NETSH Command to Change from Static IP Address to DHCP
To switch the specified adapter from a static address to DHCP, type the following command:
netsh interface ip set address “Local Area Connection” dhcp
NOTE: Typing this command changes the interface named “Local Area Connection” to DHCP.
To display all of the adapters in the computer with their current IP addresses to determine the correct adapter name, type the following command:
Netsh interface ip show config
To change to a static address, type the following command:
netsh interface ip set address “Local Area Connection” static ipaddr subnetmask gateway metric
NOTE: Replace ipaddr with the static IP address, subnetmask with the subnet mask, gateway with the default gateway and, if necessary, metric with the appropriate metric. The following example changes the interface “Local Area Connection” to a static address of 192.168.0.10 with a subnet mask of 255.255.255.0, and the interface has a default gateway of 192.168.0.1 with a metric of 1:
Configure TCP/IP from the Command Prompt
With Netsh.exe you can easily view your TCP/IP settings. Type the following command in a Command Prompt window (CMD.EXE):
netsh interface ip show config
With Netsh.exe, you can easily configure your computer’s IP address and other TCP/IP related settings. For example:
The following command configures the interface named Local Area Connection with the static IP address 192.168.0.100, the subnet mask of 255.255.255.0, and a default gateway of 192.168.0.1:
netsh interface ip set address name="Local Area Connection" static 192.168.0.100 255.255.255.0 192.168.0.1 1
(The above line is one long line, copy paste it as one line)
Netsh.exe can be also useful in certain scenarios such as when you have a portable computer that needs to be relocated between 2 or more office locations, while still maintaining a specific and static IP address configuration. With Netsh.exe, you can easily save and restore the appropriate network configuration.

First, connect your portable computer to location #1, and then manually configure the required settings (such as the IP address, Subnet Mask, Default Gateway, DNS and WINS addresses).
Now, you need to export your current IP settings to a text file. Use the following command:
netsh -c interface dump > c:\location1.txt
When you reach location #2, do the same thing, only keep the new settings to a different file:
netsh -c interface dump > c:\location2.txt
You can go on with any other location you may need, but we’ll keep it simple and only use 2 examples.
Now, whenever you need to quickly import your IP settings and change them between location #1 and location #2, just enter the following command in a Command Prompt window (CMD.EXE):
netsh -f c:\location1.txt
netsh -f c:\location2.txt
and so on.
You can also use the global EXEC switch instead of -F:
netsh exec c:\location2.txt
Netsh.exe can also be used to configure your NIC to automatically obtain an IP address from a DHCP server:
netsh interface ip set address "Local Area Connection" dhcp
Would you like to configure DNS and WINS addresses from the Command Prompt? You can. See this example for DNS:
netsh interface ip set dns "Local Area Connection" static 192.168.0.200
and this one for WINS:
netsh interface ip set wins "Local Area Connection" static 192.168.0.200
Or, if you want, you can configure your NIC to dynamically obtain it’s DNS settings:
netsh interface ip set dns "Local Area Connection" dhcp
BTW, if you want to set a primary and secondary DNS address, add index=1 and index=2 respectively to the lines of Netsh command.
As you now see, Netsh.exe has many features you might find useful, and that goes beyond saying even without looking into the other valuable options that exist in the command.
