The IPv6 Numeric IP Format Is a Usability Problem
What is the rational reason, if any, for gripes like these?
The time to have this discussion would have been in like 1993 or so.  Now, IPv6 is what we have, and the standards are what they are, flaws and all.The only reason I can think of is psychological: People don’t want to learn new things, so they find reasons to dislike the new thing to be able to pretend they don’t need to learn it.Also, the double-click argument is crap for two reasons:  Firstly, it can be fixed by configuring your local software, and secondly, IPv4 addresses also had this so-called problem.> IPv6 is still in the early stages of adoptionIt really, really isn’t.  It might look that way to you, in the US, at your home endpoint, but move to the backbone or outside the US and you get a very different picture.  ARIN in the US just happened to be the last of the RIRs (except AFRINIC in Africa) to run out of IPv4 addresses, so the US was able to put off switching for longer than most, and the whole of the US is now consequently behind the curve.
