[网络连接] 多网卡的IP地址备份还原批处理该怎么写？

@echo off
setlocal

REM 设置备份文件名
set BACKUP_FILE=%USERPROFILE%\Desktop\network_config_backup.txt

REM 获取当前的网络配置信息
ipconfig /all > %BACKUP_FILE%

REM 提取IP地址、子网掩码、默认网关和DNS服务器
for /f "tokens=2 delims=:" %%a in ('findstr /i "IPv4 Address" %BACKUP_FILE%') do set IP=%%a
for /f "tokens=2 delims=:" %%a in ('findstr /i "Subnet Mask" %BACKUP_FILE%') do set MASK=%%a
for /f "tokens=2 delims=:" %%a in ('findstr /i "Default Gateway" %BACKUP_FILE%') do set GATEWAY=%%a
for /f "tokens=2 delims=:" %%a in ('findstr /i "DNS Servers" %BACKUP_FILE%') do set DNS=%%a

REM 将提取的信息写入备份文件
echo IP Address: %IP% >> %BACKUP_FILE%
echo Subnet Mask: %MASK% >> %BACKUP_FILE%
echo Default Gateway: %GATEWAY% >> %BACKUP_FILE%
echo DNS Servers: %DNS% >> %BACKUP_FILE%

echo Network configuration has been backed up to %BACKUP_FILE%.

endlocal
pause

还原IP
@echo off
setlocal

REM 设置备份文件名
set BACKUP_FILE=%USERPROFILE%\Desktop\network_config_backup.txt

REM 检查备份文件是否存在
if not exist "%BACKUP_FILE%" (
    echo Backup file does not exist. Please make sure you have a valid backup file.
    pause
    exit /b
)

REM 从备份文件中读取网络配置
for /f "tokens=2 delims=:" %%a in ('findstr /i "IP Address" %BACKUP_FILE%') do set IP=%%a
for /f "tokens=2 delims=:" %%a in ('findstr /i "Subnet Mask" %BACKUP_FILE%') do set MASK=%%a
for /f "tokens=2 delims=:" %%a in ('findstr /i "Default Gateway" %BACKUP_FILE%') do set GATEWAY=%%a
for /f "tokens=2 delims=:" %%a in ('findstr /i "DNS Servers" %BACKUP_FILE%') do set DNS=%%a

REM 去除可能存在的空格
set IP=%IP:~1%
set MASK=%MASK:~1%
set GATEWAY=%GATEWAY:~1%
set DNS=%DNS:~1%

REM 设置网络配置
netsh interface ip set address "本地连接" static %IP% %MASK% %GATEWAY% 1
netsh interface ip add dns "本地连接" %DNS% index=1

echo Network configuration has been restored from %BACKUP_FILE%.

endlocal
pause
