# Domain
- `v::domain()`
- `v::domain(boolean $tldCheck = true)`
Validates domain names.
```php
v::domain()->validate('google.com');
```
You can skip *top level domain* (TLD) checks to validate internal
domain names:
```php
v::domain(false)->validate('dev.machine.local');
```
This is a composite validator, it validates several rules
internally:
* If input is an IP address, it fails.
* If input contains whitespace, it fails.
* If input does not contain any dots, it fails.
* If input has less than two parts, it fails.
* Input must end with a top-level-domain to pass (if not skipped).
* Each part must be alphanumeric and not start with an hyphen.
* [PunnyCode][] is accepted for [Internationalizing Domain Names in Applications][IDNA].
Messages for this validator will reflect rules above.
