Re: redesign

"Why did they have to completely redesign the protocol for IPv6?"

As often discussed here: IPv4 has no repeat no mechanism for indicating a different address length, so switching to a new IP version number was obligatory. And (in 1994 when these decisions were taken) there were a lot of known gotchas in IPv4, so IPv6 was redesigned to avoid them. Now, of course, there are workarounds for those gotchas, so people don't notice them so much.
