You need to use Wireshark. netstat is only for looking at what ports are open in that instant.
Bzzt wrong. While Wireshark, if you know how to use it, will provide this info as well, netstat will do the same. We're talking TCP here, so successful connections, even if terminated, will linger around for a while in a "TIME_WAIT" or "CLOSE_WAIT" state.
Similarly, if you try to connect to the wrong IP (as in, there's no device at all under that IP), you'll see a "SYN_SENT" state via netstat.
