Amigo é só criar entradas A ns1 e ns2 com os IPs do servidor, exemplo:

ns1.xxx.com A 1.1.1.1

ns2.xxx.com A 1.1.1.2

Resolvi pra ele lá, o DC tinha passado um IP que já estava em uso, aí dava problema no Registro.br :P. Também tinha uns problemas na configuração do NSD, fiz a troca para o BIND.

rodrigo voltou da aquela mensagem de erro nos dns do meu servidor mesmo depois que vc mecheu veja IMPORTANT: Do not ignore this email.

The hostname (serv10.volarehost.com.br) resolves to 67.159.33.34.

It should resolve to 66.90.101.63. Please be sure that the contents

of /etc/hosts are configured correctly, and also that there is a

correct 'A' entry for the domain in the zone file.

Some or all of these problems can be caused by /etc/resolv.conf

being setup incorrectly. Please check that file if you believe

everything else is correct.

You may be able to automatically correct this problem by using the

'Add an A entry for your hostname' option under 'Dns Functions' in

your Web Host Manager.
