Nmap

 

A. Ping Scan (Check if host is up)

nmap -sn TARGET_IP

✔ Only checks if host is alive


TCP Port Scan (Default Scan)

nmap TARGET_IP


C. UDP Port Scan

nmap -sU TARGET_IP


✔ Slower
✔ Finds open UDP ports


D. OS Fingerprinting (Find Operating System)
nmap -O TARGET_IP


✔ Detects OS like Windows, Linux, etc.


E. Scan Specific Ports

nmap -p 80,443 TARGET_IP

✔ Scans only port 80 & 443
