Reverse IP/DNS is among the most comprehensive repositories of DNS history data, spanning 1.4 billion domains and subdomains and over 815 million IPv4 addresses. The data is available via a lookup tool, an API, or as a downloadable database updated daily.
Our subdomain finder tools include a lookup, an API, and a data feed, and allow you to get a list of all the subdomains of a root domain. The tool obtains data from a database containing over 2.3 billion subdomains, with over 1 million records added daily.
WHOIS history tools allow you to uncover the past ownership information of 582+ million domain names. Integrate the historical WHOIS data into cybersecurity systems and derive context from the ownership details of suspicious domains before WHOIS redaction.
