EC2 / Client / withdraw_byoip_cidr



Stops advertising an address range that is provisioned as an address pool.

You can perform this operation at most once every 10 seconds, even if you specify different address ranges each time.

It can take a few minutes before traffic to the specified addresses stops routing to Amazon Web Services because of BGP propagation delays.

Response Structure

  • (dict) –

    • ByoipCidr (dict) –

      Information about the address pool.

      • 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.
