Re: IPv6 in Education Question
You're either going to have to sell them on future-proofing or We're sailing off the edge of the world in two years, there be dragons there, train your folks now. Remember that there are two IPv6 transitions - introducing IPv6 and forcing some people onto it - getting rid of IPv4 after IPv6 support is universal. Death of NAT NAT's not going away for a long time - IPv6 doesn't need it for address space conservation, and pretends not to need it very much for renumbering IPv6 to IPv6, but it's widely used as a firewall substitute and administrative convenience. The first IPv6 transition will eliminate some NAT in pure-v6 environments, so there will be applications that are no longer broken and can Just Work, but it'll also introduce several different flavors of IPv4-to-IPv6 NATs/tunnels/etc., so there are other applications that will get broken in new and creative ways. The second IPv6 transition may really finish eliminating NAT, but that won't be for *years*, and you'll need to get all your users deeply involved in IPv6 long before that. Other than networking research and networking-related training, there really aren't education-specific applications of IPv6; there are just sites that you can or can't reach with IPv4 or IPv6. Any big commercial sites will stay reachable with IPv4 for a long time, certainly until IPv6 has been well established for a couple of years, and while there may be new content that's IPv6 only after a while, commercial content sites are more likely to buy IPv4 space if they need it. And most educational sites big enough to be Really Cool already have enough IPv4 space to last a few years, though they may very well start adding IPv6 connectivity just like commercial sites will. -- Thanks; Bill Note that this isn't my regular email account - It's still experimental so far.

Or sell them on the point that IPv6 is where the innovation is. We have literally no idea what our children will be doing with restored end-to-end transparency and abundant addresses. That's where education has to be. It's not an educational feature, but a very important emergent property... Remember that there are two IPv6 transitions - introducing IPv6 and forcing some people onto it - getting rid of IPv4 after IPv6 support is universal. And the third (well, probably the second, between those two) - learning to *really use* IPv6. Death of NAT NAT's not going away for a long time - IPv6 doesn't need it for address space conservation, and pretends not to need it very much for renumbering IPv6 to IPv6, but it's widely used as a firewall substitute and administrative convenience. Both oddities that I confidently predict will not survive long in the face of the enormous advantages that properly-implemented IPv6 can bring. A teensy packet filter substitutes for the security aspect, and PI address space deals with the second. The first IPv6 transition will eliminate some NAT in pure-v6 environments, so there will be applications that are no longer broken and can Just Work, but it'll also introduce several different flavors of IPv4-to-IPv6 NATs/tunnels/etc., Sure, there will be practical reasons why people need this or that half-solution, this or that broken stopgap. But we can keep the Dark Years fewer by trying not to use them. Any big commercial sites will stay reachable with IPv4 for a long time, certainly until IPv6 has been well established for a couple of years, We've all been here before. The same thing will happen globally as happened in thousands of networks with IPX, Appletalk and DECNet. IPv4 remains only on sufferance. The alternative rapidly becomes vastly more attractive as the connectedness of the new protocol snowballs. Pressure builds from inside and out, and - way sooner than anyone expected - there is a sort of communal sigh of relief and the old stuff gets quietly dropped. I wonder what landmarks we should designate as IPv4 is done - Google dropping support for IPv4? And I wonder what the landmarks for the beginning of the end would be - Windows 15 coming out with IPv4 disabled by default?

Re: IPv6 in Education Question
It is such a great opportunity. I had chance to give similar speeches in Brazil last year, and choosed to stress the following topics, besides the basic catechism: - IPv6 is inevitable, it is already part of Internet, and will be fully deployed in few years. Its deploying is slow, but the momentum is increasing; - Universities had an important role in IPv6 development some years ago, and should be leading this process now, but they are not; - It is very important to the Internet, that the network engineers learn about IPv6, and use IPv6, inside universities and schools... - Universities could help the national industry to adopt IPv6 in their products, to secure the current market, or to conquer new ones.

Re: IPv6 in Education Question
Todd, Cisco is offering a 4 part series of Webcasts about IPv6 for Education. I've watched the first two, and they haven't really been too vendor specific, but some of it has been insightful, especially from an Education standpoint. The first two are up on the web, and the last two are coming, March 30th and April 13th. These last two are on Security and Unified Communications, which may not be as vital to your talk. If you (or anyone else) would like a link to the registration for all of these, hit me off list, as I wasn't sure if it would be considered spamming or not.

I have the usual catechism of reasons/advantages from the network side but was wondering if there were any good education specific applications of v6. If implemented properly (i.e., not by using IPv6 to fake all the properties of IPv4, as so many people seem bound and determined to do), then there are several characteristics of IPv6 networks that are of educational interest, though nothing in the protocol is education-specific. First and foremost is that IPv6 is simpler and thus cheaper. Easier to build networks, merge them, expand them, contract them, split them. Every subnet is the right size - no more slicing and dicing subnets, endlessly rearranging too few addresses in new configurations. Design costs go down, admin costs go down, management costs go down, equipment costs go down. Because IPv6 is simpler, security is by definition better and cheaper. Education being perennially penurious, all this has got to be interesting! IPv6 is easier to teach than IPv4. It doesn't have as many edge cases and entrenched workarounds, the notation is cleaner, the protocols are cleaner, and the same set of protocol tools (multicast, ICMPv6, ND etc) is used more consistently. End-to-end transparency means that IPv6 supports peer to peer naturally. That means everyone (students, teachers, parents etc) can talk to each other more easily without having to involve third parties, and can talk to each other from anywhere on the globe. Less mediation, more direct, more distributed. The death of NAT will mean that more and more stuff will be hosted locally - on teaching machines, student laptops, home PCs, mobile phones. I think we will see fragmentation and distribution of things that are now monolithic. Things like Facebook, Twitter, MySpace and so on will be reduced to special purpose indexing services - or will die. Why use them when you can have all your stuff on your mobile phone, accessible 24/7, wherever you are? I'm not sure about the future of VPNs. Mobile IPv6 is effectively a global, standardised, very low-cost, built-in VPN. Students can be inside the school network from home, on the road, overseas without special infrastructure outside the home network. So I'd expect to see IPv6 change the face of educational IT - but it will change the face of IT everywhere.
