Hello!
I have bound multiple SRV records to specific ports leading to a single A record sub-domain.
Depending on which service is actually running at the time, my client application reports connecting to the wrong port, when not specified in the Server Address manually.
My question:```yaml
What is the proper setup for different services to be hosted on alternate ports under the same target (sub)domain, to resolve to whichever service is currently running?

A reverse proxy typically would be. If you're using SRV records make sure your application supports them.

The records lead to the different services fine.
I shall format my prior post a little nicer.
I am wondering if the issue is the client or the server.
nimble totem
Are the SRV records for different applications? Or are you talking about load balancing/failover?

All minecraft servers of differing installations.
One Node.
Each server binds to the same IP, under a different port.
SRV record for each port (same every other argument) is assigned to a single (sub)domain.

I don't know if you can do failover with just SRV records, there doesn't seem like a way to determine which record goes through is implemented there.

I think context with visuals would help more...
These are the Allocations.
They all have the same IP

I don't think what you're trying to do is possible with SRV records. You could use different subdomains.
They each need their own target. There is no method being implemented here to determine where traffic goes. You have one record telling it to go one place, then another record telling it to go another place, etc.

you realize what you've done is make round robin dns for IN SRV _minecraft._tcp.domain.com
frigid lake
yes

Is this for hiding real ip or just load balancing?
sand token
It's to allow me to only have to turn a server off or on depending on the desire...
I though its hiding real ip

Oh having a domain?

Oh having a domain?
Yes like if someone do ping on your domain, its not even real ip like if u re using cloudflare, so when someone ping, only got cloudflare ip
open pier
Is it possible to make it so I only have to use mc.zethal.games?
frigid lake
Yes like if someone do ping on your domain, its not even real ip like if u re us...
wrong actually
SRV records cannot be proxied
open pier
Yeah and Cloudflare only proxies HTTP/S
frigid lake
so when you do dig _minecraft._tcp.domain.com you get the srv target record, which gets looked up (unproxied) to IP [unless you have enterprise with spectrum addon]
nimble totem
And Cloudflare shows you a big warning at the top of your DNS page letting you know the SRV record means your backend is exposed.
