When a user starts PortExpert, he sees a list of all TCP or UDP ports that are active and connected to his remote IP address. A user can double-click on such an active connection to continue digging and learn more about that connection. The Freeze Time option can always be used to disable any connection.
The function can be used to learn more about the IP address location. It opens the whois.domaintools.com website when an IP address is selected in the active connection pool. By clicking on the Search Web function, a user can learn more about the current process that is accessing the Internet via an active TCP/UDP connection.
The Show System Process is another option that allows this user to check the currently active ports of OS files. Show Local Connection opens the current active UDP port connection and a user can select such a running process and read basic information about the process ID and protocol (TCP, UDP) used to connect, the local address and the remote address with the port number.
