	To test IPv6 in World of Warcraft, you'll need to edit your 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.

Subject: World of Warcraft may begin using IPv6 on Tuesday

For those that don't know, World of Warcraft is currently the largest online
role playing game, with somewhere over 12 million subscribers.

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? :)
