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.

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!
