Some IP addresses are reserved for special uses and cannot be used for host, subnet, or network addresses. RFC 1166, “Internet Numbers,” contains the official description of IP addresses. 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. To receive an assigned network number, contact your Internet service provider. To assign IP addresses to network interfaces, perform this procedure: Procedure Configuring IP Unicast Routing Assigning IP Addresses to Network Interfaces Command or Action Purpose Step 1 enable Example: Device>enable Enables privileged EXEC mode. Enter your password if prompted. Step 2 configure terminal Example: Device#configure terminal Enters global configuration mode. Step 3 interface interface-id Example:
Enters interface configuration mode, and specifies the Layer 3 interface to configure. Configuring IP Unicast Routing 11
