Dept. of Defense IPv6 Interoperabilty Test Begins
securitas writes "The Department of Defense has launched Phase I of its delayed IPv6 interoperability test (mirror) in a six-month project dubbed Moonv6. It is the largest North American IPv6 test ever and its goal is to evaluate IPv6 for 'network-centric military operations.'
Phase II was originally scheduled to begin in January 2004 but may be delayed due to the late start of the current test.
'IPv4 addresses are 32 bits long, enough for around 4 billion unique addresses.' In contrast, the IPv6 address length is '128 bits, or 340 billion billion billion billion unique addresses.'
Experts hope this will solve a predicted IP address shortage as more devices are created to use the Internet."
Whatever happened to IPv5? What was special about it?

I thought NAT worked well. That is larger than a mol. Think of it like this some where there are 4billion Universes, and in each of these 4 billion universes, there are 4 billion galexies and in these 4 billion galexies there are 4 billion planets just like our with approximately 4 billion people.
Maybe I am short sighted, but is this really needed? Even if we have nano devices with multiple addresses this is more than will be used. 64 bit would have been over kill. And besides like I said NAT works fine.

well, you get the idea...All's true that is mistrusted
Here is a web site and project that tracks how IPv4 addresses are allocated and misused, i.e. hijacked: http://www.completewhois.com/statistics/index.htm
The way I read it, a huge percentage of IPv4 addresses are not even being used...
With built in things like IPSec + Auto Config it will help the DOD deploy things quickly and securly. Of course for the rest of us it might take another 5-10 years before all running on IPv6

I would like people to call my phone with VoIP. That is a "service", and I need an IP address for it.
Finally! A year of moderation! Ready for 2019?
Does anybody know why TPTB decided on 128 bits for IPv6? 64 would have been more than enough. IP addressing is not like memory or disk space, where you can envisage ever-increasing requirements. It's an addressing scheme for devices. 64-bit addresses are big enough to have nearly a billion uniquely addressable devices for every human being on Earth. Why isn't that enough, even allowing for some spare bits to make address-assignment easier? Do you plan to ask for a billion addresses for the billion devices you plan to attach to the Internet?
1. Eliminating the header checksum makes it substantially easier to develop forwarding ASIC.
2. It was generally believed that the IPv6 header checksum doesn't provide all that much value. Suppose, for a moment, that the IP header became corrupted in some way. What's the worst thing that could happen? Eliminating the header checksum removes intelligence from the core and relocates it to end nodes [In this case, Intermediate systems no longer need to perform error detection. Instead, developers who require reliability can make use of existing fucntions build into the transport layer]
