delegating NS control of subdomain to another BIND

[David Kirk]

You need to have glue records in the parent domain file, so that the
delegation
works properly.

Basically, you'd need the following in your parent domain (assuming parent
zone
of madduck.net for example's sake) ...

In MADDUCK.NET ...

subdomain           IN        NS        ns1.subdomain.madduck.net.
subdomain           IN        NS        ns2.subdomain.madduck.net.
ns1.subdomain     IN        A          192.168.14.13
ns1.subdomain     IN        A          192.168.14.14

... and then have all of your appropriate entries in the
subdomain.madduck.net
zone.  This is needed due to the hierarchical nature of DNS, and since you
are
delegating the subdomain to servers that live in that subdomain, you need
to make
sure that there is a logical path via DNS to those servers, thus served by
the glue
records (the two A records above).

If you do the above, everything should work for you, unless I'm missing
something
really basic..

Thanks,

dave
