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
