局域网自动识别机器名和MAC并生成文件的命令

更新版本：添加了MAC 地址 确定了设备唯一性

V1.1 局域网自动识别机器名和MAC并生成文件的批处理命令

@echo off
setlocal enabledelayedexpansion

REM 设置输出文件
set outputFile=network_info.txt

REM 清空或创建输出文件
echo Scanning network from 192.168.20.1 to 192.168.20.254... > %outputFile%
echo ========================================== >> %outputFile%

REM 循环遍历IP地址范围
for /L %%i in (1,1,254) do (
    set ip=192.168.20.%%i
    echo Checking IP: !ip!
    
    REM 使用nbtstat获取机器名和MAC地址
    nbtstat -A !ip! > temp.txt
    
    REM 从temp.txt中提取机器名和MAC地址
    set machineName=
    set macAddress=
    
    for /f "tokens=2 delims= " %%a in ('findstr /i "UNIQUE" temp.txt') do (
        set machineName=%%a
    )
    
    for /f "tokens=1 delims= " %%a in ('findstr /i "MAC Address" temp.txt') do (
        set macAddress=%%a
    )
    
    REM 如果找到机器名和MAC地址，则写入输出文件
    if not "!machineName!"=="" (
        echo IP: !ip! >> %outputFile%
        echo Machine Name: !machineName! >> %outputFile%
        echo MAC Address: !macAddress! >> %outputFile%
        echo -------------------------- >> %outputFile%
    )
    
    REM 删除临时文件
    del temp.txt
)

echo Scan completed. Results saved to %outputFile%
