a domain default resolution

[Montse Seisdedos]

Hello everybody:
I want all sumdomains of a domain to resolve to a IP by default. That is:

xxx.mydomain.com -> default ip
yyy.mydomain.com -> default ip 

xxx, yyy is something that is not defined in mydomain.com file.


I found a question in the FAQ archive about the same subget  but i couldn't find the answer.

Can anybody help me?
Thanks in advance.
