Opensense IP addresses for whitelisting

Overview

Not required for standard implementations

IP whitelisting (allowlisting) isn’t required for standard implementations.

If whitelisting is required, whitelist the IP addresses below, so that communication isn’t interrupted by firewalls, proxies, web filters, and other network security controls.

IP addresses to whitelist

Whitelist all 23 addresses. Opensense added three addresses on April 1, 2023, and two more on January 1, 2025.
