Network Scanner

Discover and identify devices on local or remote networks using nmap. Gathers IP addresses, hostnames (via reverse DNS), MAC addresses, and vendor identification.

Safety First: Includes built-in protection against accidentally scanning public IP ranges or networks without proper private routing — preventing abuse reports from hosting providers.

Requirements

• nmap - Network scanning (apt install nmap or brew install nmap)
• dig - DNS lookups (usually pre-installed)
• sudo access recommended for MAC address discovery
