This assumes that the technology actually exists to easily renumber if
the /48 prefix changes.
The pieces I have not yet seen are:
-- Firewalls -- With IPv4, the firewall rules are built in terms of IP
addresses. Will IPv6 firewalls do something similar or will there be a
single place to specify a prefix?
-- Intrusion Detection & Network monitoring appliances -- is it (or will
it be possible) to specify an IPv6 prefix someplace rather than
embedding the entire IP address in rules?
-- VPNs -- How do I change an IP on a VPN link if I don't control the
other end? What if I do control the other end, but it is remote?
-- If /48 prefix changes, will my customers/vendors/etc. require another
I'm sceptical that the technology exists today to easily renumber a
business network if a /48 prefix changes.
