## What it is
netspy is a fast, cross-platform Go CLI tool for discovering reachable intranet network segments from a compromised host. It supports ICMP, ping, ARP, TCP, and UDP probing modules with configurable CIDR ranges and concurrency.

## Use cases
- discover reachable subnets in an internal network
- probe which intranet CIDR ranges a host can reach
- fast network segment discovery during penetration tests
- scan internal networks via icmp arp tcp or udp
- map live network segments after gaining initial access
- find alive gateways in private ip ranges

## When to choose
- you need a small, fast, cross-platform binary for internal network segment discovery
- you want multiple probing protocols (icmp, arp, tcp, udp) in one tool
- you are doing authorized red team or penetration testing on an internal network

## When to avoid
- you need full port scanning or service fingerprinting rather than segment reachability
- you lack legal authorization for internal network probing
- you need a maintained tool with an explicit license - the repo has no license file
