In this post, i will share the simple command to display the CentOS and Redhat Enterprise linux(RHEL) ip address. This command has been tested on Linux CentOS 5.8 server and may working on other CentOS and RHEL version as well. There are two alternative command to display ip address :
1. Display ip address using “ip address show” command :
[root@centos58 ~]# ip address show
1: lo: mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
2: eth0: mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:0c:29:a1:17:ad brd ff:ff:ff:ff:ff:ff
inet 192.168.1.53/24 brd 192.168.1.255 scope global eth0
2. Display the ip address using “ifconfig” command :
[root@centos58 ~]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:A1:17:AD
inet addr:192.168.1.53 Bcast:192.168.1.255 Mask:255.255.255.0
