DST dedicated server build 232355 OSX:
$ lsof -np $(pgrep -d , dont) -a -i6 <sound of crickets>
Are there any plans to make DST IPv6-capable (in any capacity)? I know Steam is one of the bad apps who don't do IPv6, but small steps in that direction should still be possible for DST, eg. allowing players to connect to offline servers (AFAICT, no steam connection is needed there).
Disclaimer: I've helped with setting up a NAT64 test network at work, and having been in the IPv6 echo chamber + having tried some of the things I normally use in such environment, I did notice quite a few things are broken (recent stats say 15% of apps don't work correctly), so I set up an "effectively-similar" setup at home to try things out and pester developers for support.
If you need help with setting up a small NAT64 network for testing, or with testing any early builds with IPv6 support, I'm eager to help.
Launch dedicated server. Inspect the process' list of open network files (sockets, etc) and check if it's listening on UDP6.
