No traces of this block in the public Internet doesn't mean it isn't being used. It may be in use in some internal network(s) instead of a private address range (yes, that happens).
Hooray, another /8, that'll last us for a good month or so. Exponential growth people, reclaiming unused IP blocks isn't going to stop it. And that's ignoring the possibilities that a) it's being used internally by its legitimate owners b) it's being used internally by other people. T-Mobile were seen to be (mis)using the /8 that belongs to the UK MOD for their internal networks, I wouldn't be surprised if they were…
Do you have an idea of how many IPv4 addresses that are unused or not really needed? Between the bunch MIT got, the bunch that the military got and the bunch that IBM got, we can implement an entirely new protocol before we run out.
When Apple and MIT got their allocations it probably seemed pretty reasonable at the time. "How many organizations like that would be interested in the internet? A dozen? That sounds about right."
There was a time where anyone with a .net domain name would be able to apply for and probably get a /16 allocation with hardly any questions asked.
Eventually in the future, people will come to realize the over-exaggeration of running out of ipv4 addresses. The unused blocks will come out of woodwork from everywhere. Well, I hope my opinion is wrong.
By future do you mean right now where NAT is being used by some providers already? I know Rogers in Canada has all mobile devices going through NAT unless you pay a nice "VPN" fee. Also the assigned but unused IPv4 blocks don't do anything for other providers that actually need addresses.
I'm not sure about the definition of 'unused', just because a network is not visible from the Internet and has no publicly registered ASNs doesn't mean its numbers are not in private use (which AFAIK, was always a legitimate use-case for getting an allocation, and in many ways preferable to reusing RFC1918 space). Added to that, even if it was seeing only minuscule internal use, the UK government's IT project reputat…
We just got audited for RIPE for exactly this reason, and they made us specify details for all of the networks we use on our allocation to be allowed to keep our address space.
Amateur radio also has an unused IPv4 /8 block as well. That $500 mil could go quite a ways towards building a few amsats.

There's still a finite number of IP addresses that is below all reasonable expectations for how many devices will be wanting an IP address. Reclaiming unused blocks just softens the shock by making the exhaustion less sudden and more gradual. We're still definitely going to run out.
Even Comcast supports IPv6.

That being said, here is a list of people in charge of allocations: http://www.ampr.org/oldsite/amprnets.txt

Once no more unused addresses turn up, they can start economizing on the used ones too. For example my university gives a publicly routed IP address to EVERY computer, even though most are completely firewalled off.
Even if they were to start announcing them or selling them it would be a HUGE project for IBM internally to make sure that their computers aren't going out on the web for internal resources, and it becomes an huge issue of having to renumber.
Unfortunately there is no good way to support something like that. Some companies didn't need to use the private LAN addresses because they had their own /8 and changing it now would require too much effort and work.
