The IPv6 internet connection testing preparations for major ISPs and network providers frequently appeared on the IPv6 Internet Day of the past June, perhaps not surprising at all. Unexpectedly, Blizzard Entertainment, the publisher of the popular massively multiplayer online role-playing game (MMORPG) World of Warcraft (WOW), took the lead in supporting IPv6.
For World of Warcraft players, with the release of the patch for World of Warcraft 4.1, using the IPv6 protocol is now available. Of course, before using it, players must also have IPv6 connections. According to an employee from Blizzard, if IPv6 Internet connections are not enabled, the related IPv6 connection options will become grayed out, resulting in unavailability.
To run world of warcraft on an IPv6 network, you must use pure IPv6. 6To4 is a dynamic tunnel mode that can use IPv4 unicast to pass through the IPv4 internet, while Teredo is another type of tunnel technology, you can use User Datagram Protocol (UDP) data packets based on IPv4 protocol to send IPv6 data packets.
To do this, of course, in addition to IPv6 Internet connections, you also need to ensure that the hardware of the home network also supports the IPv6 protocol. Unfortunately, most SOHO/consumer-level network devices do not support IPv6.
For World of Warcraft players who are mainly interested in playing games, this choice has no practical significance. Selecting IPv6 does not bring any additional benefits. Really angry!
However, I estimate that due to the small number of IPv6 protocol users, there may be faster network speeds and more stable transmission. Blizzard provides IPv6 support for World of Warcraft. The real focus is to ensure that all players and game servers are ready for the full deployment of IPv6 protocol.
