Dedicated server host static url showing up in search results.

[riospace]

I am so confused. I have a

dedicated

server hosted by The Planet and recently I have noticed that in Google search results from my site that the weird url below is showing for many of the search results for my site instead of the actual sites url.

http://b4.40.344a.static.my-server-host-url.com/

instead of:

http://www.my-website-url.com/

What is going on? This is way over my head?

[edit reason] I made the example urls fully visible [/edit]

1) Somebody, somewhere, linked to that URL,
and
2) You took no steps to 301-redirect non-canonical hostname requests to the canonical hostname before your site went live.

A great past thread title here was, "Duplicate content - Get it right or perish." Try searching WebmasterWorld for "duplicate content" and "canonical domain" for more info.

Here is what my host tech. told me:

The following is pulling from reverse ptr records for the domain. As your domain [my-website-url.com...] resolves to the ip xx.xx.xx.#*$!x, the ip is showing to resolve the the planet default record [b4.40.344a.static.my-server-host-url.com...] . I have updated the ptr record of the ip xx.xx.xx.#*$!x! to resolve to the domain [my-website-url.com...] . Please allow 4 to 6 hours to update.

Is there an .htaccess rule that I could also have used to solve this problem? If so, what would it look like?
