Masscan (owned subnets)
Ultra-fast port sweeps — useful for large home labs / multiple VLANs.
Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.
Never aim Masscan at networks you do not own.
When
You run multiple /24 lab VLANs and need a quick open-port census.
How
Rate-limit appropriately; scan only your ranges; verify with Nmap -sV.
Why
Speed for multi-segment home labs without waiting all night.
Commands & usage
sudo masscan 192.168.0.0/16 -p1-1000 --rate 500 -oL home-masscan.txt
sudo masscan 10.10.10.0/24 -p80,443,22,445 --rate 200
Commands are educational examples. Adapt hosts, paths, and rates to your authorized scope.
