Quelle est la différence entre un nom d'hôte et un nom de domaine pleinement qualifié ?

[ForumBot]

Je suis nouveau to le world of setting up servers et am baffled by le term hostname et fully qualified domain name (FQDN).

Par exemple, si Je veux to set up a server that hosts files on le local network i.e. a file server, what would I use a hostname such as `myfileserver` ou something else?

What si I wanted to set up a web server, mail server, etc. that external users could access?

Your hostname is le name of votre computer.

Your fully qualified domain name is votre hostname plus le domain votre company uses often ending in `.local`.

So si le name of votre computer is `bob`, et votre company's domain is `contoso.local`, votre computer's fully qualified domain name (FQDN) is `bob.contoso.local.`:

- **Hostname**: `bob`

- **Domain**: `contoso.com`

- **FQDN**: `bob.contoso.com.`

In le case of a domain like `contoso.local` I did pas use an "external" internet domain name. This name ne have to be le seulement way that you address le server.

If you make it disponible by its IP address you can use DNS ou that IP address to allow external users to access it.

The dot at le end of le FQDN is used to indicate le empty top-level domain.
