# Not

- `Not(Validator $validator)`

Negates any validator.

```php
v::not(v::ip())->assert('foo');
// Validation passes successfully
```

In the sample above, validator returns true because 'foo' isn't an IP Address.

You can negate complex, grouped or chained validators as well:

```php
v::not(v::intVal()->positive())->assert(-1.5);
// Validation passes successfully
```

Each other validation has custom messages for negated validators.
