Would you see the querying application informing you of intent via option code saying "If I'm unable to talk to you once TTL expires, I may serve your last known good answer"? What would a server then do if this intent were known? serve some alternate data, or even return REFUSED? I could see sending a secure notify to anyone who requested the QNAME after change, but holding this state may end up with complexity similar to what's some have seen with ECS. - Jared -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
