How do you resolve domains to different internal servers on bind-8

Assuming you're running an up-to-date version of BIND 8, you can set up zones
of type stub, slave or forward for the internal domains that you want to
"override" the Internet namespace. Slaving requires that you are allowed to do
zone transfers from the authoritative server(s), and uses significant resources
whenever the zone transfers. Per-domain forwarding and stub'bing don't require
any special permission on the authoritative server(s), and doesn't incur any
zone-transfer overhead, but the flip side is that you don't have a copy of the
zone to fall back on if you can't reach the authoritative servers, so it's a
resources-versus-robustness tradeoff. Note that "stub" is more robust than
per-domain forwarding, at least until 8.2.3 introduces the
forwarder-selection-by-RTT feature, but it requires periodic SOA and/or NS
queries to keep the nameserver information up to date (in a stub file).
