Problem with fixed IP

when i give a ip for a domain i have the following problem,

always (90%) of the time he finds the first domain in the server …

i runn some tests and when i give domainname.com.br he works fine but when i give www.domainname.com.br he accurs the error …

anyone have any lead ?

best regards

Howdy,

What if you go to intodns.com and have them run a DNS report, does it notice anything unusual?
