What Hacker News says?
I find this extremely hard to believe. EDIT: Just to clarify, AWS has a lot of IPs, over 100 million [1]. Let’s just speculate that 1/50th might be in an overall pool for customer allocation. Do you really think the majority of 2M IPs would come back blacklisted in some form? I haven’t dug in to this to actually see if this is the case, but it would seem laughable to even begin to think that this might be the case..…

HN discussionThe actual number is much higher. Amazon doesn’t publish all their IP addresses in that json, only the ones in use. They have almost double the IPv4 addresses, ie quite a bit reserved for future use. See https://toonk.io/aws-and-their-billions-in-ipv4-addresses/in...

HN discussionThere is no shortage of IPv4 address space. There is a problem with the government and private entities hoarding address space they don't need. Amazon alone is sitting on billions of IPv4 addresses. They've snarfed up /10's, /8's, and partial /8's: https://toonk.io/aws-and-their-billions-in-ipv4-addresses/in...

HN discussionWow, $43 per year, that's not cheap! It's likely the price AWS pays to acquire a single new IP at the current market price. Three years ago, they had about just over 100 Million IPv4 addresses, which at the estimated market price back then, would have been worth ~$2.5 billion worth of IPv4 addresses! https://toonk.io/aws-and-their-billions-in-ipv4-addresses/in...

HN discussioncorrect, 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.
