API Gateway support for IPv6 and Reserved Public IPs

You can now use API Gateway to create:

• Public and private IPv4 single stack API gateways, enabled for IPv4 only (default behavior, and supported previously).
• Public and private IPv4/IPv6 dual stack API gateways, enabled for both IPv4 and IPv6.
• Public and private IPv6 single stack API gateways, enabled for IPv6 only.

In addition, when you create a public IPv4 single stack API gateway or a public IPv4/IPv6 dual stack API gateway, you can now specify that the API gateway is to be assigned a reserved public IPv4 address. A reserved public IPv4 address is a separate OCI resource with its own OCID. Having assigned a reserved public IPv4 address to an API gateway, if you subsequently delete the API gateway and replace it with a new API gateway, you can re-use the same reserved public IPv4 address and assign it to the new API gateway. As a result, you do not have to rewrite any existing network configuration, since the API gateway's IP address has not changed.
