Fwd: RFC 8369 on Internationalizing IPv6 Using 128-Bit Unicode

[Philippe Verdy via Unicode]

It's fun to consider the introdroduction (after emojis) of imojis, amojis,
umojis and omojis for individual people (or named pets), alien species
(E.T. wants to be able to call home with his own language and script !),
unknown things, and obfuscated entities. Also fun for new "trollface"
characters. In fact you could represent every individual or even single
atom in the universe that has ever created since the BingBang !

But unlike peoples and social entities, characters to encode don't grow
exponentially but still linearily at a slowing speed. Unicode characters
are not exploding like Internet addresses (organizations, users, computers,
phones: the IPv4 space expoloded only because the equipement rate of people
accelerated but now it is slowing down with high equipment replacement
rate, and only the explosion of IoT continues to drive some growth but it
will rapidly reach a cap, so even the IPv6 address space will never be
filled even if it will be much larger that the UCS encoding space; I can
expect a maximum in the range of ~300 billions devices at most with all
planet resources as global population will not be able to grow
exponentially and will necessarily cap, plus ~100 milions
services/organizations; all the rest will die and will be replaced and even
if we give a delay of 100 years before reusing addresses of died devices
and people in IPv6, this will leave lot of space, we'll never reach a small
fraction of the number of entities in the universe; we are also completely
unable to make any physical measurement with so many digits of precision:
even just 64 bit bit is really extremely large, but 128 bit was chosen in
IPv6 just to allow random allocation without needeing excessive centralized
management, an IPv6 address is even a good subtitute to the whole DNS
system and its overvalued black market of domain names: IPv6 is extremely
economic !)
