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).

You could do it as 16 separate /16 forwards but obviously that would be very ugly and doing it for a /17 would be much worse...
