America Runs Out of IPv4 Internet Addresses 435
FireFury03 writes: The BBC is reporting that the American Registry for Internet Numbers (ARIN) ran out of spare IP addresses yesterday. "Companies in North America should now accelerate their move to the latest version of the net's addressing system. Now Africa is the only region with any significant blocks of the older version 4 internet addresses available." A British networking company that supplies schools has done an analysis on how concerned IT managers should be. This comes almost exactly 3 years after Europe ran out.

IPv4 addresses seem to be going for about $8 to $9 at the moment, in blocks of 256 or larger. That makes a class-C allocation worth less than $2,500. So I doubt there's a crisis just yet.

Similar things have happened with phones and websites. When new area codes were introduced or new top level domains, a few people had problems accessing the new areas with older equipment if the older equipment was hardcoded somehow.
The stuff you are describing was initially contemplated, which is why we had IPv4 compatible addresses (::192.168.2.5) and IPv4 mapped addresses (::ffff:192.168.2.5).

You do know that the internet is routed in pools right? All you do by breaking up the bigger pools is further screw with the exponential growth of routing tables until it will all break, and it will break. That is one of the reasons IPv6 addresses are as long and contain as many bits as they do, whereas in reality to cover all devices we only needed to add a few bits to the existing system.
Don't break my internet.

I've been hearing from that impeding doom for about 10 years. In the meantime never have I seen one IPv6 implementation actually be used.
You have now. Here's IPv6 being used to vandalize Wikipedia! [wikipedia.org].

The impact here is for any new ISP--they'll have to offer IPv4 through NAT. While that will be a pain for a small number of uses, for the most part, it means it's a lot harder to track specific accesses back to a given account. Copyright trolls will hate this.
The biggest problem for regular use is providing remote access. If you're used to being able to ssh into your home system or run some remote desktop when away from home, having to go through NAT presents problems.

NATs are the biggest pain in the ass for every user, whether they know it or not. They have taken back the internet by decades. Not only are they full of bugs and incorrect protocol implementations, they have forced myriads of developers to spend thousands of hours on unreliable NAT hole punching hacks just to be able to use the internet for what it's intended to. In addition to this,they have frustrated and enraged millions of gamers.

They can't. For lots of legacy/legal reasons those organizations outright *own* those /8s, as opposed to just having been "assigned" or "allocated" to them.

The problem with this is that some of the original recipients of those really big blocks like GM and HP were given those addresses, not leased them. They, for all practical purposes, own that address space.
I know the organization I work for is a part of the problem. Before ARIN existed, a group of three schools (I work for one of them) were granted a /8 as a part of our research status. We have no relation with ARIN, and there isn't even a way to really give back 100 of the /16's we don't use.
Re: (Score:3)
Good. No really good. IP addresses are designed to be issued in blocks to networks with sub-blocks to be issued to groups within the networks. Not doing that results in bloat of the routing tables which are experiencing exponential growth and are already quite close to the point where things start breaking (due to the hardware limits of the size of some routing tables)
Splitting up a /8 into 100 other components and distributing them across different networks around the world is NOT a solution, or at least i

There's the equivalent of over 3000 full class Cs on the waiting list for supplying by ARIN right now. (OK, there are currently no requests for a class C as any request that could be satisfied by a class C was, until yesterday, being filled from the available pool)
Recently they got given (IIRC) a /15 and two /16 which were immediately filled from the waiting list.
The problem with giving you (and anybody else) a /28 is that unless it's aggregated at the ISP, the global routing tables are going to explode (th

Ah, four class Cs. That should satisfy demand for a good 2 minutes or so.
v4's problem isn't that parts of it are unused. It's that it's just too small. Returning little blocks here and there won't fix that.
