To turn off auto-renewal of your IP subnet start with opening your terminal window and navigating to IP Address Market>Monetizing IPs>Manage
Select and click the subnet of which you want to turn off auto-renewal.
Press Subnet Setup (No. 1 in the picture) here you can see all information about your subnet. Click edit to change the settings of the subnet (No. 2 in the picture).
Press on the slider to turn off the auto-renewal (Should change from green color to grey) and then press Save changes.
Congratulations, you have successfully turned off auto-renewal for your subnet.
If auto-renewal is disabled, the feature cannot be re-activated during the two month grace period before the subnet's expiration date, after which the delisting process activates.
