Reverse IP Domain Check. Use this free SEO tool to lookup any top level domains hosted on a given IP address. A reverse IP domain check takes a domain name or IP address pointing to a web server and searches for other sites hosted on the same web server. Data can also be gathered from search engine results pages (SERP), but are not guaranteed to be accurate. Knowing the other web sites hosted on a web server can be important when analyzing a competitor's SEO.
