Addresses

Addresses are associated with both software and hardware. The address is the means by which the sending or control station selects the station to which it sends data.

Addresses identify receiving or storage locations. A physical address is a unique code assigned to each device or workstation connected to a network.

For example, on a token-ring network, the netstat -iv command displays the token-ring card address. This is the physical network address. The netstat -iv command also displays class-level and user-level address information. Addresses are often defined by software but can be created by the user as well.
