Connection view setup
Right-click a connection to see additional options that include:
Resolve host names—If possible, all network addresses are displayed in DNS format, not in the numeral IP address format.
Show only TCP connections—The list only displays connections that belong to the TCP protocol suite.
Show listening connections—Select this option to only display connections where no communication is currently established, but the system has opened a port and is waiting for a connection.
Show connections within the computer—Select this option to only show connections, where the remote side is a local system – so-called localhost connections.
