This is akin to the DNIC (X.121)addressing scheme used in X.25
networks. The first few octets of the address specified the continent,
backbone network on that continent, and geographic region (area code).
This sure made routing very easy as the address contained intelligance
rather than just a mish-mash of numbers. Routing is accomplished by the
first few octets *only* untill the packet arrived within its destination
area code, then full address routing would take place.
