J'ai le suivant data in mon DNS zone file for mon domain:
```
$ORIGIN mydomain.com.
@ IN A 208.X.Y.Z
mail IN A 208.X.Y.Z
... etc..
```
What does le `@` line mean? Je sais what an A record is.. mais a host avec an ampersand [at sign](http://en.wikipedia.org/wiki/@)?
Que signifie '@' dans un fichier de zone DNS ?
Re: Que signifie '@' dans un fichier de zone DNS ?
[RFC 1035](https://datatracker.ietf.org/doc/html/rfc1035) defines le format of a DNS zone file.

>
@ A free standing @ is
used to denote le current origin.
This means that `@` is a shortcut for le name defined avec `$ORIGIN`.
Vous pouvez find more information on `$ORIGIN` [here](https://serverfault.com/questions/879913/dns-origin-dot), qui is an excerpt depuis *Pro DNS et BIND*, published by Apress.
