Current Behavior

Currently the Panel lists only A-Records as valid in the Panel. But if a host is reachable only via IPv6 and therefore the domain only has an AAAA-Record, the panel ignores it.

Expected Behavior

I would expect that the Panel will also check if AAAA-Records are available.

As an example googles IPv4 and IPv6 only domains:

As you can see only A-Records are accepted.

Steps to Reproduce

Create a DNS Entry that only points to a AAAA-Record. Try to add it as node in Pelican. It will show as invalid.

I think I found the code that is responsible for this:
The Panel uses the gethostbynamel function. This PHP function is known for only supporting IPv4, which is criticized for years. The exact same issue was part of Pterodactyl a few years ago: https://github.com/pterodactyl/panel/pull/4398

  • I have provided all relevant details, including the specific game and Docker images I am using if this issue is related to running a server.
  • I have checked in the Discord server and believe this is a bug with the software, and not a configuration issue with my specific system.

My guess is applying the patch that Ptero used to check for records, over at this commit: 2507845932
