I want to check if the Ipv6 address is present in the subnet.

It will be good if there is a way to check it using some official library otherwise I will have to write the implementation.

I have to do it in Java

Hi there

#

I think In java there is a built-in API called InetAddress.getByName()

#

That can help you in this

I want to validate if the Ipv6 address is present in the prefix

string.contains(":"); pepekek

#

But realistically, check java.net.Inet6Address

#

When using InetAddress.getByName if it's IPV6 it'll return a Inet6Address if it's IPV6

#

i.e.

boolean isIpv6(String addr) {
  return InetAddress.getByName(addr) instanceof Inet6Address;
}```

#

Or something similar

I want to determine if the IP address "21ab:1212:43:d45::" is present in "21ab:1212:43::\48"
