DLH.io connects to your source systems over the internet or VPC (AWS PrivateLink, GCP Private Service, Azure Private Link) where possible. For most systems such as cloud based applications whitelisting the IP address is not required. However for databases and other secure cloud architecture in order for DLH.io to securely connect to your data systems and sources this may be required.

DLH.io uses several Internet Protocol (IP) address to effectively connect to your data sources and move your data to Snowflake. When your source is gated, on a public cloud, on-premise, behind a firewall, etc. then you need to whitelist our IP addresses in order for the connection to be successfully. Use the following IP addresses below and grantlist/whitelist (aka SafeList) all of them on your network security and/or firewall.

If you will be deploying any Analytics packages, including Snowflake Usage Analytics you'll need to grantlist/whitelist dbt Cloud's IP addresses.
