NetworkSherlock is a powerful and flexible port scanning tool designed for network security professionals and penetration testers. With its advanced capabilities, NetworkSherlock can efficiently scan IP ranges, CIDR blocks, and multiple targets.
It stands out with its detailed banner grabbing capabilities across various protocols and integration with Shodan, the world’s premier service for scanning and analyzing internet-connected devices. This Shodan integration enables NetworkSherlock to provide enhanced scanning capabilities, giving users deeper insights into network vulnerabilities and potential threats.
By combining local port scanning with Shodan’s extensive database, NetworkSherlock offers a comprehensive tool for identifying and analyzing network security issues.

Example Usage
Basic Port Scan
Scan a single IP address on default ports:
python networksherlock.py 192.168.1.1
Custom Port Range
Scan an IP address with a custom range of ports:
python networksherlock.py 192.168.1.1 -p 1-1024
Multiple IPs and Port Specification
Scan multiple IP addresses on specific ports:
python networksherlock.py 192.168.1.1,192.168.1.2 -p 22,80,443
CIDR Block Scan
Scan an entire subnet using CIDR notation:
python networksherlock.py 192.168.1.0/24 -p 80
Using Multi-Threading
Perform a scan using multiple threads for faster execution:
python networksherlock.py 192.168.1.1-192.168.1.5 -p 1-1024 -t 20
Scanning with Protocol Selection
Scan using a specific protocol (TCP or UDP):
python networksherlock.py 192.168.1.1 -p 53 -P udp
Scan with Shodan
python networksherlock.py 192.168.1.1 --use-shodan
Scan Multiple Targets with Shodan
python networksherlock.py 192.168.1.1,192.168.1.2 -p 22,80,443 -V --use-shodan
Banner Grabbing and Save Results
Perform a detailed scan with banner grabbing and save results to a file:
python networksherlock.py 192.168.1.1 -p 1-1000 -V -s results.txt
Ping Check Before Scanning
Scan an IP range after performing a ping check:
python networksherlock.py 10.0.0.1-10.0.0.255 -c
