Error while adding an Addon domain in cPanel. (sorry the domain is already pointed to an IP address)

By using the “WHM/cPanel” you can basically handle your accounts in a server. You can make sub-domains, Addon domains, parked domains from the control panel. Here I am describing a fix for the error below while adding an Addon domain.
[wpfmb type=’error’ theme=2]The domain is already pointed to an IP address that does not appear to use DNS servers associated with this server.[/wpfmb]
For solving this problem you can use any of the choices below
Option 1: Modify your name servers according to your host’s name servers. It may cause downtime, however, and isn’t really suggested.
Option 2: You can simply solve this problem from your WHM. 
WHM > Tweak Settings > Domains > Allow Remote Domains make sure that this option is checked:

Now you can add new Addon domains those having name servers other than your server.
