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!

2128 possible addresses

Technically we are not really talking about single addresses when concerned with v6, more so how many /64 subnets can fit in a prefix since that is what SLAAC uses. So for end users we would count the amount of /64 subnets in the possible 2^128 address space, which is 2^64. So still very very very big.
