[Pdns-users] Authority Question

I've never done this with forward lookup delegation, but I am currently
delegation control over one of our class C IP blocks for reverse PTR lookup
to one of our customers by simply adding a SOA record and then two NS
records.  And of course those NS records point to the dns servers we are
delegating to.

The "name" column looks like:  100.168.192.in-addr.arpa
The "type" column is: NS
And the "content" column looks like: ns1.customersdnsbox.com

I'm thinking you might be able to change the name column to "yourdomain.com"
to achieve the same affect for forward lookups.

Just a thought ;-)

Hope this helps.

Thanks everyone!

I was aware this was sort of a non standard way to do this. On the
flipside, is it possible that my domain xyz.com which I am authoritive
for to be delegated to a third party completely, e.g. if the root
servers have NS records for xyz.com pointed to ns1.xyz.com and
ns2.xyz.com, can I in turn delegate the entire xyz.com to a third party,
by way of adding NS records within ns1/ns2.xyz.com which point to
ns1.abc.com? I was having trouble with this concept as well. E.g.
instead of delegating a subdomain/zone, I want to delegate the entire

Thanks again,

Maybe you can allow recursion and point the recursor to the third party
server. Otherwise it's non standard way to solve your problem. What is
the problem with adding zones? That's way they exist.
