why not use the dig command to query your isp dns system to see if
they forward requests to opendns.  By the way, OpenDNS is a great way
to help prevent phishing attacks.

Lastly, you should use this opp to create a opendns signon, this will
give you control over your dns request options.  You could block any
domain via dns quikly.
