IPv6 will help advert a shortage of network gateway addresses

If the internet survives the SOPA menace, it will be on its way to its biggest transition in decades on June 6, 2012.  That's World IPv6 Launch Day, a day where many of the internet’s largest sites will switch over to the new 128-bit address scheme.

Currently IP addresses use 32 bits, which works out to about 4.3 billion unique addresses.  To combat the growing address shortage, network firms developed network address translation (NAT) techniques, which simply reassigned addresses on a local network to internal IPs and routed packets accordingly.  The new limit thus became 4.3 billion unique gateways to the main internet, as local networks would not have enough machines to run out of IP addresses.

Still the problem remained so the in the late 1990s the Internet Engineering Task Force (IETF) set to work making the replacement to IPv4 -- 32-bit IP addresses.  In 1998 they published RFC 2460, the 128-bit standard that would come to be known as IPv6.

By 2008, though, few had adopted the solution with less than 1 percent of internet traffic going through IPv6.

But necessity is the mother of invention and Google Inc. (GOOG) is championing the IPv6 cause.  IPv6 engineer Erik Kline writes:

Just a year ago, we announced our participation in World IPv6 Day. Since then, the IPv4 address global free pool was officially depleted, each of the five regions around the world receiving one last address block. Soon after, the Asia-Pacific region exhausted its free IPv4 address pool. Hundreds of websites around the world turned on IPv6 for a 24-hour test flight last June. This time, IPv6 will stay on.

For Google, World IPv6 Launch means that virtually all our services, including Search, Gmail, YouTube and many more, will be available to the world over IPv6 permanently. Previously, only participants in the Google over IPv6 program (several hundred thousand users, including almost all Google employees [PDF]) have been using it every day. Now we’re including everyone.

Google is urging its users to go to to test compatibility, as a handful of ISPs are believed to not be ready for IPv6.

While the UFC appears ready to go full-blast with IPv6, adoption plans in the developing world and other regions are much less developed.  It may take several years before the transition is full complete.

One misconception about IPv6 is that it will make you easier to identify or track.  While it will show the world your full address (local+gateway), companies could still opt to use NAT to maintain private single address networks.  And you could still use NAT to obfuscate or otherwise mask your true IPv6 address.  And of course all of the fears overlook the simple fact that whether it's a local or a global IP address, that an IP address cannot identify a person explicitly as there can be multiple users and/or multiple machines.

One true concern is that IPv6 brings some unique firewalling and security risks that users should be aware of, due to its different implementation.

Please define 'more trackable' for us. Do people honestly believe their every keystroke, phonecall, and data entry aren't being recorded and tracked?

Wake up to reality man, large entities (government or private) have the ability to monitor traffic at the global scale. Every receipt, every call, every keystroke, every credit charge, every bank transaction, everything.

Privacy died in the 20th century. People still living in a delusional world will downrate me, unable to come to grips with modern reality.

The larger pool of IP addresses would do away with the need for NAT (at least for the forseaable future). This means that each device connected to the internet will have a genuinely unique IP address, rather than being grouped according to the gateway being accessed.

As for your tinfoil hattery, Its extremely unlikely that every keystroke is being recorded everywhere. Apart from generating an unfeasibly large amount of data, there would be no way of categorising, analysing and disseminating it all. No one can just go "Hey, I wonder what Shig is typing right now" without having previously installed a trojan on your system first.

While it is unlikely that EVERY SINGLE keystroke is recorded, what is known is that once that keystroke leaves your computer, such as happens when I post this comment, then you should regard it as "potentially recorded".
As we have seen with "deleted" emails, which have ended up being used as evidence in court, "potentially recorded" can mean "permanently" (at least while the internet exists).

Why was he downrated? He's actually right...

Obviously every keystroke taking place around the globe isn't being recorded, but depending on your session, even this can be true.

How is this tinfoil hattery? And any data that transmits over a network you administer can be categorized, analyzed, and disseminated at will.

So, what's your point? I just don't get it...?

A typical IPv6 address includes the MAC address of your network adapter. This means that when you connect to a remote network that logs connecting IP addresses (Just about all of them), it is possible to verify and prove that your computer was the exact system that connected to the remote network. Versus the existing system, where it was only possible to trace back to a specific gateway or assigned public IP and anything internally was hidden.

I'm not really current on IP6 as I haven't had to be yet, but I thought you could obtain MAC addresses of devices via IP4 today. WAPs have MAC filters for example. Or cable ISPs keeping track of who's modem is who's.

Either way, you can spoof MAC addresses with IP4 I believe. Would that not be possible still with IP6? I'm sure someone will figure it out if they haven't already.
