'How to connect Google Data Studio to GCP Postgres DB

In the instructions to connect Google Data Studio to a PostGres DB it says you must whitelist these 3 IP's

142.251.74.0/23

2001:4860:4807::/48

74.125.0.0/16

The problem is the second one. GCP will not allow a IPV6 address in it's allowed connections.
