Neural networks are "connectionist," and do not use anything like 
"routing tabels" or "packet switches," so concepts like "IP addresses" 
or "packet headers" are totally irrelevant to them. The connections
between the limbs and the areas of the brain that control them are
"fixed point-to-point links" and essentially hardwired past the age 
of about 3 years, so that when the specific groups of neurons that 
connects to the nerve fibers that run from the area of your brain
controlling your leg to your leg fires, your leg muscles twitch --- 
which is one reason why recovery of limb function after a stroke 
or other forms of brain damage to a motor control area is so difficult.
