Synthetic Monitoring Source Regions

Published April 5, 2023 | Last modified November 9, 2026

Overview

This reference guide contains source region information that helps you with the configuration of Synthetic Monitoring features within F5 Distributed Cloud Services.

Source IP addresses

Each Provider and Region source their monitors from specific IP addresses. In some cases, your environments may require knowledge of these IP addresses to allow request access from them.

F5 Distributed Cloud provider source regions

Source IP addresses for Regional Edge (RE) sourced monitors can be found on the Proxy reference page

Note: F5 recommends that you source monitors from infrastructure that is separate from where applications are hosted. However, if you require hosting and monitoring from the same RE, then the source IP address is 100.127.0.0/18 (CGNAT address space reserved by RFC6598).
