Learning IPv6?
fsckme asks: "With IPv6 starting to filter its was into the internet I thought that it was about time to learn it. However digging around I've found sites like www.ipv6.org and the IPv6 FAQ but I haven't found a tutorial teaching the basics. Can anyone recommend a nice web based tutorial of even a decent book?"
For the hoplessly bleeding edge, their is a Q uake Version modified to use Ipv6. They even have a server up!
Think nothing is impossible? Try slamming a revolving door.
Try Comer's Internetworking With TCP/IP, Volume 1. It contains a good overview of IPv6.
Hey,
/10 is a leagacy compliance feature.
IPv6 has a very diffrent way of nameing things. First off you have the folling addresses on each card;
v6 (128bit in hex)
Multicast (128bit in hex w/reserved header)
Group Multicast (128bit in hes w/reserved header)
Network Multicast (128bit in hes w/reserved header)
Network (same as above)
Broadcast (same as above)
and last but not least all those v4 addresses too. so yes the

There was an article in Sysadmin magazine recently.

Assembly is the reverse of disassembly.
Implementing IPV6: Supporting the Next Generation Internet Protocols
A former colleage of mine had this book and liked it. I have not read it personally but I just checked it out on Amazon. It looks like it has a lot of useful information.
Here's a bit from their description:
"IPv6 is a critical new technology, essential for the geometrically increasing traffic on the net. The second edition of Implementing IPv6 shows networking professionals the how and why of making the transition -- and points out both IPv6's capabilities, and the potential issues it raises for network managers."
Inside you'll find everything you need to:
Learn the IPv6 addressing architecture.
Keep up to date with the latest Request For Comments (RFC) documents.
Understand such hot issues as upper layer protocols, APIs, and security.
Manage IPv6 Internetworks.
Master transition mechanisms and routing.
Troubleshoot autoconfiguration and local network issues.
Understand all the capabilities and shortcomings of the next generation...

And they are part of the FreeBSD ports tree already.
There are technical documents here from Cisco. That doesn't make them easy to read, but it should be at least correct. Happy reading!
Better yet, subscribe.
WinXP can do dual-stack (IPv6 and IPv4) just fine. Just run 'ipv6 install' from a command prompt and you'll have a working autoconfiguring IPv6 host. Their docs are quite helpful.
I don't know anything about IPv6 on Macs, though I'd love to try it. Apparently OS X can do it, though all the pages I've found to describe it are in Japanese.
noah
Programming IPv6 apps is actually quite easy, and actually involves programming protocol family independent code if you want to do it right. On the client end, this basically involves using a function (getaddrinfo(3)) to get a linked list of all addresses associated with a given hostname in any protocol family (IPv4, v6, or even something fun like AppleTalk) and walking along the list until you get a good connection. This has the added advantage that if you are trying to connect to a host that has multiple IP addresses, and some of them are non-responsive (i.e. a round-robin DNS situation), your client will try connecting to each IP address until it succeeds.
If you're trying to learn how to configure and use IPv6 on your hosts, try some of these:
I've been messing around with IPv6 for a couple years, and reading about it for a couple more, which still puts me behind the curve a bit. Bottom line is this is really new stuff, and the kind of basic information out there is just that, basic, in the same way assembler is basic (though not as basic as straight machine code). There is very little in the way of easy to follow directions, let alone complete network stacks and applications to make use of them. If you want a (mostly) complete IPv6 stack, go with BSD.
6 _tutorial.html. The specifics are BSD oriented, but the concepts apply everywhere.
The best web resource i've found for linux specific information is a HOWTO by Peter Bieringer. It's located at http://www.bieringer.de/linux/IPv6/index.html
http://www.hs247.com/ Has a bunch of links to a ton of information, and is OS agnostic.
One book I've found to be pretty helpful is called IPng and the TCP/IP protocols: Implementing the Next Generation Internet. The first half of the book rambles a bit, but the second half gets down to business quite nicely. It can be a bit technical at points, which I like, but may be a dry for some.
O'Reilly has a good article on 6to4 tunneling at http://www.onlamp.com/pub/a/onlamp/2001/06/01/ipv
If you want to start writing some code that uses IPv6, the ever popular UNIX Network Programming is a great resource.
fe80 is a link-local address (i.e. your ethernet card). Your Ethernet card's MAC address is stored in the lower 64 bits of the address (54:ff:fe:6e:f6:c2). There's a lot of useful info at http://www.netbsd.org/Documentation/network/ipv6/.
