<p>
App Runner provides you with the option to choose between <i>Internet Protocol version 4 (IPv4)</i> and <i>dual
stack</i> (IPv4 and IPv6) for your incoming public network configuration. This is an optional parameter. If you
do not specify an <code>IpAddressType</code>, it defaults to select IPv4.
</p>
<note>
<p>
Currently, App Runner supports dual stack for only Public endpoint. Only IPv4 is supported for Private endpoint.
If you update a service that's using dual-stack Public endpoint to a Private endpoint, your App Runner service
will default to support only IPv4 for Private endpoint and fail to receive traffic originating from IPv6
endpoint.
