Re: How big is the Internet? - about the size of a strawberry

[Jayram Deshpande <jaydesh9 () gmail com>]

If we try to comprehend the Internet in terms of number of boxes that can reach from their local networks to globally 
routable destinations, we have to take into account Multi- NATed , multi-tunneled (ipv6 over ipv4 in a VPLS , and other 
crazy scenarios such v6 over v4 in a VPLS running over VXLANs : is that even realistic ? ) overlay networking 
environments. So also the overlays formed to talk to sensors who can understand say TM/TC ( Telemetry/Tele-commands). 

In terms of the  Address space , the problem statement shows more convergence.
