Registry? Registrar? Reseller? Registrant? What
do these words mean?
Registrar: A "Registrar" (or "Domain Name Registrar") is an organization
like Tucows or 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 registrars 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.
Reseller: A reseller is a company that uses the Tucows/OpenSRS registrar
system to provide domain registration services to the general public. All City
Solutions is a Tucows/OpenSRS reseller.
Registrant: A registrant is the person or company who purchases a domain
name. For example, Jessica Smith (registrant) registers the name example.com
through an OpenSRS Reseller.
