    Simple. Create NS record for subdomain. For example, if your domain is
    bar.com, and you want to delegate foo.bar.com:

    foo IN NS dns1.foo.bar.com.
                       IN NS dns2.foo.bar.com.
    dns1.foo.bar.com. IN A 1.2.3.4
    dns2.foo.bar.com. IN A 1.2.3.5

    Make sure you don't ommit any of those dots ;-)

    Basically, this tells your local BIND that dns1.foo.bar.com and
    dns2.foo.bar.com are name servers for foo.bar.com domain. You must
    include A records for those two servers on parent server (as shown
    above) so that resolvers have enough information to contact them. The
    above example is if you want to have two servers for foo.bar.com. You
    can have only one if you want. Or three. Or any number of them. Make
    sure you list all of them on parent server (no much point in having
    multiple servers if nobody outside domain knows about them).

    There are many online resources describing this. You might also
    consider getting copy of "DNS and BIND" (4th edition also covers BIND 9,
    so you probably want to make sure you get that one, not the older
    editions) written by Paul Albitz & Cricket Liu, publisher is O'Reilly.
