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 172 Million).

Both these databases can be queried through our Powerful API.
