netsh

In software, netsh, or network shell, is a command-line utility included in Microsoft's Windows NT line of operating systems beginning with Windows 2000. It allows local or remote configuration of network devices such as the interface.

A common use of netsh is to reset the TCP/IP stack to default, known-good parameters, a task that in Windows 98 required reinstallation of the TCP/IP adapter. In this mode log file must be provided, which will be filled with what values netsh affected.

Netsh, among many other things, also allows the user to change the IP address on their machine.

Starting from Windows Vista, one can also edit wireless settings (e.g. SSID) using netsh.

Example usage

Here are a few examples on how to use netsh to configure your network interface. Where 'local' is the name of the interface you want to configure.

netsh interface ip reset C:\resetlog.txt

Static IP address:

netsh interface ip set address local static 123.123.123.123 255.255.255.0 

Two static IP addresses:

netsh interface ip set address local static 123.123.123.123 255.255.255.0 
netsh interface ip add address local 234.234.234.234 255.255.255.0 

Dynamic IP address:

netsh interface ip set address name="Local Area Connection" source=dhcp

NETSH and IPv6

netsh can also be used to read information from the IPv6 stack.

To view the IPv6 addresses using NETSH:

netsh interface ipv6 show address
