PortScan is a free utility/software to locate, monitor, and control any dynamic or static ports on any computer network adapter/portsmouth-like devices like routers, hubs, and so forth. PortScan also quickly finds all running devices on the network and automatically determines the IP address, service name, and opened services for each device. PortScan displays all opened ports and additional data such as MAC address, IP, port number, service name, port number, user name and password. PortScan uses up to 100 Threads for rapidly scanning large IP ranges. It is a free download from the internet.
PortScan works well with many operating systems including Windows 2021, XP, Window NT, Window Vista, and so forth. It detects open ports based on MAC address and IP addresses and displays all detected open/closed ports in a tree format. Each port has a status icon.
