ipAddressType

A resource gateway can have IPv4, IPv6 or dualstack addresses. The IP address type of a resource gateway must be compatible with the subnets of the resource gateway and the IP address type of the resource, as described here:

• IPv4Assign IPv4 addresses to your resource gateway network interfaces. This option is supported only if all selected subnets have IPv4 address ranges, and the resource also has an IPv4 address.

• IPv6Assign IPv6 addresses to your resource gateway network interfaces. This option is supported only if all selected subnets are IPv6 only subnets, and the resource also has an IPv6 address.

• DualstackAssign both IPv4 and IPv6 addresses to your resource gateway network interfaces. This option is supported only if all selected subnets have both IPv4 and IPv6 address ranges, and the resource either has an IPv4 or IPv6 address.

The IP address type of the resource gateway is independent of the IP address type of the client or the VPC endpoint through which the resource is accessed.
