It's easier to remember the IPs of good DNSes, too.

Today in our newest take on "older technology is better": why NAT rules!
I can see that, but surely there wouldn't be much difference matching the first 4bits (0x2XXX, 0xfXXX) vs the first 16 (0x0001)?
0:: is presumably all for loopback-type stuff, but I don't see a reason not to use 1:: through 1fff:: and they would be much easier to type/remember/validate for public DNS servers which are needed before name resolution is available.
Not sure on the history of that. It would make things like that easier
