Actually you just need to *let* the hosts update their own ptr records using UPDATE. People keep saying the PTR records don't mean anything yet still demand really strong authentication for updates of PTR records. TCP is more than a strong enough authenticator to support update from self. You can even delegate the reverse zone when doing or just after a PD. * Accept NS/DNAME updates for the reverse prefix from any address in the delegated address range over TCP. This avoids having a temporatially lame delegation. named already has code to do this for /48's as I coded it to to support 6to4.
This sounded like an excellent idea at first, but then I started thinking: As a home user, would I really want to give anyone with access to my network the right to change my reverse delegation? I don't think so. I am not even sure I would want them all to be able to update the PTR record for the addresses they use. Bjørn
