Well, the non-trivial percentage of large orgs that have literally run out of RFC 1918 space would disagree.

But yes, you're right. There's a weird Stockholm syndrome thing some people have with NAT.

Yes, companies run out of RFC 1918 addresses, but no, they will continue to use public ranges for their internal networks.

>vs a v4 network where you have no letters to work with

It'd be hard to have so many devices that even in 10.0.0.0/8, you run into a need to have letters as part of the network addresses.

My home network is larger than most and I while I use multiple subnets for fun, I could it all of it into a single /24.

It's not weird. Many ISPs have dynamic prefixes, and even with "just" 56 bits that prefix is long and not very memorable.

Thus ULA is a must on the inside, and DynDNS is still required for anything internet facing.

A more accurate way to describe this is that IPv4 prevents anyone who isn't a hobbyist or professional from running their own server.
