一、背景
為解決公司普通人員需要切換IP、DNS的情況，于是搞了個windows下的bat腳本，可以對有線網絡、無線網絡進行切換設置。
腳本內容
@echo off
title 多網絡接口IP切換工具:menu
cls
echo ============================
echo 請選擇要配置的網絡接口:
echo ============================
echo 1. 有線網絡（以太網）
echo 2. 無線網絡（Wi-Fi）
echo 3. 刷新DNS緩存
echo 4. 退出

echo 選擇有線網絡的IP配置:

echo 1. 使用DHCP自動獲取所有設置
echo 2. 使用DHCP自動獲取IP地址 (固定DNS)
echo 3. IP配置 1 (192.168.66.101)
echo 4. IP配置 2 (192.168.1.101)
echo 5. 返回主菜單

pause
goto menu:flushDns
echo 正在刷新DNS緩存...
ipconfig /flushdns
echo DNS緩存已刷新。
pause
goto menu:end
echo 程序結束。
pause
exit
請用管理員運行的cmd輸入netsh interface ipv4 show interfaces
查看接口與腳本中的接口名稱是否一致
三、自定義腳本
請自行用記事本、notpad++、EmEditor、cudatex對bat腳本進行修改
有線修改位置if %wiredChoice%==
無線網絡修改位置if %wirelessChoice%==
四、使用
