Recently on NANOG I saw the item below, I was thinking about what this actually means. A computer would – similar to DynDNS – register itself and it’s hostname to a DNS server using some kind of authentication. Naturally I immediately thought this was a brilliant plan, and didn’t understand why nobody, with the exception of DynDNS, had thought of this before. The immediate afterthought was that this would be easy to implement with a soft-token, which is the software equivalent of a physical token like RSA’s SecureID, or complicated to implement with PKI infrastructure.

It will be much better when the OS’s just register themselves in
the DNS. Humans shouldn’t have to do this when a machine renumbers.
Named can already authenticate PTR updates based on using TCP and
the source address of the update. For A/AAAA records you setup a
cryptographically strong authentication first.
DynDNS uses username password, which is less secure than the cryptographically strong solution that Mark Andrews mentions below.
