There's a lot more of this thread, but I thought that this message was particularly relevant for our work here in this WG.

Thanks,

Most of the renumbering issues that remain are outside of the perview
of the IETF.  Hosts have had the ability to securely register
themselves in the DNS for a decade now.  Microsoft AD has hosts
register themselves using these mechanisms.  DHCP handles both
static and dynamic addresses.  Now we may want a way for a host to
register itself securely with the firewall.  That way when a host's
IP address changes the firewall gets updated.

Most of the renumber problem in people refusing to get out of the
way of automation.
