About
ultimatedata.org is a reverse whois domain name ownership database. We offer active domain name whois records and historic domain name whois records that are updated regularly. Archived data is available on many domain names and grows each quarter. The data can be used to research individual domains and owners or entire portfolios of domain names.
ultimatedata.org is an exceptionally useful tool for tracking connections between domain names, cross referencing ownership details, and brand monitoring. Need more details? Order a custom report or contact us about custom enterprise level needs.
The data on ultimatedata.org is not live, it is updated quarterly. ultimatedata.org should be considered a general interest/research tool that is based on whois data. Not all domain extensions are included and not all included extensions are completely indexed.
