Why does DayZ not work on IPv6, only on IPv4
Assigned, NormalPublic

Description

Some ISPs have been implementing IPv6 for the past 5 years now because this protocol seems to be a standard. There's been many reports for people not being able to connect to DayZ server after their ISP changed their protocol from IPv4 to IPv6. Can DayZ work on IPv6 as well?

Hello jedi_warrior.
Currently we are aware that only the polish UPC has the issue with IPv6 protocol, we had no reports of other providers having this issue, therefore we believe it is an issue on the providers side. However, we will keep investigating this issue. In case you know of players that have this issue with the IPv6 protocol even with different provider than polish UPC, please tell them to send us the information under this ticket.

Including amra3, it cannot run within the IPV6 protocol, which may be related to Steam itself not supporting IPV6

repro steps

Open and debug the server port, open the IPV6 protocol, and you will receive a dayz that can only play games on the local area network

Germany here. IPv6 only available via provider. Common solution is CGNAT with port adress translation (PAT). Looking for IPv6 server support to sometimes host games with my friends.
