How domain registration actually works
KB-1.7 · 1 min · Updated September 2026
Three parties make domain registration work:
ICANN (the Internet Corporation for Assigned Names and Numbers) sets the overall policy rules for how domain names work globally and accredits the companies allowed to sell them.
Registries operate individual TLDs. They maintain the authoritative database of every domain registered under that TLD and set its wholesale pricing.
Registrars — ICANN-accredited companies like NameBright — are who you actually buy from. A registrar sells registrations on the registry's behalf, handles your account and billing, and is your point of contact for changes, renewals, and transfers.
When you register a domain, your registrar submits that registration to the relevant registry, which adds it to the TLD's official record. That's also why domain transfers move you between registrars, not between registries; the registry doesn't change, only who manages your registration with them does.
