Code for obtaining the NIC name through batch processing (with a script for modifying the IP address, gateway, and DNS)

Copy codeThe Code is as follows: Use the ipconfig/all command to obtain the NIC name.
FOR/F "tokens = 2 *" % I IN ('ipconfig/all ^ | find/I "Ethernet adapter" ') DO set name = % j
: Use the for command to delete the colon following the NIC name.
FOR/F "tokens = 1 * delims =:" % I in ("% name %") do set Nic name = % I

Apply the above script to modify the DNS. For example, if the DNS server in China is paralyzed yesterday, change DNS to 202.96.199.132 to restore normal internet access.

Netsh-c interface ip add dns name = "% Nic name %" addr = 202.96.199.132 index = 1
Netsh-c interface ip add dns name = "% Nic name %" addr = 202.96.64.38 index = 2

Netsh-c interface ip set address name = "% Nic name %" source = static addr = 192.168.1.215 mask = 255.255.255.0
Netsh-c interface ip set address name = "% Nic name %" gateway = 192.168.1.1 gwmetric = 0
Netsh-c interface ip add dns name = "% Nic name %" addr = 202.96.209.20.index = 1
Netsh-c interface ip add dns name = "% Nic name %" addr = 202.96.209.5 index = 2

The test just now showed that if there are two NICs, the smaller number next to the local connection will be changed. For example, there are two local connections named "local connection 2" and "local connection 3", respectively, the script will modify the local connection 2 and cannot correctly identify the active network card, so it is not perfect. I can only wait for LZ to help improve it.
