Run real netcat syntax against a safe, offline lab network - port-scan with -zv, grab service banners, and start a listener with -lvnp. No real socket is ever opened.
Ideal for: Network+ and CompTIA Security+ trainees learning netcat as the "Swiss Army knife" of networking before touching a real interface.
What you'll practice
Practice real nc flags (-z, -v, -l, -n, -p) against fictional lab hosts
Scan port ranges and grab believable service banners on open ports
Start a simulated listener and see how -e would be described, without ever executing anything
Save your session as a shareable practice report link
