# SOA

`SOA` adds an `SOA` record to a domain. The name should be `@`. ns and mbox are strings. The other fields are unsigned 32-bit ints.

{% code title="dnsconfig.js" %}

```javascript
D("example.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
  SOA("@", "ns3.example.com.", "hostmaster@example.com", 3600, 600, 604800, 1440),
);
```

{% endcode %}

If you accidentally include an `@` in the email field DNSControl will quietly change it to a `.`. This way you can specify a human-readable email address when you are making it easier for spammers how to find you.

### Notes

* The serial number is managed automatically. It isn't even a field in `SOA()`.
* Most providers automatically generate SOA records. They will ignore any `SOA()` statements.
* The mbox field should not be set to a real email address unless you love spam and hate your privacy.

There is more info about `SOA` in the documentation for the [BIND provider](https://docs.dnscontrol.org/~/revisions/T4Wre387kGCjR4Bh4mfN/service-providers/providers/bind).
