Re: reverse delegation under ip6.arpa.?
well, that RFC has in incorrect statement. It was not IETF consensus, it was IESG/IAB consensus. It is also true that from the last IETF, bitstring (A6) was moved to experimental status, while nibble (AAAA) was retained on the standards track. % >From the RFC 3152: % % > 1.
