Recently i found out that my site was captured under a different domain name . When i was searching for some link in google there was a link which was pointing to my website's page but the domain name was entirely different from mine . I checked in my server that IIS was bound to all HTTP request coming through port 80 to my site hence someone just used my ip address under their domain name and started publishing my site under it .
Solution to this problem is simple, bind your website in IIS to specific domain and never leave domain binding empty else you could also face the same problem .
