Whitelisting IP Addresses for Snowflake-Looker Connection

Hi All,

I need some guidance on which IP addresses should be whitelisted in Snowflake to enable our connection with Looker. After searching through various forums, I’ve come across conflicting advice and could use some clarification.

One source suggests whitelisting the address 142.251.74.0/23, while another recommends allowlisting IP ranges for us-central1, us-east1, or us-west1 from this list: Google Cloud IP Ranges.

Which approach is correct? Additionally, our support team is concerned about the number of IP addresses that might need to be opened. Any help or insights would be greatly appreciated.

Thank you for your assistance!
