Indeed not. We currently have to maintain a large and complex distributed registry of ipv4 ptr patterns which are meaningless and must therefore be filtered out before making policy decisions about the presence/absence and match/doesn't of a ptr record and it's associated a record. V6 should attempt to be better than v4 in this regard. In fact v4 should attempt to improve in this regard. Functional at high cost and risking complexity collapse every day and twice on Sunday is not a status quo to love, not to copy from v4 to v6. Vixie -- Sent from my Android device with K-9 Mail.
