描述：This tool performs a reverse IP domain check which takes the domain name or IP address of a web server and searches for other sites known to be hosted on that same web server. Data is gathered from search engine results, which is not guaranteed to be complete. Knowing the other web sites hosted on a web server is important from both an SEO and web filtering perspective, particularly for those on shared web hosting plans.
