What Is a Domain Registrar and Why It Matters
Definition
A domain registrar is a company accredited by ICANN (Internet Corporation for Assigned Names and Numbers) that can register your domain name directly with top‑level domain systems like .com, .org, .net and country codes (ccTLDs). Registration involves DNS, WHOIS, registry, renewal, and domain management.
Why Accreditation and Registry Access Matter
Only accredited registrars can submit your domain name registration directly into the global registry system (Shared Registry System) under standard DNS and WHOIS controls. This impacts:
- DNS propagation speed
- Renewal rules and transfer control
- Domain availability accuracy
- Security and abuse response policies
Both NiceNIC and GMO Internet Group hold ICANN accreditation, meaning they meet global policy requirements for domain registration.
