Where should I start with the Domains glossary?
Start with domain names and registrants, then explore transfers, registration status, and renewal planning.
- Domain name: A human-readable name in the Domain Name System that identifies a place in its hierarchical namespace.
- Registrant: The person or organization holding the registration rights for a domain under its registration agreement.
- Registrar: An organization through which a registrant registers and manages a domain under the relevant registry's rules.
Which terms separate domain structure from registration work?
- Subdomain: A domain located below another domain in the DNS hierarchy.
- Public suffix: A suffix under which users can register names, including some multi-label and platform-specific boundaries.
- Domain transfer: A change of sponsoring registrar for a domain registration.
Which practical guides build on the Domains terms?
- Map your domain, DNS, website, and email providers: Separate four commonly confused services so a future change goes to the correct account and preserves the services that depend on it.
- Build a domain renewal register: Keep domain ownership and renewal information inspectable so essential names are not dependent on one person's inbox or an unchecked payment setting.
