Why so many v4 block have been assigned to college or university?
In current circumstances, where there is a shortage of v4 and may be exhausted in near future, i am wondering why so many v4 blocks have been assigned to college(s) or university(ies), where they are not even using half of their allocated space. In general, do college(s) or university(ies) really needs these many ips? If internet registry really fears that v4 would be likely to be exhausted in near future (hearing this from 2 years), why don't they recover unused ip blocks from such institution?

Thanks to ARPANET.
My car has a flat tire, so I'll be taking one of yours.
ICANN could simply give out a memo that IPv4 is from now on deprecated and they will revoke every IPv4 space assigned in 5 years. Than you go IPv6 or offline. Problem solved.
Seems fair. I'll be assisting your task by increasing your lead diet. Studies show that most things that go through the stomach have a very minimal percentage that actually gets into the body, so we'll be introducing a more direct pathway.
It was once expected the universities would need so many addresses.
Unfortunately, one day, people started preferring becoming Viagra-buying moronic couch potatoes rather than digging into universal knowledge, hence the dramatic shortage of IPs experienced by the billions of spammers out there.
Wait until you find out that there are many public corporations that have an /8.
This is all a complete mystery. No one can figure it out. I'm sure the fact that they've had these allocations for 30 years and when they were made no one anticipated ipv4 shortage and there is a huge financial cost to renumbering and ipv6 is already here can't be the explanation.
So please report back when you find out the real story.
Because they could at that time and you can't just take things away from others without valid reasons. Lack of IPv4 isn't a valid reason since we do have IPv6.
Not many figured IPv4 would run out 20 years ago.
Some large early / legacy blocks are not under control of any RIR, but existed/grandfathered before ARIN, RIPE, etc existed.
They created the internet, more or less, and were the first in. MIT already returned a huge amount of space more or less out of goodwill.
It is useful though, I have some /18 and /17 from schools to use
Agreed. But then voluntarily, they can return back unused space!
Apparently, all of North Korea gets only a /22, which doesn't seem very fair.
Why would they? I wouldn't. They may be "unused" but could be used at any given moment.
They are probably being used for years now just laying around, the network is designed as such, and dropping a /24 would result in serious rearchitecturing, new whitelist problems, etc.
Universities and research centers were the first "implementing" the Internet, therefore they've been allocated larger amounts of space to cover their "future needs". Recall, at first RIRs / ICAAN have allocated space based on a Class A to C scheme - which ultimately means /8, /16 or /24.
I doubt that any RIR will ever force an university to give back portions of their space albeit used or not. IPv4 space has always and will always be invoked on the first-come-first-served principle. Your fault for being years too late. Get on the IPv6 train.
Indeed, why do they need a /22 for a whole of 5 devices!?
Such a waste of precious IPv4 addresses.
Should be worth noting that even if universities/governments/corporations let go of their large blocks, it would not solve the IPv4 shortage problem. Doing so would just kick the can further down the road as eventually those released blocks would be swallowed up and we'd find ourselves in the same position again.
That's the main reason why there hasn't been more pressure on these orgs to release their allocations. NAT is the short term solution. IPv6 is the long-term solution.
My toaster has a /32, IPv6 will last us forever.
I realize you're kidding, but apparently they have an internal network which is quite extensive. That /22 is just the part that overlaps with the external internet and which is only available to a few there. In any case, you may be interested in scans of that /22.
Ford, MIT and Apple all have /8s

Ford is also apparently looking at selling.
It looks like the person doing those scans got bored and stopped over three years ago. :-)
But, yes, no doubt, internally they must have another solution (NAT?).
They’re running an Intranet, so all their websites are within local ranges. It’s kind of sad really, because even the Intranet is only accessible to elites and university students down there.
One such potential usage is in the student housing complexes. Is wager many university student housing complexes give out IPs to residents vs NAT so as to better track back their usage. Same might be true for on campus university systems.
But I could be completely wrong about that
Many companies/universities are now realizing that they can sell their space, so there is a ton of it being sold. Most of it is being purchased by Microsoft, Amazon, and Google for their cloud services.
Oles was silent on Twitter, usually he came up every week and said, here look, another /16.
