Hi

How important is it to have these records setup if you run your own dns servers?

I am almost sure it worked when I set them up, but now, after adding another subdomain on the main domain I can`t do a nslookup on the ip adresse of ns1.mydomain.com. I get an error saying "can't find 216...". What can go wrong on a Cobalt Raq4 preventing this from working? Can any external issues (my provider Raqshack) influence this and prevent it from working?

Forgot to mention that when I ask the nameserver, in question, directly through nslookup, then it gives me the correct result.

Anyone have an idea what I have done wrong?

It's probably because your provider hasn't made the IPs you are trying to get to resolve go through your nameservers. Something like this would do it:

Let's say your ip is 100.200.225.250, this is what raqshack would need to put in the zone 225.200.100.in-addr.arpa in order to point the ip at your nameservers:

250.225.200.100.in-addr.arpa. IN NS ns.yournameservers.com.

Ok, so it is`nt enough that I have set up the in-addr.arpa records on my dns servers?

Oh, and is it important that I have raqshack set this up for me?
