Create a "foo" zone on a master and some secondaries, delegate "bar.foo",
"pizza.foo" and any other subdomain from that internal "foo" zone. Then, on all of
your nameservers, define "foo" as either 1) a "forward only" zone pointing to
internal servers that can and will recursively resolve queries in that domain, or
2) a master/slave/stub, cancelling forwarding for the hierarchy by using the
"forwarders {}" syntax.
