Wow. This is a significant slice of the IPv4 address space, and one of the few remaining uninterrupted /8s owned by the private sector. This is a 10-year old visualization, but it's still a good one to visualize the scale of this purchase.

It's a great purchase for them, and a shot at Azure and GCP - Amazon can now legitimately tell larger clients "we will have enough IPv4 space to be your partner for all your static-IP-dependent applications, no matter how much you need to scale."
- ghaff 8y agoThey also previously bought half(?) of MIT's /8.

- jandrese 8y agoIt's really incredible how so many non-tech companies have /8s still. What is Prudential doing with all of that address space? Eli Lily?!? Who the hell is Cap Debis?
- trynewideas 8y ago> Who the hell is Cap Debis? Debis = Daimler-Benz InterServices, sold to T-Mobile (specifically T-Services) in the early 2000s CAP Debis was a partnership with CAP Gemini. Today it's mostly enterprise telecom/IT, though that maybe oversimplifies things. It's a big beast in Europe, Germany specifically.
- jandrese 8y agoI guess that one makes sense. I was having little luck Googling that name.
- nashashmi 8y agoI wonder if T-mobile is aware of that purchase. Sometimes these little known assets get lost by the big predator because they were interested in something very specific of the prey company.
- netopexcept 8y agoI'm sure TMobile is intimately familiar with their networking assets. They pioneered squatting on MoD space for internal routing to avoid dual homed conflicts.

- ancarda 8y agoIs there an up to date version of this? I wouldn't mind getting a poster of this on my wall.
- ericsoderstrom 8y agoWould love to see a more up-to-date version of this. I know MIT sold [1] a bunch of its address space not too long ago. [1]: https://www.internetsociety.org/blog/2017/05/mit-goes-on-ipv4-selling-spree/ https://www.internetsociety.org/blog/2017/05/mit-goes-on-ipv...
- ponytech 8y agoHow come there are still unallocated spaces with the lack of free IPV4 addresses?
- detaro 8y agoIt's from October 2007.
- walkingolof 8y ago" no matter how much you need to scale." Sure its a big block, but its still "only" ~16 million addresses
- natestemen 8y agoanyone have any good explanations of the image linked? like what are ARIN, RIPE, why is some unallocated, what is multicast? that sort of thing would be cool to learn
- pacificmint 8y agoARIN and RIPE are two of the five regional internet registries: AFRINIC: African Network Information Center ARIN: American Registry for Internet Numbers APNIC: Asia-Pacific Network Information Centre LACNIC: Latin America and Caribbean Network Information Centre RIPE: Réseaux IP Européens
- merb 8y agomulticast is like a broadcast except that it is authenticated, i.e each device that is authenticated against a certain multicast will get the content. it's mostly used for internet television or other multimedia stuff. (some stuff is/was unallocated, since some early users tought it's a good idea to actually use some unallocated stuff to do bgp..., testing or routing per se (especially cisco routers) or even login pages, exist nodes, i.e. 1.0.0.0 was a problematic ip, but since cloudflare grabbed the 1.1.1.1 I think people will stop doing stupid things)
- sofaofthedamned 8y agoIt's nothing to do with authentication, it's simply indicating you want the data. If authentication or encryption is used it's nothing to do with multicast.
- tialaramex 8y agoUnicast is sending messages to a single peer. Broadcast is sending messages to everybody. Multicast is in between, sending to some arbitrary set of recipients. On a Local network, multicast is very easy to do. Unless it's very, very old your computer almost certainly uses multicast on local networks already, for a variety of purposes. A dumb old network just sent all packets to all computers on the local network, so both broadcast and multicast were equally easy to do, your network card has a filter built into it, that autonomously weeds out messages your computer cares about, and ignores the others - so the Operating system is like "Hey, network card, my unicast address is 10.20.30.40, and I am also listening to multicast address 224.0.0.251" and it will just throw away any packets that aren't for those addresses. A smart modern network (e.g. the mid-range gigabit switch serving your desk at work) keeps track of which addresses are where and sends copies of messages only to where they seem useful, leaving more network bandwidth for everybody else. The Internet can in theory do Multicast too. I've used this to, for example, watch television with a dozen other people without any copy of the TV picture data being sent over the shared data link to us more than once. That's what those addresses are for, you "Join" one of the multicast addresses and begin receiving, say, the Olympics live. However making all this work is hard, and in most places, most of the time, nobody puts in all that hard work, so probably you'll find that although local network multicast works for you (as I said it's used in modern systems) you cannot use the Internet's multicast features. Which is a shame, but we can't have nice things.
