How does aws manage public IPv4 addresses allocation
And yeah, this means lots of EC2 instances have their own IP address. This is why AWS hash over 74 million public IPv4 addresses, and why the mass majority of them, something like 75%, are used for EC2.

Amazon, Verizon found using IPv4 240/4 addresses
> Moreover, we did not find any 240/4 prefix in the official prefix list shared by Amazon
Yeah, so about that:
https://github.com/seligman/aws-ip-ranges/commit/2e0d9d87d4f...
They did briefly list 252.0.0.0/10 in their published list of IP ranges. The people I spoke with about this at the time either claimed it was a mistake, or the state of the world that I should get used to (it broke some surprisingly fragile scripts on my side for silly reasons).
Given they removed it from their list of IPs 27 hours later, I'm guessing I wasn't the only person freaking out. But yeah, they use it internally, and it leaks from time to time in surprising ways.

AWS running out of IPs?
They have north of 66 million IP addresses, so if they're running out, that's an impressive feat.

[OC] Amazon's AWS size based off IP allocation
This is sourced from a document that AWS publishes, called ip-ranges.json, as archived in my GitHub repo, with a little help from the Internet Archive's Wayback Machine for the first year or so of data before I was archiving changes via a script.

AWS just bought 5.5 Million IP addresses
