If you want a PTR for every possible address in your network, or even just every possible address in a single /64 subnet then you are SOL as far as IPv6 is concerned. The only way to do it is to fake it - for example by synthesising responses on the fly. You can't cache the synthesised responses either, that would be inviting a DoS. I said this would be "pointless" because if providing RRs were as simple as synthesising one on request, then the presence of a PTR record would no longer be a meaningful indicator of cluefulness (not that it is now IMHO, but opinions clearly differ on that).As for v6 how popular do you see it getting for mail?Well - at least as popular as IPv4 - eventually :-) Regards, K. -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Karl Auer (kauer () biplane com au <javascript:;>) http://www.biplane.com.au/kauer http://www.biplane.com.au/blog GPG fingerprint: B862 FB15 FE96 4961 BC62 1A40 6239 1208 9865 5F9A Old fingerprint: AE1D 4868 6420 AD9A A698 5251 1699 7B78 4EEE 6017
