Let me confirm, do you mean the bitstring vs nibble format by the "proven format", or does it include the upper domain (i.e. ip6.int. vs ip6.arpa.)? Anyway, through the responses so far, I feel we must definitely move to ip6.arpa. (regardless of the bitstring vs nibble issue). The migration should cause additional pain to deploy IPv6, but, with the reality, we should start the migration now... JINMEI, Tatuya Communication Platform Lab.

Subject: reverse delegation under ip6.arpa.?Hello, recently I was very surprised, when I found that there is an existing ip6.arpa. domain, where the reverse IPv6 nibble format is delegated to the registries. I found no mail or announcement anywhere that from now on ip6.arpa should be used for the reverse nibble format. Is that a fact, or is ip6.arpa just a global testing scenario that is confusing me? I know that ip6.arpa should be used instead of ip6.int for political reasons, but I always expected to stay the nibble format in ip6.int and the bit-string labels to appear in ip6.arpa someday. Well, ok, now that the bit-string labels are to be changed to experimental, that might be not possible anymore. But I'm not sure if it such a good idea to just change the zones. Right now there is a well established and well working tree under ip6.int. If there will grow a second tree under ip6.arpa now, things might become very confusing. As a resolver, I don't know if I have to lookup the name for my IPv6 address starting with .arpa or starting .int. If I lookup in the wrong tree, I might get no answer, while the correct one is in the other tree. Yes, I could lookup in both trees, but if the answers differ, which one is the correct one? Is there a solution for this? What is the current policy? Maybe I am confused because I missed something?
