一、背景

为解决公司普通人员需要切换IP、DNS的情况，于是搞了个windows下的bat脚本，可以对有线网络、无线网络进行切换设置。

脚本内容

@echo off
title 多网络接口IP切换工具

:menu
cls
echo ============================
echo 请选择要配置的网络接口:
echo ============================
echo 1. 有线网络（以太网）
echo 2. 无线网络（Wi-Fi）
echo 3. 刷新DNS缓存
echo 4. 退出
echo ============================
set /p choice=请输入选项(1-3): 

if %choice%==1 goto wiredMenu
if %choice%==2 goto wirelessMenu
if %choice%==3 goto flushDns
if %choice%==4 goto end

:wiredMenu
cls
echo ============================
echo 选择有线网络的IP配置:
echo ============================
echo 1. 使用DHCP自动获取所有设置
echo 2. 使用DHCP自动获取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. 返回主菜单
