priv/zones/ZONES.md
# Zones
erldns reads zone files from this folder, and loads them on start. Zones must be formatted as JSON, and stored in `.json` files.
## Default zones
All `.json` files within this folder are default zones, packaged with the default `erldns` distribution. They are used to bootstrap the state when you start the project.
## Custom zones
You can place your custom zones files inside the `priv/zones/local` directory. The content of this folder is not tracked by version control, and you can use it freely to add more zones for any purpose.
## JSON files
A JSON zone file contains an array of 1 or more zones. Each zone has a name and an array of records. Each record has a name, type, ttl and data field. The data field contains a JSON object with one or more attributes that are appropriate for the specific record type.
### Example
The follow is an example of a collection of zones with a single zone in the collection:
```json
[
{
"name": "example.com",
"records": [
{
"name": "example.com",
"type": "SOA",
"ttl": 3600,
"data": {
"mname": "ns1.example.com",
"rname": "admin.example.com",
"serial": 1234567,
"refresh": 1,
"retry": 1,
"expire": 1,
"minimum": 1
}
},
{
"name": "example.com",
"type": "A",
"ttl": 3600,
"data": {
"ip": "1.2.3.4"
}
},
{
"name": "example.com",
"type": "MX",
"ttl": 3600,
"data": {
"preference": 10,
"exchange": "mail.example.com"
}
}
]
}
]
```
