Update, on Centos 7 and onwards this works and is a great mini view of interface IPs, especially if you have a lot of interfaces.
    ip -br -c a
\\ 
\\ 
ip is the ip command
-br is brief
-c is colourised
a is all interfaces
\\ 
\\ 
There are several ways to look for an IP Address, and indeed to display the addresses, here are a few exaples.
\\ 
\\ 
From the command line:
\\ 
        ifconfig
\\ 
This will display all IP Addresses configured on al Interfaces, on a server this can be a long list that scrolls off the page, to stop the results scrolling of the page use:

        ifconfig |more
\\
If you know the interface name, you can use that to show the IP details of just that interface:
\\ 
        ifconfig eth0
\\ 
This will give the details for a single interface only
\\ 
\\ 
If an interface is using DHCP, and you see no IP Address, then you might have a link issue, to check this you can use:
\\ 
        ip link show
        ip link show eth0
\\ 
\\
We can use grep to filter out just the information we require:
\\ 
        Show MAC address of an interface - ifconfig eth0 |grep HWaddr
\\
