[arin-ppml] Straw Poll

Generally right.

Fred, SmartGrid will have different security requirement levels depending on what is communicating.  SCADA and grid controls will not likely be in the same network with home broadcast control and pricing info (I sure wouldn't!  and v6 makes that simple separation even easier) nor will they use the same authentication. Industrial controls probably lie in between.

Just as FYI, there are appropriately 350 million meters in the US from some stats I saw earlier this week and that doesn't include any Grid infrastructure; just end user metering (certainly not frigs :-).  Anything that we can do to encourage good designs (i.e. IPv6) seems appropriate.  

FINALLY, we need to remember that existing "critical infrastructure" from Power to ICUs to water are likely to need some bridging IPv4 allocations to their "EXISTING" control networks before they can move them to IPv6.  At this point I'd be far more concerned about reserving some resources for bridging existing CI control networks than most anything else; those bridging resources are something we definitely should plan for.

Take care
Terry
