Ah, right, because we threw in hex. That's fair, but then I return to: If we're doing that, we should have changed the port separator.

  If it ain't broke!

    I contend that needing [] to disambiguate is absolutely broken.

  Using hex is probably a mistake. We didn’t use hex for IPv4 and that worked really well.

I wonder how many readers realized your joke here. For the ones who didn't, the 4-byte "magic number" that identifies Java .class files, in hex, spell "CAFEBABE".

  It's also just sort of generally used as easily spotted value in a hex editor. similar to DEADBEEF, ABADBABE, CAFED00D, and probably a bunch more variations on the concept. CAFEBABE seems especially prolific, getting used for -- among other things -- poison value for memory pools in plan9 and MACH-O universal object files magic number[0] [0] https://en.wikipedia.org/wiki/Hexspeak https://en.wikipedia.org/wiki/Hexspeak

reserve a TLD, like ".v6", and you are done. URL parsers don't break, the amount of code to change is not that big, and many of the user-space applications can keep working with no changes at all, as long as they use high-level network libraries. If you really hate this for some reason, use some other characters. How about underscores (_) for example? Those are not valid in DNS, so there is no chance of confusion. Choosing colon when URLs were already using it is either very stupid or very mean.

  There is the .arpa domain used for reverse lookups. ipv6.arpa is already used for that. But combining the ipv6-literal from Microsoft, gives ipv6-literal.arpa.

Dots and decimal, like 47806.51966.0.0.0.4919.57005.48879
