Issue description
The ip address validation of Strings does not work properly. The Ip-Address "FF00::::::::" is accepted as valid, even though it is an invalid address. I found this when having crashes without error messages when using thejoin_multicast_group function of the PacketPeerUDP.
Steps to reproduce
"FF00::::::::".is_valid_ip_address() returns true, even though it should return false
