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
