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.
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 think what you'd be doing is giving anybody you have assigned an IPv6 address to the ability to update the PTR (or a delegation, since Mark suggested that too) for that particular address. So, it's not "my reverse delegation", it's "my 2^80 or fewer reverse delegations" (if you've been assigned a /48). Joe
