correct, direct url is https://toonk.io/aws-ipv4-estate-now-worth-4-5-billion/index... More interestingly, perhaps, is a forward look at how much new revenue AWS will generate once AWS starts charging ($44 per IP per year) as of 2024. I think it's not unlikely that AWS will generate a few hundred million to a billion in additional revenue with this new charge.

I suppose a sufficiently motivated individual could look at something like Shodan, see how many of those IP addresses AWS owns are active (and fudge it by some factor to account for how many of those IP addresses are used by AWS themselves) and multiply it by their new IP address billing.

No need to use Shodan. AWS already publishes the IPv4 address it owns in JSON from a well-known endpoint [0].

[0]: https://ip-ranges.amazonaws.com/ip-ranges.json

AWS does not publish what IPs are active and assigned IE: customers are paying for vs. addresses they own.

Hetzner charges 2€ per month or so for a v4 address already (optional of course).

That is for dedicated servers and additional IPs. The first on a VPS is 0,60€
