+  The <application>ip</application> utility can be used to assign <systemitem class="protocol">IP</systemitem> addresses to an interface. The command takes the following form:
+<synopsis>ip addr <optional> add | del </optional> <replaceable>address</replaceable> dev <replaceable>ifname</replaceable></synopsis></para>

+To assign an <systemitem class="protocol">IP</systemitem> address to an interface, issue a command as <systemitem class="username">root</systemitem> as follows: 
+<screen>~]# <command>ip address add 10.0.0.3/24 dev eth0</command>
+The address assignment of a specific device can be viewed as follows:
+~]# <command>ip addr show dev eth0</command>
+2: eth0: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc pfifo_fast state UP qlen 1000

+      <para>
+        As the <application>ip</application> utility supports assigning multiple addresses to the same interface it is no longer necessary to use the alias interface method of binding multiple addresses to the same interface. The <application>ip</application> command to assign an address can be repeated multiple times in order to assign multiple address. For example:
+        <screen>~]# <command>ip address add 192.168.2.223/24 dev eth1</command>
+~]# <command>ip address add 192.168.4.223/24 dev eth1</command>
+~]# <command>ip addr</command>
+3: eth1: &lt;BROADCAST,MULTICAST,UP,LOWER_UP&gt; mtu 1500 qdisc pfifo_fast state UP qlen 1000
+    link/ether 52:54:00:fb:77:9e brd ff:ff:ff:ff:ff:ff
+    inet 192.168.<emphasis role="bold">2</emphasis>.223/24 scope global eth1
+    inet 192.168.<emphasis role="bold">4</emphasis>.223/24 scope global eth1</screen>
+    </para>
+        <para>The commands for the <application>ip</application> utility are documented in the <filename>ip(8)</filename> manual page. Note that <application>ip</application> commands given on the command line will not persist after a system restart.
