Prerequisites

Whitelist CData IPs

To establish a connection to Snowflake, you need to allow access to Snowflake via CData’s IP. When hosting Snowflake behind a firewall, you must safelist these IP addresses in your firewall.

  • Range: 52.224.0.160 to 52.224.0.175

  • CIDR notation: 52.224.0.160/28

Ensure Snowflake is Publicly Accessible

Provide a public facing IP/domain to connect to this data source. The following private IP ranges do not work:

  • 10.0.0.0 to 10.255.255.255

  • 172.16.0.0 to 172.31.255.255

  • 192.168.0.0 to 192.168.255.255

  • 127.0.0.1 (aka ‘localhost’)
