WotLK on IPv6

Help and Support Help and Support

Hi everybody,

I’m wondering if the WotLK client is IPv6 capable. It’s difficult to test because the Trinity isn’t supporting IPv6.

However I have good reasons to believe that the client may has IPv6 capabilities.

  • On the login screen is a frame where Blizzard News appears. This frame is definitely IPv6 capable. We modified the client to use a custom web-address. And I can see in my Apache log IPv6 requests from ‘Blizzard Web Client’. It works even with https on Port 443.

  • Entering in the realmlist a IPv6 only domainname and starting the client has success. In the WoW log is only a message LOGIN_STATE_FAILED result: LOGIN_SERVER_DOWN. But this is logical.

  • Blizzard was at the building time of the 3.3.5 client clever enough to use a lot of Microsoft API calls. That’s the reason why the client is even running these days without problems. May they have used a MS network framework that supports IPv4 and IPv6?

What do you think?

Unfortunately, it’s not. It uses socket(AF_INET, SOCK_STREAM, 0); to create its world connection sockets, v4 only
