[AusNOG] DS-Lite is IPv6-only from outside...

[Scott O'Brien]

There's an awesome NANOG video about the Xbox One and use of IPv6 and where it's preferred (a hint, even if native v6 is available at both ends, it's not always/often the preferred p2p method.)  https://www.youtube.com/watch?v=VSjljW4clPM

It is fascinating to see how IPv6 is being used in more and more places though (with the use of tunnelling protocols for the most part.)  It might be worth pointing out that while Microsoft is going down the Teredo route (pun intended), Apple is often overlooked as having been pushing IPv6 now for several years since OSX 10.5 with their Back to my mac feature for p2p connectivity (more tunnelling with DNS tricks and ULA's, see http://tools.ietf.org/html/rfc6281 )  Hopefully with v6 being in more places we'll just see native p2p connections without the need for all this tunnelling and added complexity much down the track.

I'd never heard of DS-Lite before though this post though.  Pretty cool stuff!  Shame the term DS-Lite has become that much harder to google after Nintendo did a fantastic job with their marketing ;P
