How to set the IP address, default gateway, and DNS server address using a BAT file?

It seems that you need to read the registry to determine the local connection, and then use netsh to modify it. I'm a novice.

There are plenty online. You can look for "ghost automatic ip bat". They all use netsh to change IP and others, but it's very imperfect.

I get the error that an invalid interface "Local Area Connection" is specified when I use netsh to modify the IP in WIN2000!

See if the Remote Registry service is turned off. If it's turned off, it won't work. Also, check if the network card's interface name is correct!!! If the Remote Registry service is turned off, the NETSH command won't run successfully.

I exported the contents under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces in the registry after setting up the IP, and then imported it when needed to set the IP, but the content seems a bit more!

netsh interface ip set address name="Local Area Connection" source=static addr=%IPAddress% mask=255.255.255.0 gateway=192.168.0.1 gwmetric=1

What the user said on the 7th floor is correct. If you want to add DNS, when replying to the second one, you need to pay attention to adding index=2.

@echo off
rem eth //eth is the name of the network card, which can be queried in Network Connections, such as "Local Area Connection"
set eth="Local Area Connection"
rem ip //ip is the IP you want to change
set ip=*.*.*.*
rem gateway //gateway is the gateway address
set gateway=*.*.*.*
rem netmasks //netmasks is the subnet mask
set netmasks=255.255.255.0
rem dns //dns is the preferred DNS
set dns=*.*.*.*
rem dns2 //dns2 is the alternate DNS
set dns2=*.*.*.*
echo Changing the local IP to: %ip%, please wait...
rem
if %gateway%==none netsh interface ip set address %eth% static %ip% %netmasks% %gateway% > nul
if not %gateway%==none netsh interface ip set address %eth% static %ip% %netmasks% %gateway% 1 > nul
if %dns%==none netsh interface ip set dns %eth% static %dns%> nul
if not %dns%==none netsh interface ip set dns %eth% static %dns%> nul
if %dns2%==none netsh interface ip add dns %eth% %dns2%> nul
if not %dns2%==none netsh interface ip add dns %eth% %dns2% 2> nul
echo.........................
echo Checking current local IP:
ipconfig
echo.........................
Successfully changed the local IP to %ip%!

close

The upstairs made it too complicated. Generally, in a local area network where only the last byte of the IP address is different, you can use the following BAT file!
@echo off
set /p a=Please enter the last byte of the IP address
netsh interface ip set address "Local Area Connection" static The first three bytes of the IP to be changed.%a% Subnet mask Gateway address 1
netsh interface ip set dns "Local Area Connection" static Preferred DNS
netsh interface ip add dns "Local Area Connection" Alternate DNS
netsh interface ip add dns "Local Area Connection" Alternate DNS
