A very interesting point. In order to save precious CGN resources,
it would not be surprising to see some ISPs asking CDNs to provide
a private/non-routed behind-CGN leg for local CDN nodes.
For this to work, the CGN users would probably have a different
set of DNS servers (arguably also with a private/non-routed
leg) or some other way to differentiate these CGN clients. Lots
of fun in the future debugging that.
