Why transition to IPv6? - or why IP?

Internet technologies are getting deployed everywhere
Always-on connectivity is changing the world

Every equipment has to be always-on, IP connected
Fridge, microwave, taxicabs, cellphones, gaming machines
Reduced cost of network operation, easier deployment of new apps, tighter integration with IP services (like email/web), wide variety of new applications/chances

Use of IP = layer 2 independent
Can use cellular, 802.11, GbE, whatever available
Can switch to latest/cheapest technology as they become available
