An updated list of MIT's IPv4 address ownership:

https://whois.arin.net/rest/net/NET-18-0-0-0-1.html

So they don't have 18.0.0.0/8, but they do have 18.0.0.0/9?

That's up to 8388608 addresses lost...

Sold, probably. Looking at https://www.leadertelecom.biz/ips/transfer, that could have brought in a nice sum of money (they ask #unicode code points in dollars per 65,536 addresses)

Could someone explain this? I feel like I'm missing something (not the 2^16 addresses, the "#unicode code points")

There are 1,114,112 Unicode code points (17 times 64k), and that particular site happens to charge $17/IP, so for 64k IPs they happen to charge $1,114,112. Same idea as "number of libraries of Congress" or "number of Empire State Buildings", but nerdier.

Thanks! That was very helpful.

edit: From wikipedia:

"Unicode comprises 1,114,112 code points in the range 0x0 to 0x10FFFF. The Unicode code space is divided into seventeen planes (the basic multilingual plane, and 16 supplementary planes), each with 65,536 (= 216) code points."

Probably easier to just look at BGP

Ah, it looks like BGP caught up. Yesterday AS3 was still announcing 18.0.0.0/8.

Why'd they get of them in such odd intervals?

Well, I think some of the intervals are still actively used by building networks!
