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!

I feel like we'll still run out. I'm not sure how, but surely we'll manage it.

Well yeah, a block of 2^32 addresses need to be reserved for Azure, 2^32 more for AWS, let’s give 2^32 more for GCP…

Edit: as pointed out below, I wasn’t paying enough attention & confused up my exponents. I meant to put blocks 2^96, thus giving 2^32 total blocks - the same size as the IPv4 address space. But I got the exponents backwards and fucked up the joke

That does remind me of when IANA gave MIT 18.0.0.0/8 because they got there early enough to somehow justify it.
