Dynamic DNS

[Kevin Darcy]

To provide redundancy for a zone to the world in general, practically speaking a slave must have a statically-assigned address. If you were to use a
registered slave with a dynamically-assigned address, it would not only harm your redundancy, but also your security, since if someone were to get the
former address of your nameserver assigned to their server before all of the old A records expired from everyone's caches, they could conceivably hijack
your domain temporarily. Do you implicitly trust *everyone* in your dynamic address pool?
