Re: IPv6 and Dynamic DNS

=> it is not a new idea and it should be very close to Jim's tool
(it is why I have written "same kind")... The problem is DHCPv6
is not yet available and perhaps will be a bit expensive then
the AAAA & PTR RRs update service should be provided with
the IPv6 stateless address autoconfig (part of the neighbor discovery).

The proposed context is a rather closed environment with security
constraints and a medium term mobility (ie nomadism). Of course
DHCPv6 is the *solution* but again DHCPv6 is not available.

The proposed mechanism is simple:
 1 - stateless autoconfig user daemon signals addition/deletion of
     global prefixes (including old prefixes at boot time)
 2 - suitable AAAA and PTR RRs are updated
 3 - for security DNS updates are signed with TSIG (using pre-shared keys)

Of course for PTR RR updates this may not work with a random server
but this works inside an organization, even a large one.

PS: the first step is to get a working dynamic update for IPv6,
both in client and server (Jim has already that).
