If we try to comprehend the Internet in terms of number of boxes that can re=
ach from their local networks to globally routable destinations, we have to t=
ake into account Multi- NATed , multi-tunneled (ipv6 over ipv4 in a VPLS , a=
nd other crazy scenarios such v6 over v4 in a VPLS running over VXLANs : is t=
hat even realistic ? ) overlay networking environments. So also the overlays=
formed to talk to sensors who can understand say TM/TC ( Telemetry/Tele-com=
mands).=20
In terms of the Address space , the problem statement shows more convergenc=
e.=20
