Create a Network Perimeter

1. Log in to the Oracle Cloud Infrastructure console and navigate to the relevant Identity Domain.
2. Go to Security tab, under Network Perimeters, click Create Network Perimeter.
3. Enter a name and then enter the exact IP address or IP addresses, IP range, or masked IP address range for the network perimeter. To learn about IP address formats, see Managing Network Perimeters.
4. Click Create.

   After defining a network perimeter, you can assign it to an existing sign-on policy and configure the policy to either allow or deny access for sign-in attempts from IP addresses included in that network perimeter. Alternatively, you can create a new sign-on policy and set the appropriate access control for the network perimeter as needed.
