Microsoft DOS netstat command
The netstat command is used to display the TCP/IP network protocol statistics and information.
The netstat.exe command is an external command available in the below Microsoft operating systems.
NETSTAT [-a] [-e] [-n] [-s] [-p proto] [-r] [interval]
|-a||Displays all connections and listening ports.|
|-e||Displays Ethernet statistics. This may be combined with the -s option.|
|-n||Displays addresses and port numbers in numerical form.|
|-p||proto Shows connections for the protocol specified by proto; proto may be TCP or UDP. If used with the -s option to display per-protocol statistics, proto may be TCP, UDP, or IP.|
|-r||Displays the routing table.|
|-s||Displays per-protocol statistics. By default, statistics are shown for TCP, UDP, and IP; the -p option may be used to specify a subset of the default.|
|interval||Redisplays selected statistics, pausing interval seconds between each display. Press CTRL+C to stop redisplaying statistics. If omitted, netstat will print the current configuration information once.|
Tip: Keep in mind that if you have network applications open, such as the Internet browser you're using to view this page, additional items will be listed when you run "netstat" and the "netstat -a" command. So you may see items from Computer Hope in your list. If you want a true listing of background Internet connections, close all programs and run the command. Finally, it is also normal to see one or more 0.0.0.0 and 127.0.0.1 addresses.
Displays all local network information. Below is an example of what may be displayed.
|Proto||Local Address||Foreign Address||State|
Displays all connections on the computers in numerical format, only displaying the local and foreign IP addresses.
Running netstat with a number after the command will continue to run the command until stopped. In this case netstat would be refreshed ever five seconds. To cancel press CTRL + C.
