Viewing CIDR or Prefix Utilization of a Subnet

• Console
• CLI
• API

• 1. Open the navigation menu and click Networking. Under IP management, click IP Address Insights.
  2. Under Filters, use each option to refine search. You can combine filters to narrow down the search results. Based on the selected filters, the Console displays IP address insights of resources.
  3. Expand the name of the VCN that contains the subnet.
  4. Click the name of the subnet to access the Subnet Details page.
  5. Under Resources, click CIDR/Prefix utilization.
  6. Under CIDR/Prefix utilization, view the list of IPv4 CIDR blocks and IPv6 prefixes the subnet uses along with the percentage of IPs used from the CIDR block or prefix assigned to the subnet.

• Use the network ipam get-subnet-cidr-utilization command and required parameters to view the percentage of IP addresses used from an IPv4 CIDR block or IPv6 prefix assigned to a subnet:

  oci network ipam get-subnet-cidr-utilization --subnet-id subnet_ID_OCID

  For a complete list of parameters and values for CLI commands, see the CLI Command Reference.

• For information about using the API and signing requests, see REST API documentation and Security Credentials. For information about SDKs, see SDKs and the CLI.

  Run the GetSubnetCidrUtilization operation to view the percentage of IP addresses used from an IPv4 CIDR block or IPv6 prefix assigned to a subnet.
