Not wrong but correct. Delegations for that block can be requested by emailing email@example.com But Geoff Huston has already published this draft: http://www.ietf.org/internet-drafts/draft-huston-6to4-reverse-dns-01.txt Which should solve the 6to4 problem. Personally I would say that 6to4 shouldn't be given reverse though, if people require that they are better off getting either native or tunneled IPv6 instead of this transition method especially because of the low deployment of 6to4 relays. > I think this is because 2002: is a test zone. But for me using > it almost always the only way to have reverse mapping is ip6.int. Get yourself a tunneled or native prefix from a LIR closeby. 6to4 is not testing, it is transition and it works(tm).
