mitcu, я бы ещё добавил в твой скрипт смену днс:
@echo
setlocal

for /f %%i in ('wmic nic where "NetConnectionStatus=2" get NetConnectionID /value') do 1>nul set "%%i"

set /p ip= Ip adress
Set /p Mask= Set IPMask
Set /p GW= Set Gateway
set /p DNS1= set DNS1
set /p DNS2= set DNS2

netsh interface ip set address name=%NetConnectionID% source=static addr=%ip% mask=%Mask% static gateway=%GW%


netsh interface ip set dns name=%NetConnectionID% source=static addr=%DNS1% register=PRIMARY
netsh interface ip add dns name=%NetConnectionID% addr=%DNS2% index=2
pause
