Hi,

I am just wondering what takes to make a site like co.cc. When you sign up with them, you get a subdomain like http://yourname.co.cc

How are they able to provide DNS service for subdomains?



Thanx

just like any other host does, it's only an entry in the DNS zone file.

I know how to make a wildcard DNS entry for subdomains such that anything.mydomain.com would be directed to a folder on my server.

But how do I make a DNS settings so that subdomain anything.mydomain.com would have a nameservers pointing to a different server?

Assuming I am running cPanel on Apache

Thanx

create an "A" record

and make it point to?

the server where the site is located

if you are the dns authority for
domain.com
and you want the dns authority for
sub.domain.com
to be a list of other name servers then thats called DNS delegation and you can do that by setting up a number of NS records for sub.domain.com.

You can also delegate domain.com directly, but it would be better to just change the authoritative name servers at the registrar
