How do the domain, website, registrar, registrant and hosting provider fit together?¶
They describe different parts of the same service.
The five roles¶
The domain is the human-readable name. The website is the content and functionality reached through that name. The registrar supplies the registration account. The registrant is the recorded holder of that registration. The hosting provider supplies computing infrastructure.
A useful analogy is a business using a trading name. The domain is the name on the sign, the registrar manages the right to use that sign, the registrant is the recorded customer, and the host supplies the premises. The website is what the business presents and does inside.
The roles can belong to different organisations. A developer may register the domain for a client, a cloud platform may host it, a content-delivery network may sit in front and employees may publish through a separate website platform.
Each layer tends to hold different records. Registrars hold registration-account evidence; hosts hold customer and infrastructure evidence; platforms may hold publishing and user activity; payment providers hold transaction and beneficiary records.
Timing matters across every layer because registration, hosting and control can change independently. Repeated identifiers across several providers - such as an email address, payment method or administrator login - can join the layers, but each connection should be described precisely.
The point to remember
Domain, registration, hosting and publishing are connected roles, not interchangeable labels.
