Bind forward zones
A forward zone is a particular type of zone which is useful
to configure a per-domain forwarding policy. All queries for the domain given
by the zone name will be forwarder to the servers specified in the
forwarders
statement, instead of being forwarded to the default
forwarders (if any).
A forward zone can be defined as follow:
zone "my.domain.tld" { type forward; forward only; forwarders { 1.2.3.4; }; };
