This should be merged with 6to4 unless there are two confusing, competing protocols. Or just plain redirect this page to 6to4 Truekonrads ( talk)

There are two different protocols, with different addressing formats and purposes (this one is described by RFC  2529, 6to4 is described by RFC  3056) - although they do use the same IPv6 in IPv4 encapsulation format, so redirecting or merging is probably inappropriate. @alex ( talk) 18:46, 9 February 2010 (UTC) reply
