--host 192.168.1.0
--host 192.168.1.0/24
--host custom-list.txt
--host 192.168.1.10,192.168.1.20,192.168.1.30
-i, --interface Specify the network interface
-s, --source Specify the source IP address
-P, --protocol Specify the protocol
-m, --maxhop Set max hop(TTL) for ping or traceroute
-T, --scantype Specify the scan-type
-t, --timeout Set timeout in ms - Example: -t 10000
-w, --waittime Set wait-time in ms (default:100ms) - Example: -w 200
-r, --rate Set send-rate in ms - Example: -r 1
-c, --count Set number of requests or pings to be sent
-S, --service Enable service detection
-O, --os Enable OS detection
-A, --async Perform asynchronous scan
-l, --list Use list - Example: -l custom-list.txt
-W, --wellknown Use well-known ports
-j, --json Displays results in JSON format.
