Steve..
Much thanks for the suggestion..
My current platform is an ESX VM CentOS 5.5 (very minimal install and
currently bind 9.6.2..
I can "dual home" it but need to really do some testing on bind
listening on 2 IP addresses..
We were actually moving down this road.. (a new "box")
I have an external dns server that uses dnssec and bind 9.7.1-P2..
(compiled from source), will soon be on that platform with the new "box"..

if you've got spare hardware, you can set up a new server on the new IP, and
make the old server a secondary. Phase it out over time.
Alternatively, depending on the OS, you can set up a secondary ip address on
the server and answer queries on both addresses on the same box. Again phase
out the old address when possible.
The first scenario may make it easier to detect queries to the old address, to
make sure all clients have been migrated.
Either way, you'll probably have to juggle hostnames somewhere along the way,
but this shouldn't affect the clients, as they'll hit your servers by ip
address.

Subject: migrate to a different IP
Overview
- internal DNS server with RFC1918 IP (old ip)
- wish to move to a global unique IP but still remain internal (new ip)
- keep the same name
Clients would still use the old IP until the migration had been completed.
What would be the preferred method to "forward" all requests from
the old IP to the new IP..?
The final config will be with the new box on the new IP address
or am i barking up the wrong tree ??
Thx
Charles
