How to assign an IP address in Ubuntu using command line

Computers may be assiged a static IP address or assigned one dynamically. Typically servers and institutions will use a static IP which will not change each time u get connected. Workstation will use Dynamic Host Configuration Protocol (DHCP) for IP address assignment. It is more easily to find a system if the IP address does not change and is static.


Use the Command Line:

    /sbin/ifconfig eth0 192.168.10.12 netmask 255.255.255.0 broadcast 192.168.10.255                  

 
The ifconfig command does NOT store this information permanently. Upon reboot this information is lost. Manually add the network configuration to /etc/network/interfaces  as shown in my next post .
