+#  Nmap
+Nmap, short for "Network Mapper," is a powerful open-source tool used for network discovery and security auditing.
+It is designed to scan networks, identify hosts, services, and open ports, and create a map of the network topology. 
+
+##  Host Discovery
+
+Scan a specific subnet to discover live hosts:
+- `nmap IP/Range`
+
+Scan using hostnames to discover live hosts:
+- `nmap scanme.nmap.org`
+
+Use a simple ping scan to discover live hosts without port scanning:
+- `nmap -sn IP/Range`
+
+ARP ping scan
+- `nmap -sn -PR IP/Range`
+
+UDP ping scan
+- `nmap -sn -PU IP/Range`
+
+ICMP ECHO Ping scan/sweep
+- `nmap -sn -PE IP/Range`
+
+ACK Ping scan
+- `nmap -sn -PA IP`
+
+IP Protocol Ping scan
+- `nmap -sn -PO IP`
+
+
+##  Ports & Services Discovery
+
+Specific port scan
+- `nmap -p 21,80 IP` or `nmap -p 0-65535 IP` or `nmap -p- IP`
+
+Version Detection Scan
+- `nmap -sV -T4 IP`
+
+Default script scan
+- `nmap -sC -T4 IP`
+
+TCP connect scan
+- `nmap -sT -T3 -v IP`
+
+Half-Open Scan / Stealth Scan
+- `nmap -sS -v IP`
+
+Aggresive scan
+- `nmap -A IP`
+
+Xmas scan
+- `nmap -sX -T4 IP`
+
+
+##  Banner Grabbing
+
+OS detection scan
+- ` nmap -O IP`
+
+Nmap script os discovery
+- `nmap --script smb-os-discovery.nse IP`
+
+Aggresive scan
+- `nmap -A IP`
+
+##  Save output into a file
+
+Save Normal Output
+- `nmap -oN scan_results.txt target_ip`
+
+Save Grepable Output
+- `nmap -oG scan_results.gnmap target_ip`
+
+Save XML Output:
+- `nmap -oX scan_results.xml target_ip`
+
+Save All Formats:
+- `nmap -oA scan_results target_ip`
