Set network configurations from the command line in Windows

Lets use the following criteria:

We will be setting up Local Are Connection

    IP        : 172.168.100.2
    MASK    : 255.255.255.0
    GW        : 172.168.100.1
    GW Metric    : 1

Here is the syntax for IPv4:

netsh interface show config
netsh interface ip set address name="Local Area Connection" static 172.168.100.2 255.255.255.0 172.168.100.1 gwmetric=1
