For the second time... the difference is ns1.mydomain-1.com is registered at the TLD's and ns1.mydomain-2.com is NOT. Name Server (NS) records (especially the SOA) need to (should) match the registration at the TLD's. FWIW: I would have liked to have setup my zone files as you have shown above, but because I only have one public IP address, I was unable to register ns1.mydomain-2.com as a name server (NS) at my registrar; so I had to use ns1.mydomain-1.com. So that you can fully comprehend what I'm talking about, use dig's trace mode against your registered domains and watch the recursion from the root name servers. (Substitute mydomain-1.com with your registered domain names) dig +trace mydomain-1.com ns dig +trace mydomain-2.com ns In my case, mydomain-2.com would return the same NS records as mydomain-1.com because I only have one public IP address that I could register at the TLD's. If you have more that one IP address that can be registered, then you will not have this problem and can follow your example posted above. Any further questions can be answered by reading the DNS & BIND book.
