The `isValidIP` operator checks if the value is a valid IP address. The `isValidIPv4` and `isValidIPv6` operators check if the value is a valid IPv4 or IPv6 address respectively. 

## Syntax

### isValidIP

`isValidIP("<IP_string>") as <field>`

`isValidIP(<IP_string_field>) [as <field>]`

### isValidIPv4

`isValidIPv4("<IP_string>") as <field>`

`isValidIPv4(<IP_string_field>) [as <field>]`

### isValidIPv6

`isValidIPv6("<IP_string>") as <field>`

`isValidIPv6(<IP_string_field>) [as <field>]`

## Rules

* Returns `true` if the input is a valid IP address.

## Examples

```sumo
| isValidIP(dest_host)
```

The following returns `true`:

```sumo
| isValidIP("10.255.255.255") as isIP
```

The following returns `true`:

```sumo
| isValidIP("192.168.0.1") as isIP
```

The following returns `false`:

```sumo
| isValidIP("127.0.500.1") as isIP
```
