Hi ankitmathur,

ifconfig eth0 address x.y.z.w
replace eth0 by your network device (which most likely will be eth0 anyway) and x.y.z.w with the required IP address

If you want permanent changes (across reboot), login as root and run netconfig and fill in the values in the dialog

U can run "netconfig" command for that...

Also "neat" also may help you..

which is written at /etc/sysconfig/network-scripts/ifcfg-eth0

also do

service network restart
 or
/etc/init.d/network restart

[root@francoisvn ~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0

example of my eth0 after the change.

DEVICE=eth0
BOOTPROTO=none
BROADCAST=192.168.1.255
IPADDR=192.168.1.245
.......
......
etc....

changed my IPaddr from .18 to .245 and wrote and quit the file and then ran
