Local network restriction does not support IPv6 global unicast addresses

[nomis]

The problem

The "can only log in from the local network" restriction on users doesn't work when the network uses IPv6 global unicast addresses (2000::/3) because only unique local addresses (fd00::/8) are considered to be local.

The local IPv6 network needs to be auto-detected and/or the IP addresses that are considered to be in "the local network" needs to be configurable.
