1. Backup and recovery of network settings
Backup operation: Netsh dump >bak12.txt
Restore operation: Nesh exec Bak12.txt
2, with the command to change the IP, as follows:
C:/>netsh (enter setup mode)
Netsh>interface
Interface>ip
Interface Ip>set Address "Local Area Connection" Static 10.1.1.111 255.255.255.0 10.1.1.254
Interface Ip>exit
C:/>ipconfig (change and then use the ipconfig command to check to see if the change was successful)
Windows $ IP Configuration

4. Example 1: Switch different fixed IP at any time
Open Notepad, create a new file, and enter the following code in it:
netsh interface ip set address "Local Area Connection" static 192.168.0.10 255.255.255.0 192.168.0.1 1, click File | Save, enter "Home.cmd" in the open window (double quotation marks in the code must be entered) and save it on the desktop.
Similarly, create a office.cmd file in which to enter: netsh interface ip set address "Local Area Connection" static 192.168.1.11 255.255.248.0 192.168.0.1 1, save it as " Office.cmd "file. Later at home just double-click "Home.cmd" to quickly switch the IP address to 192.168.0.10, the subnet mask is 255.255.255.0, the gateway is 192.168.0.1, and the company then double-click "Office.cmd" The IP can be switched to 192.168.1.11, the subnet mask is 255.255.248.0, and the gateway is 192.168.1.1.
A few notes:
1. The IP address assigned by each company is different, the reader can set it by itself or ask the network management.
2. The "Local Area Connection" in the above command is the name of the NIC connection, you can double-click the Network connection icon in the Control Panel to see the name of the corresponding network card. If you have multiple NICs, simply modify the name of the "local connection" above and the IP, subnet mask, and gateway.
3. The last 1 of the above command is the set metric, the value is more professional, the user can be set to 1, regardless.
5. Example 2: Fixed/dynamic IP switching at any time
Create a Static.cmd file on the desktop and enter the appropriate code in it, such as the netsh interface ip set address "Local Area Connection" static 192.168.0.12 255.255.255.0 192.168.0.1 1, also create a dhcp.cmd file, where the following code is entered:
netsh interface ip set address "Local Area Connection" DHCP
Ipconfig/release
Ipconfig/renew
Double-clicking Static.cmd on the desktop later modifies the IP of the local area connection to 192.168.0.12, the subnet mask is 255.255.255.0, the gateway is 192.168.0.1, and double-clicking the dhcp.cmd file causes the local Area connection is set to dynamic IP immediately and the IP address is updated immediately from the DHCP server.
