[Jesse_S]

I have a dedicated centOS server and I need to add IP permanently on it.
So, how to add IP Permanently on dedicated server?
Can I utilize system-config-network?

You can find out the network files in :

/etc/sysconfig/network-scripts/ifcfg-eth0 , /etc/sysconfig/network-scripts/ifcfg-eth0:1 ifcfg-eth0:2 etc

Once you able to find out the network files, just up to them with:

# ifup eth0:1

Create a new file for each virtual interface or add a range to 1.

Thank you Kelvin.
I don't know how to add a range. Can you please explain?

[KelvinSmith]

Follow the steps given below to add a range:

File: /etc/sysconfig/network-scripts/ifcfg-eth0-range

IPADDR_START= 000.000.000.000
IPADDR_END= 000.000.000.000
CLONENUM_START=0

# ifup ifcfg-eth0-range

(Replace 000.000.000.000 with your IP's as required)
