What does netstat do and what is netstat used for?

Netstat provides information about current connections to and from your PC and the configuration of your network.

It is a great tool to use in order to help you find network problems and performance problems related to network connections.

To use netstat open a command line window (such as 'cmd' on windows) and type netstat. This will show you your active connections. To see what the command line options are for netstat type -h (unix/linux) or /? after the command.

The most common netstat parameters are:

  • netstat -a : displays all active connections and ports being used
  • netstat -b : lists the names of the programs on your PC that are making connections
  • netstat -e : shows you how much data is being sent and received via your network connection
  • netstat -r : Shows you the network routing configuration of your router

Last word

Netstat is a useful tool to help you investigate network problems and to view statistical information about what programs are running on your computer which are currently making network (and internet) connections, how much data they are sending and receiving, and to whom.
