Changing the main IP after adding an IP

After a day of adding an IP through "Home / IP Functions / Add a New IP Address"
My main IP was changed to the new IP I added and I had a license problem.
I may add more IPs. How can I avoid this problem?

  • Have you rebooted the server after you added the new IP?
  • If you check "Show or Delete Current IP Addresses" in WHM the new IP you added is the one without "Delete" option?
  • By any chance have you used the "IP Migration Wizard" as well?

  No i have not reboot the server.

  i  Can't login to WHM now.

  i did not use "IP Migration Wizard".

   

  I tried to change the main IP by changing it in some files. I edit /var/cpanel/mainip , /etc/ips, /etc/hosts

  and restart the network. Now I don't even have PING.

  I used rescue mode to revert the change but I still don't have ping.

  It was a bad idea to manually edit files :( I believe the best would be to hire a professional who can have a closer look at your server and see what is going on. You can find cPanel certified Professionals here.

  Verify that your network service is operational and confirm that the IP address is displayed in the Ethernet services by utilizing the 'ifconfig' command.
  
  sudo systemctl status network

  You basically can't do what you did.  When you add an IP through WHN it's adding it on as an additional IP to that NIC.  You would still need the "main" IP to be there and function.

  If you are trying to change the main IP of the server you'd need to:

  • Change the IP as the OS level (how you do that depends on your OS)
  • Change the IP that the cPanel license is tied to
  • Reboot the server (so the new IP takes effect)
  • Log in to WHM and go through the IP Migration Wizard (which will change all references of the old IP to the  new IP)
