subdomain delegation and A record problem

[Blake]

I have a root AD integrated zone, domain.com

I have a subdomain abc.domain.com, which is delegated (it is run by someone
else)

Can I create an A record for host.abc.domain.com on MY server?

Thanks
Blake

If all you need is one name host.abc.domain.com, you can create a forward
lookup zone named "host.abc.domain.com" (without the quotes), then create
one new host record in the zone, leave the name field blank and give it the
name you need host.abc.domain.com to resolve to. If there are other names
under abc.domain.com, you need resolved differently than they are already
resolved, create the zone named "abc.domain.com", in the zone create the
record named host and/or any other name you need to resolve.

Hi Kevin,

I was thinking, wouldn't the "abc" subdomain's DC/DNS already have the Zone
for "abc"? Wouldn't it be better for the admin of the "abc" Child domain to
just create the Host Record (if it isn't already done Dynamically) and the
whole Forest would already know about it via the normal replication? I used
to be in a Child Domain before we got sold to another company and that is
how it worked for us. No one ever created zones/records for my hosts higher
up in the Forest.

If I read Blake's original post correctly, he said someone else delegated
abc.domain.com to his DNS and didn't say anything about already having a
zone in that domain tree on his DNS. That being the case, a zone named
abc.domain.com needs to be created. Thinking of it, even if a domain.com
zone already existed, it should still be a separate zone, containing the NS
record with the same name the delegating DNS server uses.

Thanks, guys for your input to date.

I run domain.com.

Somebody else runs abc.domain.com - so my users can resolve it, it is
delegated in my AD DNS to somebody else (running BIND, not that that matters
here).

The owner of abc.domain.com wants to advertise ns.abc.domain.com as the
nameserver for abc.domain.com.

Right now I have a simple delegation for abc.domain.com pointing to
ns.abc.domain.com. Problem: my users can't resolve ns.abc.domain.com, so
the delegated zone isn't doing me any good. And I can't create an A record
for something that 'belongs' in that delegated zone.

I think a stub zone is the answer. I would create a stub for
abc.domain.com, pointing to the NS boxes for that domain - and it should
behave similiar to the delegation, but I'll have an A record available (in
the stub zone).

Thoughts?

I see your reasoning, but as the A record is a name server, there might be
more than one in the future

Thanks Phillip, but this is a heterogeneous environment - the owners of
abc.domain.com are linux guys.

Follow my original example by creating a forward lookup zone named
"ns.abc.domain.com" with the single @ host record with the IP of the server.
This will act as your Glue and will only resolve that name, All other names
in abc.domain.com will follow the delegation.
