Amazon bought half of the 18. space from MIT in 2017. I remember having to change IPs on servers. The price was a significant amount. Amazon is finally getting around to monetizing this scarce resource. Go capitalism.
I remember around 20 years ago, I was working for a small consulting firm here in Jacksonville, that housed servers for small businesses, in the “upgraded” facility, a/c, security, power, etc.
Back then we had an entire class C /24 address space of public IP addresses, someone wanted to run their own email server, web server, etc., and need a public IP address, we provided that for a monthly cost, we setup a DNS server that hosted their records if necessary.
That’s why I was curious what AWS wasn’t charging up until for that service.
