Response Structure

  • (dict) –

    • ByoipCidrs (list) –

      Information about your address ranges.

      • (dict) –

        Information about an address range that is provisioned for use with your Amazon Web Services resources through bring your own IP addresses (BYOIP).

        • Cidr (string) –

          The address range, in CIDR notation.

        • Description (string) –

          The description of the address range.

        • AsnAssociations (list) –

          The BYOIP CIDR associations with ASNs.

          • (dict) –

            An Autonomous System Number (ASN) and BYOIP CIDR association.

            • Asn (string) –

              The association’s ASN.

            • Cidr (string) –

              The association’s CIDR.

            • StatusMessage (string) –

              The association’s status message.

            • State (string) –

              The association’s state.

        • StatusMessage (string) –

          Upon success, contains the ID of the address pool. Otherwise, contains an error message.

        • State (string) –

          The state of the address pool.

        • NetworkBorderGroup (string) –

          If you have Local Zones enabled, you can choose a network border group for Local Zones when you provision and advertise a BYOIPv4 CIDR. Choose the network border group carefully as the EIP and the Amazon Web Services resource it is associated with must reside in the same network border group.

          You can provision BYOIP address ranges to and advertise them in the following Local Zone network border groups:

          • us-east-1-dfw-2

          • us-west-2-lax-1

          • us-west-2-phx-2


          You cannot provision or advertise BYOIPv6 address ranges in Local Zones at this time.

    • NextToken (string) –

      The token to use to retrieve the next page of results. This value is null when there are no more results to return.
