Quick Scan Network
AI-generatedOverview
This node performs a quick network scan using the nmap command with the '-sn' option, which is used for ping scanning to discover live hosts on a specified network range. It is beneficial for quickly identifying active devices within a network without scanning ports, useful in network inventory, monitoring, or troubleshooting scenarios.
Use Case Examples
- Scan the local network 192.168.0.0/24 to find all active devices quickly using a fast ping scan.
- Use the node to perform a quick scan on a specified IP range to detect which hosts are up before performing more detailed scans.
Properties
| Name | Meaning |
|---|---|
| Target Network Range / Host / IP | Defines the target network range, host, or IP address to scan. |
| Aggressive Mode | Enables faster execution of the scan by using the '-T5' option in nmap. |
| Check Top Ports | Specifies the number of top ports to check, though not used in quick scan operation. |
| Host Discovery | Enables or disables host discovery; if disabled, uses '-Pn' to skip host discovery (not used in quick scan). |
| Put Result in Field | Specifies the name of the output field to store the scan results (not used in quick scan operation). |
Output
JSON
json- Each item contains JSON data representing a discovered host from the quick scan.
