More here: http://ipv6.blizzard.com/ To test IPv6 in World of Warcraft, you'll need to edit your config.wtf file and add the following line: SET unlockIPv6 "1" This will activate the IPv6 features. If your computer has a valid IPv6 address, you'll be able to check the "Enable IPv6" checkbox from the Network options in the World of Warcraft client. Once in the game, you'll be able to see which type of connection the client has made to the realms next to the latency information.

Version 4.1 of the game is expected to be released this Tuesday, which will be automatically pushed to all clients. The current Beta version of 4.1 has full IPv6 support. In the beta, it's automatically enabled if you have native IPv6 (non-6to4, non-Teredo). While Blizzard has been pretty silent about this, barring a last minute revert or delay of this patch, there are suddenly going to be a bunch more users that can potentially use IPv6. And these users are the type who are going to be especially sensitive to latency, jitter and packet loss, since this is a real-time game platform. For those of you with Help Desks who have to support users like this, the associated setting in the game's Options menu is apparently called "Enable IPv6 when available". It's apparently grayed out if you do not have IPv6 at all, unchecked by default if you are on 6to4 or Teredo, and checked by default if you are on native v6. The tooltip says: "Enables the use of IPv6, the technology behind the next-generation Internet. Requires IPv6 connectivity to the internet. Checking this box without IPv6 connectivity may prevent you from playing WoW." Anyone from Activision/Blizzard who would like to chime in with more details? :) -- Kevin
