I’ve often wondered if going with 64-bit addresses with a dotted quad hex notation would have eased the roll-out. I remember a lot of resistance when IPv6 was first announced along the lines of “I can’t memorize/type in giant addresses and I don’t want to have to use DHCP and DNS everywhere.” It felt like IPv6 never recovered from a bad first impression.

I'm not sure I've ever heard this view expressed by serious, competent network engineers. I have heard it a lot from the home hobbyist though, but I'm not sure how much that demographic matters in the grand scheme of things.

Serious, competent network engineers are not created in vacuum from platonic ideals and TCP fragments. They're home hobbyists who grew up hating ipv6, and won't magically learn it overnight when their previous networking guy quits and they get handed the keys to the server cage

These people are neither competent nor serious.

In the real world, people who design and operate large networks are the very same people who staffed the working groups who designed IPv6. It's their design.

A key aspect of IPv6 is that the address space is big enough that 'carving it up' for subnets is dramatically simpler even at the largest scales. You don't need to be frugal with network sizes, and you don't need central coordination to avoid conflicts. This is huge!

E.g.: If I want to deploy a cloud VPC (or vNET), then I have to go find "the guy with the spreadsheet" and peel off a tiny(!) private IPv4 address space. If he's away from his desk or on holidays, my 1-minute automation script will now take 1-10 working days until he's back and responding to requests. With IPv6 this just disappears as a bottleneck.

"IPv6 is great and easy to use, if you're one of the leading experts who designed it"

This is not the kind of glowing endorsement you think it is, if you're expecting your technology to see widespread adoption

Half the US has already deployed it and 100% of the mobile carriers. I would say the detractors who continue to stomp their feet about not deploying IPv6 are holding a fake title of "Network Engineer". People need to grow up and do their job or get out.
