Do dorms have IPv6? If students can’t run servers, where does the next generation of developers come from?
I tried running a Pi in my college dorm. First, it was NAT, and when I requested a public IP, IT said they didn't give IPs to students. :/ IPv6 would be cool.

But the point is that they're not using it. If it's not addressable from the internet, why not use 10.0.0.0/8 instead?
Here's a little different approach to the issue: because IBM is using IP addresses the way they were intended. Private IP ranges are not a good thing, they are a necessary evil. NAT was developed as essentially a hack, originally more to solve tricky routing situations, but later more to allow broad use of reserved range IPs. But the original intent was always that all hosts would have a unique address, regardless of…
Well, no. The word "Internet" is short for "Inter-network exchange".
The original idea of the internet was to allow LANs to talk to each other. Not to give every single device on Earth its own unique key.

Well, I’m entirely willing to believe the US DoD is one of the few entities that have more than 2^23 computers they want to be mutually addressable, so the RFC 1918 space is just too small for them if they are to run IPv4.
DoD has 8 million computers? It's not like it's all government branches combined. In fact - DoD should just have it's own internet - that is completely separate. I'd argue that DoD networks should not have any connectivity with broader internet, making their use of the whole 32 bit space completely independent from everyone else.

IBM was the original "cloud"... AKA mainframes. They had a LOT of addressed services for decades (still do). If you want to pick on a company for hogging IPv4 space, pick on Apple. They have a /8 and probably aren't using any of it.
> If you want to pick on a company for hogging IPv4 space, pick on Apple. They have a /8 and probably aren't using any of it. Most (if not all) of Apple's infrastructure uses their /8 block. With Apple Park they've moved to using a 10/8 with NAT for talking to the outside. Between iCloud, iTMS/App Store, and iMessage Apple's got a non-trivial amount of global network infrastructure beyond just their corporate network…
The whole migration to IPv6 reminds me of DECnet migration to OSI…which basically never truly happened (because XNS/ITP grew up and became TCP/IP which was then extended to the edge with PPP/RAS, ending the era of store-and-forward email/usenet and destroying X.25/X.PC with its distance-based pricing, heralding the new era of free SPAM and Script Kiddies From Overseas). Same thing will happen to TCP/IP..something else will succeed it before IPv4 is obsolete, probably after somethingBad(TM) happens to create the market imperative for network operators to invest in the alternative.

I don't know about everyone else, but when I want to go to Hacker News I go to https://209.216.230.240 and ignore the security warnings of mismatched name. Way easier to remember than news.ycombinator.com, its five fewer characters!
I am a little ashamed to admit this, but I can't remember the URL for Hacker News and always have to search for it in Google if I am on a device that doesn't have it bookmarked. Somehow I still remember other long URL's like http://altavista.digital.com though.

That'd essentially mean that any DoD computer can never communicate with anything on the standard internet.
Doesn't mean that DoD cannot use the global internet, just not use it and their own at the same time. I mean... They could even send traffic over global lines, without taking up IP addresses.

We have run out of freely allocatable IPv4 and equipment isn't catching up to IPv6 - it's very relevant here. Neither Apple, not IBM, actually need that many publicly useful set of IPs. IBM would be smart to sell them off. Apple is probably going to sit on them. (I used to work at IBM and that 9 block was very confusing to me, considering that IBM isn't even that big of a DC operator these days)
> equipment isn't catching up to IPv6 It's not equipment...it's purely a financial business decision that this hasn't happened yet.
