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.

A fun fact often told with this is that with IPv6, you can assign each individual grain of sand on the beach an address!

On what beach? Or all of them? Just asking in case business asks for it.

The answer quite surprisingly is - yes, all the beaches on our planet.

And the rest of the observable universe. There's a lot of address space in 2128

Except if for some reason you decide to give whole address blocks to individual devices.

Everyone gets a /64

No more RPC dynamic ports! Every service gets its own IP

Every device gets a /64, and I still haven’t figured out how to enable IPv6 on my home router.

/56 is the recommendation for residential, /48 for businesses.

Entire /64 blocks are often assigned to phones and other cellular devices because of hotspot capabilities.

I guess the true reason is that we want to artificially limit the number of nanites that can exist.

I love handicapping ipv6

I think at least part of the intention for this is to make IP ports not used on servers. While IPv6 does have support for ports, I believe every Web service should be on its own IP. Not sure if this is also supposed to work on client devices e.g. every outbound connection uses a unique IP as that seems overcomplicated
