ANSWER:

If you take a look at your name servers:

http://host.robtex.com/ns2.hostinginmind.com.html#records you can clearly see this is on their network. What’s happened at some point in DECEMBER 2012 your site was operating on that domain. Now the problem seems fixed as http://0.3c.7aae.static.theplanet.com no longer works. It may take a couple of weeks for Google to catchup. Personally I’d contact Google as there’s nothing you end you can do unless you have ownership of theplanet.com….

If own theplanet.com do a move site request.
