Why is your Internal v6 subnet advertised to the Internet?

Because that was the example network -without- NAT. If I made two
networks -with- NAT, there would be no difference to show.

I make 2602:815:6000::/44 be 199.33.224.0/23, make 2602:815:6001::/64
be 199.33.224.0/24, make 2602:815:600::1 be 199.33.225.1 and make
2602:815:6001::4 be 199.33.224.4, it would be the exact same example
with the exact same network security impact.
