DNS spoofing

One of the ways you can try is to setup a zone for somedomain.com on
your DNS server, assuming your users will query your DNS servers for
any outbound recursive lookups. Just create the entries you want in
somedomain.com, and your users will get those answers.

If your main DNS server is different from the DNS resolver that users
point to, you will need to create a forward zone on the resolver to
point anything in somedomain.com to your main DNS server (where your
own version of the somedomain.com data resides).

Hope this helps.
