save and exit

[root@reyaz ~]# systemctl restart network

At first check your ether name by using the Linux command "ifconfig"

Then open the file where all info is stored for your network (ether)
 [root@reyaz ~]# vi /etc/sysconfig/network-scripts/p8p1

Then edit "NAME" line and "IPADDR" line according to my steps and image

After that save and exit. 

Now restart your system Network.

Check again by command   "ifconfig"

Done.
