In elaborate terms: you have the ability to change any one of the protocols, specifications, designs or standards of the above at their proposal stage or before their mass adoption. You may choose to modify or reject an existing one or create one by yourself.
Some users and I would have common ideas in mind, however I would love to see some esoteric ideas as well.


Stop IPv6 from existing.
Make IPv5, add a fifth number to the address, and improve NAT.
Not every particle in the universe needs a publicly routable address.
That’s interesting - I hadn’t heard too much dissatisfaction with IPv6 before, except for the slow adoption, and the not-as-nice looking addresses. Is it an aesthetic preference or just that IPv6 is overkill? Or any other advantages to doing it the “IPv5” way?
This is a pretty good takedown of IPv6 but I think the biggest problem with its adoption is the addresses. They look like gobbledygook just so we can give everything a public address and it made it a lot more fiddly to configure.
Giving everything a public address was the original intent! NAT didn’t even exist prior to '94 and it was (and is) a massive kludge.
oh god, the nightmare that “adding a fifth number” would be
It would be less of a nightmare than changing all our addresses to add four more sets, be alphanumeric, and to change the separator.
The design team flew too close to the sun with that.
