Does this make any sense? My understanding of IP addressing and routing is 
that a
device's IP address is a function of the network it is plugged into. My laptop
routinely acquires (via DHCP) different IP addresses during the day as I 
moveamong
my home and several offices.
Every ethernet-ready device manufactured already has a unique ethernet 
address.
What is SONY up to?
