Rankings Gone Due To Spoofed IP

[moviepage]

I hope the offender is not only banned, but also that my website gets back its lost juice. Since this incident, my homepage does not even show up when I type in site:http://www.example.com in the Google Search bar. My homepage rankings have completely disappeared.

Let me to go into more detail. When you type my domain name into Google's search bar, the first result is www.theoffender.org. The website was some how displaying my website under its domain. After working with a Unix Administrator at my hosting company, it was discovered that owner of www.theoffender.org was capitalizing on ad and referral revenue by creating an A record that pointed to my server's primary IP. So the Unix Administrator adding the following code to my website:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^(www\.)?theoffender\.org [NC]
RewriteRule ^/(.*) http://www.example.com/$1 [L]

The above causes my server to redirect www.theoffender.org, whenever it uses my IP address, to www.example.com.

But because of this issue, my homepage is not even listed in Google. The site is clearly spoofing my IP, for example in (my modified version of) Firefox, "xx.xx.xx.xx" appears over both the theoffender.org and my site's link in the Google results.

My question is, what can I do to get my homepage rankings back?

IP Spoofing - sheesh! That can be a bear to counteract, depending on what kind of spoofing it is. I was just reading up on it at the Internet Security Systems [iss.net] website.

Once you've got it fixed, your rankings should return quickly, assuming your analysis is accurate and complete. If they don't come back, just use a verified Webmaster Tools account to drop a note to Google and ask for a Reconsideration request.
