Re: He should keep quiet and be thought a fool rather than open his mouth and prove it
At first glance I thought his comment about cdns didn't make sense, but with a little more thought it made much more sense. What hie is saying is that in theory each cdn provider only needs a handful of public addresses. All of these cdn addresses would then be anycasted that the primary dge network. As more and more sites and services move onto said cdn providers more and more of the internet becomes hidden inside the cdn network, hence freeing lots of up space. Remember the routing on a cdn is don't at layer 7 mostly not layer 3
