Security and hosting
What is the difference between a domain and hosting?
The domain is the address; hosting is the building. You rent the address annually from a registrar and rent the space from a host. They are separate services, frequently sold together, and keeping them separate makes changing either one straightforward.
What each one holds
- Registrar
- The domain registration and, usually, the DNS zone. Controls where the name points.
- Host
- The files, the database and the certificate. Serves the actual pages.
- DNS
- The connection between the two. Can live at either, or at a third provider.
Why the distinction matters
Changing host means updating one DNS record — an afternoon. Changing registrar means transferring a registration, which takes days and requires an authorisation code. Bundling them makes leaving a poor host feel harder than it is.
The ownership consequence
Hosting can be replaced in a day. A domain registered in someone else’s name is a negotiation. If you check only one thing about your web presence, check the registrant on your domain.
