IP address ranges and DNS names
This table gives you IP address ranges and DNS names for the UAT and production environments in the AMER (AWS), AMER (OCI), and EMEA regions. You can use this information to allowlist the IP address or DNS name for your environment.
tip
We recommend allowlisting DNS names because the IP addresses of 3rd-party services may change at any time.
