alt Hacker NewsCirca 1999 I was working for Cisco as a sysadmin. I got my CCNP through internal training and considered making a career of network administration, but ipv6 changed my mind. It seemed so much more difficult and unpleasant to deal with. I didn't want that to be my day to day work.
I think the same thing happens on a different scale with ISPs. They don't want to deal with it until they have to for largely the same reason.

At first I though so too but IPv6 is actually easier. instead of CIDR you always have 64 bits for network and 64 for host. You get a public /48 IPv6 prefix that allows for 16 bits of subnets and then the host addresses can just start at 1 if you really want. So addresses can be prefix_1_1 if you want. And the prefix is easy to memorize since it never changes.
I DO think using 64 bits for hosts was stupid but oh well.

In my experience it’s much easier and much more pleasant do deal with. Every VLAN is a /64 exactly. Subnetting? Just increment on a nibble boundary. Every character can be split 16 ways. It’s trivial.
You don’t even need to use a subnet calculator for v6, because you can literally do that in your head.
Network of 2a06:a003:1234:5678::555a:bcd7/64? Easy - the first 4 octets.
Network of 10.254.158.58/27? Your cheapest shotgun and one shell please.
