Advanced Port Scanner is a free network scanner that allows you to quickly locate open ports on network machines and collect versions of programmes that are executing on those ports. The application offers a simple interface and a lot of features.
Enter the IP address range you want to use ("IP" button in the toolbar will help you to set the IP-address range of your network).
Make a list of the ports you want to scan.
Select "Scan" from the drop-down menu. You'll obtain a list of the computers in the network once the scanning procedure is finished.
You can use PortQry.exe to search for open ports on a local or distant computer. Once portqry.exe has been downloaded and extracted to your computer, open a command prompt and run portqry.exe followed by a parameter from the executable's folder.
The purpose of port and network scanning is to figure out how IP addresses, hosts, and ports are organised so that open or vulnerable server locations can be identified and security levels can be assessed.
There is no federal statute prohibiting port scanning in the United States.
