Update .NET version to make it compile on my computer
Correct use of .NETs IsIPv6UniqueLocal. It's actually unsupported on IPv4, previously it gave false positives.
Include Rust's support for is_unicast_link_local
Differentes remain:
Go and Rust have different opinions on is_global.
One loopback address remains debated: Rust should also check if an IPv6 address is actually an IPv4 mapped to IPv6 and is loopback.
Rust differentiates unicast_link_local and IPv4 to IPv6 mapped addresses that are link local (in IPv4 definition).
