IP / DNS - Sorcery
Found the site in the search results with the correct html title content, but the displayed domain is incorrect (notmydomain.com). It isn't even owned by the company.
It seems notmydomain.com is pointing to my linode IP address.
Checked the IP / DNS info on linode and the domain registrar which as far as I can tell looks correct.
Whatever is going on feels out of my depth of knowledge. Your input would be appreciated. Thank you.
my_domain.com is (likely) setup as the default virtual host in your web server config. Your web server is happily serving up content to anyone that comes by, no matter what domain they ask for.
You can change your web server config to use a different default vhost that either displays some message for unknown domains, or does a 301/302 redirect to my_domain.com.
Gee I guess we don't need those pesky details after all.
What are the real domain names?
By the sound of it this is either another domain pointed to your in error, or a troll ripping off your website content.
The page is pretty basic; it's currently just an e-mail subscribe form.
Now, the r33.cooltext.com results are still appearing in Google, but they take visitors to an error message instead of your site, and you have to wait until Google rediscovers the site at the new, correct URL. As far as I can tell, virtually nothing was gained by pestering the cooltext.com people, and you ended up screwing up your search results.
Elegant solution, dcraig.
