So Im giving an introductory talk on IPv6 for a state wide conference for tech coordinators for education. 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.
