IP addresses ranging between 172.16.0.0 to 172.31.255.255 are now treated as LAN when determining which country an IP address originates from.
The following IPv4 address ranges are also reserved for private networks: 172.16.0.0
to 172.31.255.255
(https://en.wikipedia.org/wiki/Private_network). Previously, Zandronum didn't treat IP addresses in this range as LAN when determining which country a player connected from, but they should be treated as such.
