How do I set a default VirtualHost for each IP address in cPanel / WHM

1. Navigate to WHM / Service Configuration / Apache Configuration / Include Editor.

2. Under "Pre VirtualHost Include", select the "2.4.X" Apache version or "All Version".

3. Add the VirtualHost for the IP address over the webserver ports in the box that opens.

4. Click "Update".

5. Click "Restart Apache".
