Thank you. Now imagine its 3AM, you haven't had ANY coffee yet, and they are screaming at you that parts of the network aren't working. Quick, could you look at a whole pile of IPV6 numbers in a list and spot which ones don't conform? Bet most can't because our brains just don't process hexadecimal nearly as well as it does numbers. But if they gave you that same list in IPV4 octets you'd spot the 194. numbers in less than 3 seconds.
Hell they could have gone to 7 or 8 and it would have still been easy, because triplets are easy for us humans to whip off, just like "the phone number song" where people got dot, dot dot duh, dot dot duh, dot dot duh duh. Instead what we got is over done, needlessly complicated, and obviously done by engineers that haven't spent a day in the field. Hell how many years did they scream "You don't need that!" when it came to NAT and DHCP? I remember the first couple of years they screamed up and down "Just give everything its own public IP!", yeah, like THAT won't be a security nightmare, nope, what could go wrong?
I'm just glad I'm out of corporate IT, I'd hate to try to install this giant clusterfuck onto some large corporation and troubleshoot the mess, what a nightmare! Oh and look at how the other posters argue up and down that humans will have NO problem reading hex just as easily as octets, I bet these same ubernerds walk around with binary watches and wonder why everyone looks at them as weirdos. Whether they choose to accept it or not the brain processes numbers and letters differently and most are MUCH better at counting in decimal numbers, that is just how humans work.
