What you mean with "according to IP ranges/domain names"?
[...]
- if you want redirect target domains to different servers you can use
BIND and forward zones:
I would want to be able to do that based on domain names (which is
easily done with BIND) and on classless IP ranges. I don't think the
latter can be done as the IP ranges are octet-granular, e.g.
10.in-addr.arpa for 10.0.0.0/8 -- I can't imagine how I would tell BIND
to use a certain server for e.g. 10.1.0.0/12 (where 4 MSB of the second
octet are part of the network address and the remaining 4 LSB are part
of the host address).
For private ranges/domain views, you'd normally either have a local DNS
server configured as primary or secondary for those zones that can
also resolve public addresses, or for roaming vpn users you'd use a
similar central private server that can resolve everything, public or
private while you are connected. You'll quickly go insane if you try to
mix unrelated private connections (for example, if there really are
different parts of your 10.x.x.x range that don't know about each
other). If there isn't some 'other' part of your 10.x range, you can
point the whole /8 to a server that knows about the part you use.
