Change any windows IP configuration setting in CMD with this powerful tool NETSH

Show TCP/IP settings—The command

netsh interface ip show config

shows the system's current TCP/IP configuration settings. You can see whether the system is using DHCP or static addressing as well as view the system's current IP address, subnet mask, gateway address, and DNS servers.

Change network configuration—Netsh can change the current network configuration. The command

netsh interface ip set
  address "Local Area 
  Connection" static 
  192.168.0.10 255.255.255.0
  192.168.0.254

sets the IP address of the system configuration Local Area Connection to 192.168.0.10, the subnet mask to 255.255.255.0, and the gateway address to 192.168.0.254. This use of Netsh comes in handy for laptops that must switch between static and dynamic addressed networks.

Use a dynamic DHCP assigned address—The command

netsh interface ip set
  address "Local Area 
  Connection" dhcp

sets the IP address of the Local Area Connection system configuration to use DHCP addressing.

Change a DNS server address—When you change the system's IP address type, you almost always have to change the DNS server's address as well. The command

netsh interface ip set dns
  "Local Area Connection" 
  static 192.168.0.2

Dynamically assign the DNS server address—When you switch to dynamic DHCP addressing, you typically also want the DNS server address to be assigned dynamically. The command
netsh interface ip set dns 
"Local Area Connection" dhcp

sets the Local Area Connection interface to use a DHCP-assigned DNS address.

Configure a WINS server—Netsh also lets you configure WINS servers. The following command configures a system's Local Area Connection interface to use a WINS server that has the IP address 192.168.100.3.
netsh interface ip set wins 
  "Local Area Connection" 
  static 192.168.100.3


Work with other interfaces—Netsh works with DHCP, Internet Authentication Service (IAS), and RAS interfaces as well as the local network interface. The command
netsh dhcp dump > dhcpcfg.dat

dumps the local DHCP server's configuration to the dhcpcfg.dat file. You can use this file in conjunction with Netsh to recreate the DHCP server.

Work with remote systems—One of Netsh's best hidden features is its ability to work with remote systems. The command
netsh set machine remotecomputer

sets the current computer to a different system on the network.

 Save the current configuration—The Interface Dump subcommand saves your current network configuration and generates a script that you can use to regenerate the configuration. The command
netsh interface dump > 
  mycfg.dat

redirects the Dump command to the mycfg.dat file.

Restore network configuration—The Netsh Exec command runs a Netsh script file. The command
netsh exec mycfg.dat

restores to your system the network configuration data that the preceding sample command saved.
