Hello,

Thanks for your response.
In fact I meant I want to change the nameservers for cloudwebdns.com to 
our own servers. Not the DNSbed's NS.

After I added the zone cloudwebdns.com to named.conf and created the 
zone files and reloaded BIND (in fact all these steps are done by the 
system automatically), I run into the dig problem:

pyh at cloudserver19:~$ dig cloudwebdns.com soa @localhost

For querying both SOA and NS records I just got SERVFAIL.
So I am not sure what happens.

Thanks.
