Host with Public IPv4 Address Validator

Laminas\Validator\HostWithPublicIPv4Address allows you to validate that an IP address is not a reserved address such as 127.0.0.1, or that a hostname does not point to a known, reserved address.

Basic usage

$validator = new Laminas\Validator\HostWithPublicIPv4Address();

if ($validator->isValid('example.com')) {
    // hostname appears to be valid
} else {
    // hostname is invalid; print the reasons
    foreach ($validator->getMessages() as $message) {
        echo "$message\n";
    }
}

$validator = new Laminas\Validator\HostWithPublicIPv4Address();

if ($validator->isValid('192.168.0.1')) {
    // hostname appears to be valid
} else {
    // hostname is invalid; print the reasons
    foreach ($validator->getMessages() as $message) {
        echo "$message\n";
    }
}

Hostnames with multiple records

When validating a hostname as opposed to an IP address, if that hostname resolves to multiple IPv4 addresses and any of those addresses are private or reserved, then the validator will deem the hostname invalid.
