Open Port Checker

Checks the connectivity status of specified network ports on a given IP address. Users input an IP range and a set of port numbers, allowing the tool to scan them sequentially. The application attempts to establish communication with each designated port, reporting whether the connection is open or closed. This functionality helps users verify network accessibility and troubleshoot basic networking issues by confirming which services are actively listening on the target machine. Network administrators, developers, and security students utilize this utility for diagnosing connectivity problems and mapping out service availability. It assists in determining if a specific server or device is accepting incoming connections on expected ports.
