+title: Location Reference
+description: Complete technical specification for Location monitoring
+---
+
+## Overview
+
+OpenStatus monitors your endpoints from multiple global locations to ensure accurate uptime and latency reporting. Each monitoring location corresponds to a Fly.io region, with both IPv4 and IPv6 addresses available for each.
+
+You can use these locations to:
+- Configure region-specific checks
+- Allowlist monitoring IPs in your firewall
+- Understand where requests originate during synthetic monitoring
+
+### Fly.io Regions & Monitoring IPs
+
+Below is the complete list of regions used for monitoring, along with their associated IPv4 and IPv6 addresses.
