China To Run Out of IPv4 Addresses In 830 Days
JagsLive writes "China is running out of IP addresses unless it makes the switch to IPv6. According to the China Internet Network Information Center, under the current allocation speed, China's IPv4 address resources can only meet the demand of 830 more days and if no proper measures are taken by then, new Chinese netizens will not be able to gain normal access to the Internet. Li Kai, director in charge of the IP business for CNNIC's international department, says that if a netizen wants to get access to the Internet, an IP address will be necessary to analyze the domain name and view the pages. At present, most of the networks in China use IPv4 addresses. As a basic resource for the Internet, the IPv4 addresses are limited and 80% of the final allocation IP addresses have been used."
Try the whole world. According to this counter, the world will be out of IPv4 addresses in 768 days.
Sounds like it will be easier than ever to ring the Wong number!
Smivs on the intertubes!
Do any Chinese citizens even have "normal" 'net access now? Thought NAT was used heavily, not to mention the GFWOC
Don't blame me, I voted for Kodos
To get a quick infusion of 700 billion IP4 addresses -- NOW!
The dangers of knowledge trigger emotional distress in human beings.
When your WHOLE COUNTRY is behind a firewall? NAT the hell out of that! Flatten it to a /8 network in 10.0.0.0 and put it all behind one public IP. Problem solved!
Or will they just open up reserved addresses or something stupid like that?

C'mon HP, be a good netizen and give back the bulk of those IP addresses. Try using NAT instead of hoarding IP addresses that others so desperately need.
I predict that we'll see China begin to use IPv6 addresses before most other people. Why?
Granted, I'm no fan of China's human rights policies. But it definitely has an advantage in terms of adopting IPv6. Hopefully, when China switches protocols, it'll catalyze the rest of the world to do so as well.
Slashdot runs it's 15th story about IP addresses running out "real soon now". The first was something like 5 years ago :)
These stats ignore the fact that there are huge available allocations that can go behind NAT's. An ISP can NAT big chunks of its user network. Charging even a modest amount per IP would free up huge numbers of IPs. There are abandoned blocks (companies out of business) and wildly oversized blocks (MIT etc).
Plus, we've been hearing these stories for years. The idea that the internets resources are going to become ipv6 anytime soon is unlikly. So folks are going to figure out a way to manage the existing pool, where there is lots of room for improved efficiency.
Fun to keep on reading these stories... they're always written as breaking news :)
They're even running out of RFC 1918 addresses.
the LHC will end it quicker than that. They estimate some 90 days until they've got their repairs done ;)

Seriously their government is hell bent on controlling what goes into and out of that nation and what better way to do that than by forcing people to use a proxy..

IP4 doesn't have enough addresses, of course a managers solution is to put of the inevitable so that it happens on someone elses watch rather then taking the time we got now to develop and implement a solution.
IF pushing IP6 doesn't work in the roughly 2 years remaining THEN we can use the buffer of under-used blocks as a last reserve. if we use the reserves now, and do nothing then we still have the same problem, just a bit further away but this time with no reserves remaining and no work chance of it being solves in time.

NAT is not a solution. It's a huge, gigantic clusterfuck of a problem. Some people only started their careers after NAT was widespread, so they can't imagine how wonderful the world is without it. The internet is much simpler when you can assume that all nodes can directly address all other nodes.
Look: this is what we've done.
In the beginning, each endpoint of a TCP (or UDP) connection looked like this:
[octet][octet][octet][octet][16-bit port]
[(------- host-------------)(--service--)
Each octet was routed hierarchically, and the port acted as an additional level of routing within a single node.
With CIDR, the model moved to this:
[32-bit opaque address][16-bit port]
(-------host----------)(--service--)
This change didn't hurt anything, aside from an increase in router complexity. Allowed the 32-bit address space to be used much more efficiently.
Now with the IP address shortage, the situation looks like this:
[48-bit address]
(----?---------)
Note how we've lost the distinction between host and service and smushed them all together into one huge opaque number. We've caused ourself lots of problems with this:
These days, instead of saying "connect to mydomain.foo.cx", for example, you have to say "connect to mydomain.foo.cx at port 12345". That's out of band address information, and should never be needed. Imagine if DNS only gave you the first three octets an IP address, and every application requires you type in the last one in manually. That's what the world is like today!
Heck, they already firewall everybody -- why not just break IPs up into NATted subnets? The 10.x.x.x range should give them enough room for awhile, right?
Hmm.... 16,777,216 IP addresses divided by 1,300,000,000 citizens.....
I want peace on earth and goodwill toward man.
We are the United States Government! We don't do that sort of thing.
So the world runs out of addresses before China runs out?
The world will run out of new blocks to allocate (as in "254.xxx.yyy.zzz"), before China gives out all addresses in the allocated blocks it has (as in "www.254.254.254").
Nonetheless, IPv4 can only provide a little lower than 253^4 different addresses. What makes it worse is that it's allocated in chunks (some chunks are reserved like the 127.x.y.z family - other addresses may be free but land in a range which is allocated to some company and thus can't be used by your computer).
Thus even if some providers use dynamic IP (only those machine which are connected have an IP address - thus an ISP needs a chunk only as big as the number of simultaneously connected users, not as the total number of subscriber), and lot of router use NAT (only 1 single IP address is visible on ther internet. all the machine are visible through this address and use a private address on the internal network),
in a world where everything including your fridge is connected to teh interweb 24h a day, 7 days a week, we will quickly run into a situation where no more IPv4 address can be assigned to a new machine :
- the ISP has ran out of addresses in its chunk because there are more simultaneous connection (because everyone stays perpetually connected) that there are free address in the chunk (china will reach this point in 2-3 years)
- and there are no more new free chunk to allocate for the providers (all are already either reserved like the 10.*.*.* and 192.168.*.* range, or have already been allocated to others) thus now way to give more chunks with more IP to the ISPs (the world will reach that point too in about 2 years).

Why is everyone in the comments talking about various steps (reallocating large blocks, more widespread NAT, etc.) that would allow us to push back IPv6?
It seems that we very close to the point where every device supports IPv6 (Vista adoption is helping this) but just isn't using it. Let's start turning it on. What better way to help the adoption than by having users who are IPv6 only complaining?

We've only used half the available numbers.
Just start using negative numbers: -248.100.-97.-201
Cress, cress, lovely lovely cress
Quite so. It's simply good netiquette.
Peak IP4 is a myth; there are still plenty of addresses buried in the Canadian tar sands. However, in the short term, the only solution is to lift the ban on coastal drilling for IP4 addresses.
I'll answer your question with another:
Why not?
Seriously. This whole "X doesn't NEED to be on the internet" is a ridiculous argument. It's simply saying "oh, having a PC and computer type equipment on the internet should be enough for anybody". The whole point of this internet thing is innovation. Sure, a fridge doesn't NEED to be on the internet. Unless I want it to have some functionality that requires internet connectivity. Same with my computer. It functions just fine, and doesn't NEED to be on the internet.
And why is "fridge can reorder beer for you" drivel? Is there some reason that a fridge SHOULDN'T reorder your beer? Sure, it's not a vital function, but neither most of the stuff that our technology does. Again, this is what innovation and technology is all about - improving the standard of living, making this easier, etc.

As much as technology will allow.
