rem eth //eth 爲網卡名稱
echo 1.檢測活動網卡...
rem 獲取網絡鏈接名稱

@(for /f "tokens=3*" %%a in ('netsh interface show interface^|more +2') do @echo,%%b)>"network.txt"
set j=0
for /f "tokens=*" %%i in (network.txt) do (

set gw=%ipduan%.1
rem netmasks //子網掩碼 
set netmasks=255.255.255.0
rem 最大和最小IP地址

echo 2.檢查ID配置...

echo 3.生成下一個ip地址...

    set /a j+=1
    set con!j!=%%i
    call set id=%%con!j!%%

echo --------
set /a newid=%id%+1

echo IP段分配已達上限:%ipduan%.%MAXID%！請從新修改nowid.txt文件或檢查IP地址
goto changeerror
) else (
echo %newid% > nowid.txt
echo 下一個編號爲:%newid%
)

rem ip //ip 爲你想更改的IP 
set ip=%ipduan%.%newid%
echo 下一個ip地址:%ip%
echo 下一個ip地址網關:%gw%
echo 下一個ip地址掩碼:%netmasks%
echo --------
echo 4.本機IP更改: %ip% 
rem 

netsh interface ipv4 set address %eth% static %ip% %netmasks% %gw% 
rem >nul
echo.
echo 5.驗證當前本機IP：

ipconfig -all >ipconfig.txt
type ipconfig.txt | find "%ip%" && goto success
:changeerror
echo 修改失敗，請手動分配IP地址!
goto :end
:success
echo 修改爲功
goto :end
