address is called the Media Access Control (MAC) address. A MAC address is
a combination of manufacturer- and factory-assigned numbers. This method
ensures that the device has a unique address.
The second address is a combination of numbers that identifies a system at the
TCP/IP protocol suite. This method identifies individual stations that are
connected to subnetworks of an internetwork. The internetwork is a group of
smaller networks, such as subnetworks or subnets, which are connected by
routers. The routers know the addresses of the devices on their LAN. The
router can pass messages on the local subnets directly to the recipients or pass
the message out of the LAN if the message is intended for a destination
beyond the local subnet. Routing protocols provide the mechanism of finding
the efficient path for data to pass between the source and destination. Refer to
Figure B-3 for examples of routing an address.

IP network numbers represent portions of obtained addresses that companies
and groups utilize for Internet access to their locations. When a company
acquires an IP address, a range of numbers using that address can be assigned
to devices on their network. The range of IP addresses available to a company
depends on the type of address that it has acquired. A breakdown of the types
of addresses and the numbering schemes is depicted in Figure B-4 and
Table B-1.
