Research domain ownership.
History products enable you to research domain ownership to find the owner of a domain you wish to buy or the provenance of a domain before a negotiation.
Monitor your interests.
Monitor products enable you to track brand names for new registrations, whether a registrant picks up or drops domains, as domains are added or removed to a name server.
Start with TLDpedia.
DomainTools TLDpedia and statistics pages are a great starting point for tracking the growth of new TLDs, finding the registry behind new or existing TLDs or the world’s allocation of IP addresses or domains by IP block.
