+Change default for `default_ingress_ip_address_type` from `dualstack` to `ipv4`. When `dualstack` is configured, the
+Ingress will fail if the VPC does not have an IPv6 CIDR block, which is still a common case. When `ipv4` is configured,
+the Ingress will work with only an IPv4 CIDR block, and simply will not use IPv6 if it exists. This makes `ipv4` the
+more conservative default.
