While I do agree with you, I do think we should be long past the point of needing to manually enter IP addresses. We have several good service discovery protocols, and DHCP and DNS, which are less great but still has pretty good tooling these days

I am using IPv6 on home network and I don’t know any addresses. Everything picks up the details and assigns address. To access hosts that matter, I use the mDNS names.

I think 1 IP address per human was short sighted. We ran out before the human population doubled. But I think a billion per human was someone liking powers of two, and nothing more. “Ipv5” with 48 bit addressing would have done pretty well. As 6 octets or 4 base 12. For humans you could reserve all values <=512 and >256 and have about 50k times as many addresses while people sort themselves out and still be able to see at a glance that they were ipv5 addresses. 1047.258.300.0/24

v4 was 32-bit, v6 was 128-bit. I think that 64 bits is a more obvious happy medium.

Conveniently, 2^13 = 8192 allows you to use most of the information available in four decimal digits. And 64 = 13•5 - 1 means that you get a roughly even division into five address tiers (with either the first or last one half the size). 4095.8191.8191.8191.8191 is a bit worse than 255.255.255.255 but not nearly as bad as ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff.

Slightly less annoying than 48 bits, too. Good points.

When I was in a phase of really enjoying IPv6, I went out and bought one of these: https://ipv6buddy.com

I don't type in many IPv6 addresses anymore, so this doesn't see much use anymore. It does make a great desk nicknack, though!
