Examples

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.
