> Can't the router update the DNS?

if the router knows when a new address has been assigned with stateless
autoconf, and if the router knows the "forward name" to be associated with
the address just assigned, and if the router can know a TSIG shared secret
or some other private key that protects the in-addr.arpa or ip6.int PTR's,
then sure.

however, i think we're dealing with a more fundamental problem.  microsoft
avoided something similar by using GSS TSIG.  what's needed is an opaque
and somewhat anonymous and short lived permission blob, that's only useful
for updating one particular thing at one particular time.  TKEY to the
rescue?  donald, are you still listening, and can you chime in?
