批处理改DNS(推荐)：

复制代码 代码如下:

@echo off

::判断本地连接 赋值a

for /f "tokens=3,4 delims== " %%i in ('ipconfig ^|findstr /r "本"') do echo %%i %%j >DNS.txt

for /f "tokens=1 delims==:" %%d in (DNS.txt) do set a=%%d

::请根据实际情况更改下面三行

echo 开始更改主dns

netsh interface ip set dns name="%a%" source=static addr=202.96.128.116

echo 完成

echo 开始更改副dns

netsh interface ip add dns "%a%" 202.96.128.86 index=2

del DNS.txt

exit

建议再加一个

echo 删除原始DNS

netsh interface ip del dns name="%a%" all

否则原先有DNS的就修改不了啊嘿嘿
