Assigning IP Addresses to Network Interfaces
An IP address identifies a location to which IP packets can be sent. An interface can have one primary IP address. A mask
identifies the bits that denote the network number in an IP address. When you use the mask to subnet a network, the
mask is referred to as a subnet mask.
