A DNS server can be configured to have any number of domains, whether it is running BIND or any other DNS server.

Yes, this is what i look for.

Excellent support.

Thanks a lot.
The DNS server is the pointer for those domains.

abc.com => 10.10.10.1
xyz.com => 10.10.10.1

The bind software is configured to resolve these zone
zone abc.com  => record details (SOA, A, CNAME, www, mail)
zone xyz.com  => record details (SOA, A, CNAME, www, mail)
Hi Rindi -
The question was for explanation of how the config file work for DNS.  I provided basic files and in response 22729761 he said
"Yes, this is what i look for.  Excellent support."

So I think that answers it.
