# DEFAULTS

`DEFAULTS` allows you to declare a set of default arguments to apply to all subsequent domains. Subsequent calls to [`D`](https://docs.dnscontrol.org/~/revisions/T4Wre387kGCjR4Bh4mfN/language-reference/top-level-functions/d) will have these arguments passed as if they were the first modifiers in the argument list.

### Example

We want to create backup zone files for all domains, but not actually register them. Also create a [`DefaultTTL`](https://docs.dnscontrol.org/~/revisions/T4Wre387kGCjR4Bh4mfN/language-reference/domain-modifiers/defaultttl). The domain `example.com` will have the defaults set.

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

```javascript
var COMMON = NewDnsProvider("foo");
DEFAULTS(
  DnsProvider(COMMON, 0),
  DefaultTTL("1d")
);

D("example.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
  A("@","1.2.3.4")
);
```

{% endcode %}

If you want to clear the defaults, you can do the following. The domain `example2.com` will **not** have the defaults set.

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

```javascript
DEFAULTS();

D("example2.com", REG_MY_PROVIDER, DnsProvider(DSP_MY_PROVIDER),
  A("@","1.2.3.4")
);
```

{% endcode %}
