Set IP to Windows 7 from command line

 netsh interface ip set address "connection name" static 192.168.0.101 255.255.255.0 192.168.0.1


NOTE: The default connection names are Local Area Connection for wired adapters and Wireless Network Connection for Wi-Fi adapters. The IP address order: client IP, subnet mask, and gateway IP.


Here’s how to configure the DNS addresses:


netsh interface ip add dns "connection name" 208.67.222.222


netsh interface ip add dns "connection name" 208.67.220.220 index=2


NOTE: Remember to replace the connection names and IP addresses.


 To dump the TCP/IP configuration:

    netsh -c interface dump > PATH_AND_FILENAME.txt


To import the TCP/IP configuration:

    netsh -f PATH_AND_FILENAME.txt
For setting dhcp



netsh interface ip set address "Local Area Connection" dhcp
