I tell folks that if ipv4 run-out is the problem in eyeball networks, then DS cannot be the solution since it has the same problematic reliance on a scarce ipv4 resource. I spent a lot of time focusing on ipv6-only networking for mobile and in many cases, thanks to world v6 launch and ipv6-only based access network transition schemes (ds-lite, MAP, 464xlat) they can provide a solution for eyeball networks that is one step away from ipv6-only. .... Instead of DS, which is just one step beyond ipv4-only with a foggy road to getting off scarce / expensive / broken ipv4 Content networks are a different beast that must be dual-stack to reach all the eyeballs CB > The problem with picking a 10-year or 5-year "campaign" is that > underestimating the amount of time makes us look like "the sky is > falling" and too long gives people a reason to procrastinate. > > Then again...
