Re: how to relocate servers transparently
That's right for the case of bind using another bind as forwarder!
I mean asking the first bind or asking the forwarder at the same time
would result in the same TTL.
Don't know about other DNS server types.

Can you explain that a little further? If my nameserver caches a record with
TTL 86400, and someone asks for it again an hour later I hand them the record
from my cache using TTL 82800 (not 86400). This is certainly what bind does,
if other caching nameservers do it differently then it's a bug IMHO.
I would be very surprised if it is different when DNS queries are being
forward from one DNS server to another. Or did you mean something else?
