I see that Brano
provided the correct explanation for your previous question.
said by tomdlgns:i went to welcome.opendns.com before i made my changes and it said ooops, you are not using openDNS. i made my changes and went to welcome.opendns.com again and it gave me the check mark confirming that i was pointing to them.
The way that I would test if OpenDNS is working as my resolver is by using a non-existing domain like
nitwit.biz in my browser and see if the response opens the OpenDNS Guide -- if YES -- then that's the verification I am looking for and want.
