I have the EXACT same problem that was addressed in a former thread on Stack Exchange here:
As you can see from the image above from the
site: command in Google, someone has created subdomains off of my domain. The results seem to be in Russian and, even worse, the subdomain part of their URLs are explicit content terms.
I have NEVER clicked on any of these results for fear of viruses etc.
My website is hosted at HostGator and trying to even explain this problem to their tech support has been very difficult.
I went into my cPanel and checked if there were subdomains there: No. I checked a couple other things: Nothing odd.
And from the link I posted above to another similar thread, the answer Chris Rutherfurd gave is probably my problem, as well but I don't understand the problem well enough to 1) fix it myself or 2) simplify it enough to explain to the Hostgator tech support person.
I still don't know if the problem is with HostGator or my registrar (Network Solutions).
Can anyone help?
In the comments below, Vladislav has pointed me in the right direction I think. I found a website that runs the
dig command for you and got some output including an IP address in Provost Utah for a company called Unified Layer - I think this is BlueHost and that BlueHost and Hostgator are now owned by the same company.
