[Pdns-users] Authority Question

Tue Jun 7 17:15:51 UTC 2005

Sorry Michael,

I forgot to mention the SOA I am using for the PTR delegation of that class
C is actually for the parent class B network.

IE:  168.192.in-addr.arpa

To delegate the block 100.168.192.in-addr.arpa

Perhaps you would have to create a SOA for ".com" or whatever the TLD is for
your domain.  And then add NS records for "yourdomain.com" using the same
domain ID that you used for your SOA record.

Not sure what adverse affects hosting a ".com" SOA would have.

I am no expert by any means.

Regards,
-Adam

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.

Regards,
-Adam

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
domain.

Thanks again, 

-Michael

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.

Best regards,
