-When you create an API, you specify the type of IP addresses that can invoke your domain. You can choose IPv4 to allow IPv4 addresses to invoke your domain, or you can choose dualstack to allow both IPv4 and IPv6 addresses to invoke your domain. We recommend that you set the IP address type to dualstack to alleviate IP space exhaustion or for your security posture. For more information about the benefits of a dualstack IP address type, see [IPv6 on AWS](https://docs.aws.amazon.com/whitepapers/latest/ipv6-on-aws/internet-protocol-version-6.html).
