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.
Rob: What other parameters or arguments I should add onto the dig command, to see if they use opendns.com ? I don't see opendns.com in the below, but probably that is not the correct dig command.

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.
I will look at the opendns.com web site. I just cannot imagine that the Firefox browser is ending up at opendns.com (intermittently) on it's own. It must be coming from the DNS we are using. Thanks much! Lanny
