Changing license IP
You can change the IP address on the license edit form. Click 
menu → Edit. The value of the IP-address field is the address that is currently valid for the selected license.
You can change the IP address for your license only once a month.
If you need to change the IP more often, please contact the ISPsystem technical support team.
You can leave the IP address field blank and activate the license with an activation key.
You must activate the license before you install the panel on the server.
