--
-- Provides a complete mapping from the public accelerator IP address and
-- port to destination EC2 instance IP addresses and ports in the virtual
-- public cloud (VPC) subnet endpoint for a custom routing accelerator. For
-- each subnet endpoint that you add, Global Accelerator creates a new
-- static port mapping for the accelerator. The port mappings don\'t change
-- after Global Accelerator generates them, so you can retrieve and cache
-- the full mapping on your servers.
--
-- If you remove a subnet from your accelerator, Global Accelerator removes
-- (reclaims) the port mappings. If you add a subnet to your accelerator,
-- Global Accelerator creates new port mappings (the existing ones don\'t
-- change). If you add or remove EC2 instances in your subnet, the port
-- mappings don\'t change, because the mappings are created when you add
-- the subnet to Global Accelerator.
--
-- The mappings also include a flag for each destination denoting which
-- destination IP addresses and ports are allowed or denied traffic.
--
-- This operation returns paginated results.
