> Like I own 8.8.8.8. You want to add more bits, fine, I'm 8.8.8.8.0.0.0.0 now. If anyone switches to the new thing, they know where to find me.
Yeah… from the above link:
"""
Incidentally, "IPv8" proponents often ask why IPv6 didn't simply stick some extra bits on the front of IPv4 addresses, instead of inventing a whole new format. Actually, we tried that: the "IPv4-Compatible IPv6 address" format was defined in [RFC3513] but deprecated by [RFC4291] because it turned out to be of no practical use for coexistence or transition. The related "IPv4-Mapped IPv6 address" format is still valid and has a role in the POSIX socket API. Mappings of this kind also figured in the moderately successful coexistence technologies known as 6to4 [RFC3056, RFC3068] and Teredo [RFC4380], which have now been overtaken by events.
The people who created IPv6 weren't stupid: if you think you've thought up of a new idea, you probably haven't. Your "new idea" is either in the exact same situation as IPv6 or it was actually attempted and ended up being discarded.
6to4 wasn't that. 8.8.8.8 didn't get routed to you in v6, instead it went to a relay server that then translated to v4 then sent it to you. And even if you actually owned 8.8.8.8, it didn't give you 8.8.8.8.1 etc, because it was just some bolt-on for transitioning from v4. I just want to own 8.8.8.8(.0.0.0.0) in v6 and that's it, not have my v6 actually be abcd::1234::...
I don't think they were dumb, they wanted to start with a clean slate and underestimated the difficulty.
