DNS Forwarder

[Herb Martin]

A forwarder is probably not critical to the solution
(it may be necessary for reasons you do not describe).

Keep both DNS server sets running throughout the
changeover -- make sure clients can reach either
until they are weened off the old names (this may
be where you need to forward even.)

Normally, clients reach all names in the namespace
by asking a DNS server to recurse, the DNS server
does this by going to the ROOT and working it's way
down to the needed information.

The alternative is for the DNS server to forward to another
DNS server for names it doesn't hold, but then it is totally
dependent on that other (forwarder) DNS server -- in most
cases -- to resolve all names it doesn't hold.

If you only have two zones, a forwarder can work (don't
make them circular though, e.g, a->b->a XXX)

If you don't have a common root and only have two zones,
it is probably best for each DNS server set to hold secondaries
for the opposite zone.

'forwarder' from one domain to another or whether should have the secondary
zone of other domain?
