# Get Subnet Groups

Retrieve subnet groups configured for event handler filtering.

> **✅ All code examples tested:** Verified against FortiAnalyzer v7.4.8, v7.6.4, v8.0.0.

## Overview

This endpoint retrieves subnet groups - useful for:
- Listing all configured subnet group definitions
- Auditing network grouping configurations
- Verifying event handler subnet assignments
- Documentation and compliance reporting
- Network organization analysis

Subnet groups simplify event handler configuration by allowing multiple subnets to be referenced as a single entity.
