`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_THIRDPARTY, DnsProvider("DNS_BIND"),
  SOA("@", "ns3.example.org.", "hostmaster@example.org", 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](../../providers/bind.md).
