block.opendns.com blocking websites on Safari.

I was viewing a video from youtube last night when, suddenly, Safari stopped working. Every time I tried to open a website, it would reroute to" block.opendns.com" showing the page below. I could however receive mail.

I finally figured out that my DNS Server had somehow been changed to 208.67.222.222. Through a google search of this issue I found others were having the same problem. Just wanted you to be aware so others might be helped with this issue.
