# Opensense IP addresses for whitelisting

## Overview

:::note[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.
