3/8 or 3.0.0.0/8 means the IP address range from 3.0.0.0 to 3.255.255.255 - this is 2^24 or 16.7M IP addresses.

Why does Amazon want it? - Amazon has a lot of customers who want EC2/ELB instances with their own IP addresses. IPv4 addresses are a scarce resource.

Why did GE have it? When the IPv4 address space was formed, various big US companies managed to get the initial IP address allocations. You can see more on these allocations here: https://en.wikipedia.org/wiki/List_of_assigned_/8_IPv4_addre...

Why so many upvotes? It's relatively rare to see what is 1/255th of the IPv4 address space sold.

Does that mean Amazon has a lease from ARIN on those batches of IPv4 addresses for a period of time (in the same sense as a domain registry for x years) or actually own them?

Also, That Wikipedia article was particularly helpful. I knew the /32 was specific to my IP that I use but didn't realize the sheer scale of those blocks.

IP Address purchases one-time purchases, you don't pay annual fees.

There is another comment here that said Amazon paid ~18/IP. They won't pay this next year.
