The Largest WHOIS Database in the World

We update WHOIS data of over 5 million domain names every day! BigDomainData is made up of 2 primary databases (Current WHOIS Database and Historical WHOIS Database). Our Current WHOIS Database contains the latest WHOIS record of only active domain names (over 265 Million). While the Historical WHOIS Database contains WHOIS history of every domain name (over 560 Million) that was ever registered on the Internet. Both these databases can be queried through our Powerful API.
