WhoisXML’s Reverse IP is a new tool that identifies every domain names associated to a given IP address (and vise versa). This allows users to ascertain all possible affiliations between IP addresses and domain names.
Reverse IP is also known as Reverse DNS Lookup. The process of using Reverse IP involves entering an IP address or domain name into the DNS search database, and the system will reveal all possible links associated with either the IP or domain name.
Reverse IP can also be used to detect IP addresses associated with website security breaches.
Reverse IP allows users to improve online security by identifying fraudulent websites and any IP or domain name associated to it. Reverse IP API can also identify host names of cyber attackers, revealing all host IPs associated to these hosts. Reverse IP API is also used by brand management companies to identify hosts with fraudulent websites.
The tool also displays all domain names and IP addresses hosted on a shared server. With this information, users can prevent their websites from being linked to other (less reputable or fraudulent) website IPs and domains (consequently increasing search engine ranking). The service has a free and a paid option.
Whois XML API also developed Reverse MX (https://reverse-mx-api.whoisxmlapi.com), a tool that identifies all domains associated to a particular mail server. This helps users prevent their mail servers from being blacklisted.
Reverse NS is another tool launched by Whois XML API. Reverse NS API (https://reverse-ns-api.whoisxmlapi.com/) allows users access to the largest database of name servers.
All tools have an API associated with them for easy programmatic access.
