except for tpb or something? That was a while ago)

#

Well. thanks for the help in any case. I remember setting up a VPN on my pi when I went to the UAE so I'll try reviving that. Also will ask the IT guy today.

@thick minnow Just connect the ports, most consumer switches are dumb L2 switches so any port can be internet or host connected, doesn't matter

thick minnow Mar 12, 2019, 3:25 PM

I was talking about an Ethernet Splitter that this dude could plug into this range extender.

It would be cheaper than buying a switch.

Simpler as well.

#

@covert ibex basically i got new internet that can do 100mbps but my powerline adapters cant even do 20mbps when they're rated for 500 theoretically. I already resynced them and one of them is directly plugged into my laptop thru ethernet. Im pretty sure my ethernet cables are cat 5e so that shouldn't be an issue right?

#

was built in 2002 so they wiring can

#

cant be that shitty

#

What is the throughput that you're getting?

#

Only reason im running powerline is for my laptop. I get 5g wifi in my room at 90mbs and my phone gets 60 but i dont wanna deal with lag

#

Have you done a speedtest on your local network?

#

is lag on wifi an issue still?

#

with 5ghz bands?

#

@thick minnow yeah

#

advertised 100, 10

#

i get 70-90 on my laptop in my room

#

with 8 upload

#

When you say lag, you mean latency right? What is your average ping in MS?

#

8-15

#

ms

#

im just worried about gaming

#

because my wifi signal is at 2/4 or 3/4

#

That's not bad, what type of hardware are you using for your home network? DSL, Cable Modem, Ethernet?

#

isp provided router/ switchj

#

it does 5ghz and wireless AC

#

Who is your provider?

#

fido/rogers

#

i just switched from bell

#

the bell router didnt have 5ghz wifi

#

im just worried since im on the other side of the house i dont want issues when i need a constant stream of internet

#

for gaming

#

so far, netfilx and shit has been fine

#

its just the signal strength that im worried about, regardless if the speeds I get are really good

#

Hmm, well the best thing to do for gaming would be wired Ethernet connection, however since it seems like you want to use WiFI, you'll probably need to make sure that your wireless AP is situated in the best possible location in your house.

#

Generally more towards the center of the house.

#

which is why i was trying to get my powerline to work properly

#

So you have even converge.

#

i cant run a 50ft long cable

#

my room is over the garage so i get screwed even harder

#

but my router is now in my living room, which makes me gettting signal without a secondary router possible

#

Remember, whenever you use WiFI your speeds are almost always going to be slower then a wired connection.

#

I know the basics of networking, my only issue is my powerline adapters

#

they

#

If you have solid objects, walls, and a large distance to where you are, that will also effect the speed/signal strength you get.

#

Does your laptop have an Ethernet port on it?

#

yup, ive been trying to run a powerline adaptor directly to it

#

What do you mean by powerline adapter?

#

If I were you, I'd just buy a range extender and hook that up to your Gateway/Router with an ethernet cable and have that range extender extend the signal from the Gateway/Router and act as it's own AP that your devices can connect to wirelessly.

#

You could also buy more then one WRE and have them installed in various locations around your residence, and have them all cover your house.

#

Just some food for thought for you.

#

That or just hook up your laptop to your Gateway/Router via a wired 802.11 Ethernet connection.

little schooner Mar 13, 2019, 8:51 PM

#

@thick minnow Powerline adapters are only useful and reliable if you are connecting them to the same circuit

#

if it has to go through the circuit breaker you can pretty much say bye bye to good speed

thick minnow Mar 13, 2019, 8:58 PM

#

@little schooner what are the chances it does if 1 is in the living room and ones is in my bed room?

#

can that explain why im only getting 20/100

#

its been right beside my breaker for 2 years with no packet loss or anything

#

but my old internet was 30 down 10up and it did 20 so

#

is it maxed out by my wiring and i haven't noticed?

#

my house was built in 2002 which is why i doubt its that

#

Cat 5e cables can supply 100mbs correct?

clear igloo Mar 13, 2019, 9:02 PM

#

Cat5e is 1000Mbps

#

Cat5 is 100Mbps over long distances, you might squeeze gigabit out of a very short run

thick minnow Mar 13, 2019, 9:09 PM

#

yeah so im at a loss

#

its either wiring in my house or idek

#

i just ran both of them in the living room with one connected directly to my router and my laptop

#

i only got 45mbps

#

its gotta be my wiring

clear igloo Mar 13, 2019, 9:18 PM

#

It's possible there is interference in the wiring or something isn't properly grounded causing issues

#

With powerline there isn't a guarantee unfortunately and while some of the top of the line new stuff might handle connection hops between circuits much better than those of old it's still a crap shoot as to how well it will work in most instances

thick minnow Mar 13, 2019, 9:23 PM

#

if i still get 70- 90 mbps of speed across my house out of the advertised 100 i get should i be concerned with lag and latency over 5ghz wifi?

#

thats my only concern

#

my ping is still only 7ms

#

so far its been fine

clear igloo Mar 13, 2019, 9:24 PM

#

Depending on the connection into the home, it could vary, but if you're getting 7ms over wifi then I wouldn't worry at all

How’s it going my networking friends?

#

Confusing... I'm hosting a Minecraft server on Google cloud, it binds to one ip but hosts on a different 🤔 🤔

#

So far using mcsrvstat it shows that it's working, haven't been able to test on the actual game

#

Hosting on Google Cloud?

#

I’ve never heard of that before. Is this something new?

#

Or I should say, a newer service by Google?

#

Well the VM instance through Google cloud, found it out from Nemes

#

I assume this is a paid service?

#

They give you $300 free credit so I decided to mess with it

#

cloud.google.com

#

Free credit means what exactly in this sense? Is it like Windows 10 where they want early beta testers to use it for free for a while?

#

Well, not anymore on the Windows 10 stuff.

#

But you get my point.

#

🤷 all I know is when you sign up you get $300 for doing whatever you want

#

As a trial

#

Keyword: Trial.

#

You lose the credit after you use it all or after 12 months

#

Hmm. IDK man, I’ve never in my life as of yet hosted anything on a cloud hosting service.

#

It's similar to AWS I think

#

Im sure they’re better people on here that can help you, blob uses AWS I’m pretty sure.

#

I’m used to hosting a Minecraft server the traditional old fashion way, from my home network. lol

#

Haha

#

Even that has become more difficult now since almost all ISP routers have DHCP on them, so if you want a static public IP for your Minecraft server you’d basically be upgraded to your ISPs business class for clients.

You’d pay more as well.

#

Here in england everything has one ip nothing ever changes (not a networking nerd, so don't know terms for stuff) even though I have a dhcp option on my router 🤷

#

It’s been a long time since I hosted anything so don’t take whatever I say to heart.

#

I have almost zero experience in networking so you'll probably know better than I do

#

I’m not a Networking Nerd yet either. I’m taking a networking class in college this semester.

#

Ah nice

#

So far so good, I have my midterm coming up on the 18th.

#

It’s going to cover chapters 1-5 of the CompTIA Network + N10-007 Course.

#

Don’t worry man, you’ll be fine just ask blob when he gets online he can help you probably.

#

I’m pretty sure it’s ok to tag him and he’ll get back to you.

#

Okay, i think it works either way

Do I just have to change that routing to bridge option to put the modem in bridge mode or there is something else I need to do? Already tried to put bridge in that field and internet stops working

📎 IMG_20190314_174118.jpg

little schooner Mar 14, 2019, 4:55 PM

#

@subtle glen I don't think it can be a bridge if PPP is required.

#

If PPP wasn't required, I'm sure it would of worked fine

subtle glen Mar 14, 2019, 5:02 PM

#

but when you select bridge you are prompted to this

📎 bridge.JPG

#

all the other options disappear

little schooner Mar 14, 2019, 5:07 PM

#

yeah, because PPP needs to route the request to remote server

#

a bridge simply connects two dissimilar medium networks together

#

it has the effect of also being a switch, and forwards the requests to other devices down the line too

#

ie perhaps your own personal router could listen for the PPP request and you set it up there

#

@subtle glen

subtle glen Mar 14, 2019, 5:14 PM

#

i'm a little bit lost. So how do you bridge a router then?

little schooner Mar 14, 2019, 5:15 PM

#

By doing what you showed in your screenshot. You turned the router into a bridge.

#

Therefore, it could no longer do PPP to connect to your isp for internet access

#

people do this if they want to use a separate router usually one that has more functionality

subtle glen Mar 14, 2019, 5:16 PM

#

so i have to set this PPP thing on the edgerouter? (the router in cascade with the isp one)

little schooner Mar 14, 2019, 5:17 PM

#

@subtle glen yes. So the bridge would forward any responses to the EdgeRouter

#

and EdgeRouter will be your real router that forwards traffic out

subtle glen Mar 14, 2019, 5:19 PM

#

PPPoe and PPP are 2 separated things?

little schooner Mar 14, 2019, 5:20 PM

#

PPPoE is for ethernet and the other is dsl/dial up/serial connections if I recall correctly

#

I've never actually set up PPPoE except in a Cisco lab so

#

there might be some info I am missing

subtle glen Mar 14, 2019, 5:23 PM

#

wait hold on, so if i put in here the credentials that are in the ISP modem (the one censored) and copy the MTU and PPPoe ID it should work, right?

in theory yes. copy everything exactly, even if it has vlan id

it just says that PPPoe must be between 0 and 5

the one that says 0 ?

no it's not that. so perhaps it's just a random number of your choice

between 1-5 like connection profiles

little schooner Mar 14, 2019, 7:16 PM

Well that option isn't available when you turn that router into a bridge, so it wouldn't make a difference for EdgeRouter being able to connect via PPPoE

cat 6e

clear igloo Mar 16, 2019, 1:28 PM

There is no Cat6e, it's either Cat6, Cat6a, or Cat5e. Cat6e is a non-official standard

pine panther Mar 16, 2019, 1:28 PM

#

Category 6e
CAT6e is an augmented specification designed to double transmission frequency to 600 MHz. There is no standard for CAT6e that is recognized by TIA like there is for the CAT5e. The 600Mhz rated CAT6e is ICC’s premium offering of CAT6 like most of the bulk cable manufacturers. In addition, CAT6e cable with grounded foil shielding can reach full 10-Gigabit Ethernet speeds without sacrificing the maximum cable length of 100 meters.

#

#

Even next to the router I still get 50mbps

#

Sounds like a wireless issue for sure, you could get a dedicated AP if you want to keep things simple. Something like a Ubiquiti AC or something

thick minnow Mar 16, 2019, 2:39 PM

#

But I don't want access point since coverage is good

#

See how your AP is configured. See what channel it’s broadcasting on, as well as other information like what bands it’s supports and frequency it transmits on.

#

Sometimes tinkering with those may help older/newer devices get a little better WiFi speeds from the AP.

#

What standard is it using?

#

What do you mean? It's using both 2.4ghz and 5ghz on the same network

#

So, you’re using dual band. That’s good. But what WiFi standards does your AP device support?

802.11AC? b/g/n?

#

📎 Screenshot_20190316_150006_com.android.chrome.jpg 📎 Screenshot_20190316_150002_com.android.chrome.jpg

#

I’d recommend maybe not using a mixed type for the 2.4GHz try maybe using 802.11n and see how that works.

#

As for the 5Ghz, you should be fine.

The one thing that was nice about classful networking is that you never needed to specify the subnet mask (and one did not even exist at that time) because There was a specific class A, B, C, D, E space so if you had any arbitrary IP, you would know what class it was and what network it was in. They were not even called subnets, they were just called networks. Like AMPRnet got network 44. Subnets came around when those with class A networks wanted to be able to split up their network into multiple zones for their own internal networks which they called subnetworks or subnets.
Until CIDR came around, subnet masks did not even have to be contiguous. There is no reason to do this but if you wanted too, you could have two networks that operate in what seems to be the same space but one of them only uses IPs that end in odd numbers and one only uses those with the even numbers. There is no reason to do this at all but it is still possible.

Here is my copypasta
"Classful" networking is rarely useful other than for understanding How We Got Here.
Class A,B,C represent the position of the first 0 bit in the address and a corresponding natural netmask. A=1st bit (/8), B=2nd bit (10xxxxxx, /16), and C=3rd bit (110xxxxx, /24).
In RFC1918, a single A (10.0.0.0/8), 16 Bs (172.16.0.0/12), and 256 Cs (192.168.0.0/16) were set aside for private networks. Yes, 192.168.0.0/16 is 256 class Cs, not a single class B because it is within the class C space (the bits start with 110)
IP address classes are no longer relevant, beyond understanding how things were done in the past. Address classes haven't been used for assignment or routing purposes for over 20 years, but the term lives on because it keeps getting undeserved new life in networking classes and training materials.
Classfull address assignment/routing was horribly inefficient for two main reasons, both of which were corrected by a combination of CIDR and VLSM:
Assigning IP networks on byte boundaries (/8, /16, /24) was not granular enough. Even if you needed 257 hosts, you would need an entire class B though you could get two class Cs but routing would be harder because there was no way to specify subnet mask. Even worse, if you only needed 25 hosts, you would have no choice but to get an entire class C waisting over 90% of the space.

#

Classfull routing was starting to bloat routing tables, both inside of and between networks. If a network had a little over 8,000 IPv4 addresses under its control, in the pre-CIDR days, that meant that they or their upstream provider would need to announce routes for 32 individual class Cs assuming that they had no class Bs or As. They had to do this even if the networks were next to each other.
It's fun (and informative about a netgeek's skill)
when they call, say, 72.234.7.0/24 a Class C and you
can say no it's not. Then you see if they can say why.
Take everything you've ever heard about classful networking, throw it
away, and outside of trivia games never think about it again. Network
address classes haven't been a valid part of TCP/IP for more than two
decades now.
I seldom see people actually talking about class {A,B,C,D,E} networks as such. It's almost always a reference to the size ~> netmask ~> prefix of a network.
You can safely say that 72.234.7.0/24 is a Class C /sized/ network. While it happens to be in the (former) Class A IP /range/. But it is most decidedly /not/ a Class A /network/.

I thought it was interesting what someone said in the last email
When I first started working with Cisco products (around 1999) I came upon a router doing NAT for internet access that used a discontiguous mask to determine which address to PAT the hosts against as they were doing some creative load balancing. It worked really well, no matter what part of the 'block' the DHCP server gave inside addresses out to. I was stumped for the longest time trying to figure out what this did.
