Free IP Scanner Help



Free IP scanner is a very fast IP scanner and port scanner. It is intended for both system administrators and general users to monitor and manage their networks. Powered with multi-thread scan technology, it can scan hundreds computers per second. It simply pings each IP address to check if it's alive, determines hostname, MAC address, NetBIOS information, scans ports, etc. The information obtained can be exported into a file as plain text file.

Quick Start Guide

Step 1: Run the program

Follow Start > All Programs > Free IP Scanner > Free IP Scanner.
Or just double click the Free IP Scanner icon on your Desktop.

Step 2: Select ip scan range and start scanning
Use two fields of IP Range to enter first and last IP addresses. The last IP address can be less than the first one - there is no problem with translating your input. To begin the scan, press the 'Start Scanning' button. When the program is scanning, this button becomes the 'Stop Scanning' button. Below at the picture there is the main program interface.
