More on China's IPv6 Network Buildout
photojournaliste writes "China has developed and demonstrated its first high-performance network core router based on the next-generation Internet standard known as IPv6, which the country officially inaugurated earlier this week." There's also a CNet story, which has a bit more information than our earlier story.
From the news.com article
By increasing this to 128 bits, IPv6 provides billions more IP addresses
Billions? Try 3.4 dodecillion
From the article:
China is not the only Asian country with a strong interest in IPv6. Japan has already implemented an IPv6 production network, which is used by every service provider in the country. South Korea is working with the EU to develop applications and services using IPv6.

Hitachi GST sues Chinese disk drive maker
HONG KONG, Dec 29 (Reuters) - The hard disk drive manufacturing joint venture between Hitachi Ltd. and IBM said on Wednesday it has sued Chinese firm Magicstor Inc., saying it had made multiple patent infringements.
In the suit filed in United States District Court, Hitachi Global Storage Technologies seeks monetary damages and a permanent injunction barring Magicstor from making and selling the allegedly infringing products.
A spokeswoman at Magicstor, located in the interior Chinese city of Guiyang, had no immediate comment.
The suit names Magicstor, its Chinese parent company, GS Magic Inc. and California-based Riospring Inc., according to a statement released by Hitachi GST.
According to its Web site, GS Magicstor is a hard disk drive maker that was founded in 2002 "as the first small form factor manufacturer with its own intellectual property rights."
The filing of patent infringement lawsuits in the United States against Chinese firms has become a relatively common strategy by plaintiffs wary of using China's fledgling patent protection system.
Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC) the world's biggest contract maker of semiconductor chips, is using the tactic in its lawsuit against Shanghai-based rival Semiconductor Manufacturing International Corp. (SMIC)
Last year, Cisco Systems , the world's biggest maker of routers and switches used in telecoms networks, also used a U.S.-based lawsuit when it accused Huawei Technologies, China's largest telecoms equipment maker, of copyright infringement.

I used one of these to demonstrate to the IT department of my megacorp exactally why my networking lab needed it's own isolated subnet on its own Cat6K, and its own servers.
Once I started pumping out thousands of frames per second of random IP and MAC addresses their routers started dying under the loads.
I got everything I asked for

I *want* to be able to connect to any of my home machines from work, and vice-versa. NAT and port forwarding take care o this already. Most companies DON'T wan any machine to be publicly accesible.
There is a rather better article on the subject of IPV6 adoption at InternetWeek, but that article is now four years old.
As for the specific information in the article,
"IPv6 provides billions more IP addresses" - I think the reporter is a bit confused about all these large numbers. IPv6 provides billions of TIMES more addresses. More even than that in fact; 2 to the power 128 is 79228162514264337593543950336 times greater than 2 to the power 32. (This calculation was brought to you by GNU bc)
"It was created and deployed in response to ... especially as Web use in Asia rises sharply." - The author has fallen for the post hoc ergo propter hoc fallacy. In any case, the beginning of the development of IPv6 occurred significantly before the extensive takeup of Internet technologies in Asia.
As other people have already mentioned (including in the reader comments below the article - I would have contributed but see no point in "registering" with CNET), goodness knows where the journalist got their figure of "257 nodes". They should perhaps take the time to either check their notes or cross-check the information their sources are giving them.
Something the author failed to point out is that it is not only Asian countries that have been working with IPV6. There has been significant piloting in most countries that make use of the Internet. This means that there are IPV6 over IPv4 tunneling facilities that work therse days, meaning that it is not necessary for countries up upgrade everything to IPv6 in order for their businesses to trade with China, no matter what the article implies.
I *want* to be able to connect to any of my home machines from work, and vice-versa (firewall permitting). I would *love* to have my own block of portable address space for me to do with as I please.
IPs were never meant to be portable. Making it portable really messes up routing. This is why you set up DNS so you can name each device. I have a DHCP server that gives out IPs based on MAC addresses so all I have to remember is a name, not a long number (IPv6 numbers are a lot longer too).
Apparently, YOU HAVE NO IDEA WHAT YOU'RE TALKING ABOUT.
...and you call yourself networkBoy.

OK I'm a network engineer been one for 15 years. IPv6 does not make customer address space portable, it does make it easier to "renumber" but in no way does it even help multi homing. So you IP's from your provider are no more portable actualy since the rules for getting IPv6 space are harder pretty much anybody withou an AS does not qualify and there are 16 bits of those half of them allready used. v6 only deals with multicast and IP space as it's big wins. Funny the telco's dont want Multicast to work and the IP space thing isn't hurting anybody yet you can get all the space you can justify and pay for.
:) but most people dont qualify for a /19 and dont have 2.5k to buy the block.
BTW I can do what you described with NAT and with Public IP space (yes I have a public Class C in my home
No sir I dont like it.
Contrary to what many people know...there are MANY networks that are IPv6 enabled. Just not many IPv6 apps.
ALL of abiline (Internet2) is v6 enabled, just not all the way to clients.
Here is an up to date map of deployment of Ipv6 on I2.

Bzzzt... There is actually an addressing protocol built into IPv6 known as "Mobile IPv6" which allows a machine on the home network, listening for packets addressed to one of your "mobile IP's" will respond with a packet that tells the sender where to find that computer right now, a "care-of address."
This all requires the mobile computer to report back periodically with status updates on its current "care-of IP", and that's all. This is not a tunnel, it's real mobile IP, built into the protocol. I believe this feature is also available for IPv4 through use of some extension to the protocol.
Restating the obvious since nineteen aught five.
