First, an RFC 1918 address indicates that you're probably behind an
address translator. It does not prove that other computers on the local
network are friendly. You might be on a public hotspot surrounded by
potentially hostile strangers.

And this is worse than what we currently have where everything is considered friendly? this proposal is protecting situations when the IP address is known to be public.


Second, a solution that works only for IPv4 is not a solution in the
year 2019. You need to take IPv6 seriously, or you won't be taken
seriously.

It is my understanding that this is a mailing list where suggestions could be made, without insinuating some kind of bad faith. I explicitly stated "some other consideration should be done for IPv6" because in my country ISPs providing IPv6 are a dream, so I have no way to test or propose a solution I couldn't try on a real scenario.
