Registrar: A "Registrar" (or "
Domain Name Registrar") is an organization like Network Solutions that has control over the granting of
domains within certain TLDs (top level domains, like the generic .com/.org/.net or country-specific .ca/.us/.mx etc.).
Registry: The 'Registry' is the backend that registrar's have shared access to. Each registrar writes new names to a central registry database, from which the authoritative root (essentially, a table of all domain names on the Internet) is built.
Registrant: A registrant is the person or company who
purchases a domain name. For example, Megrisoft (registrant) registers the name megrisoft.com through Directi (registrar) who in turn writes the name to the central database (Registry).
