This method seems to be duplicated in your project.

    {
        if (filter_var($ip, FILTER_VALIDATE_IP, FILTER_FLAG_IPV6) === false) {
            throw InvalidPointTypeException::point('IPv6', $ip);
        }

        $this->ip = $ip;
        $this->long = inet_pton($ip);

The property $long was declared of type integer, but inet_pton($ip) is of type string. Maybe add a type cast?
