Shameless plug: https://billpg.com/sixgate/
(Short version: IPv6-only networks can provide a gateway for IPv4-only clients and advertise it via reverse DNS.)
SixGate has an interesting contrast with this RFC. RFC8950 removes IPv4 from the network core while preserving IPv4 reachability, whereas SixGate removes IPv4 from the service side while preserving reachability for IPv4-only clients.
In both cases, IPv4 survives as a compatibility layer rather than a fundamental requirement. The difference is that RFC8950 is aimed at network operators, while SixGate is aimed at the last remaining IPv4-only users.
In both cases, the goal is the same. Turn IPv4 from a requirement into an optional compatibility feature.

I once developed for PC-GEOS, which wanted all memory in exactly 8K sized blocks. I wrote a set of C macros that presented an array-of-arrays as a single collection by using mod/divide operations on the index.

I've reviewed what I originally wrote and I prefer the text I published. Sure, I could review it all myself (indeed I used to) but that takes time and it was becoming a barrier to actually publishing stuff. Maybe I'd have got around to finishing it in a few months.
I don't use AI to write for me. I hate people who do that.

I kinda wish they had. 64k windows with no overlap would make segment registers a slightly inconvenient 32-bit address register.
I get why hey didn't. Someone might want to run two processes each with its own segment, but the whole machine might only have 64k in total.

Hi. I wrote it, and I'm a human. (Or at least I think I am.)
I did use an AI for spell-checking, punctuation, generally making it flow, but its all my text.
You think a machine is going to come up with "near pointers, far pointers, wherever-you-are pointers"?

1992-author (me) is wondering if he'll ever get a girlfriend.
(And I completely agree.)

Why would you ever want a single 64k object? That's like an entire machine's worth of memory!
