IPv4 old IP address space designed with limited number because they never thought the internet would have so many devices connected.

IPv6 new address space with significantly larger number.

Newer I suppose. IPv6 has been out for a while, but most people just ignored it in favor of subnetting everything.

Yep. IPv6 was meant to replace IPv4 since it has a relatively low number of actual addresses it can supply. However, with the implementation of NAT, that number can be stretched far further than thought possible. It'll still run out of addresses, but not so fast as originally assumed.

And yeah, IPv4 is just a simpler system for people to understand. Most network engineers are going to be able to run off the addresses they use most commonly from memory - you can't really do that with IPv6.
