rem eth //eth 为网卡名称
echo 1.检测活动网卡...
rem 获取网络连接名称

@(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 /a j+=1
  set con!j!=%%i
  call set eth=%%con!j!%%
)
echo 当前活动网卡名称为：%eth%
set ipduan=149.32.49
rem gw //网关
set gw=%ipduan%.1
rem netmasks //子网掩码 
set netmasks=255.255.255.0
rem 最大和最小IP地址
set MAXID=205
set MINID=5

echo 2.检查ID配置...
set j=0
for /f "tokens=*" %%i in (nowid.txt) do (
  set /a j+=1
  set con!j!=%%i
  call set oldid=%%con!j!%%
)

if %oldid% LSS %MINID% (
echo 检查nowid.txt文件,ID:%oldid%不能小于%MINID%
goto changeerror)

echo 3.生成下一个ip地址...

set j=0
for /f "tokens=*" %%i in (nowid.txt) do (
  set /a j+=1
  set con!j!=%%i
  call set id=%%con!j!%%
)
echo --------
echo 上一个编号为:%id%
echo 上一个ip地址为:%ipduan%.%id%
echo --------
set /a newid=%id%+1
if %newid% GTR %MAXID% (
echo IP段分配已达上限:%ipduan%.%MAXID%！请重新修改nowid.txt文件或检查IP地址
goto changeerror
) else (
echo %newid% > nowid.txt
echo 下一个编号为:%newid%
)

rem ip //ip 为你想更改的IP 
set ip=%ipduan%.%newid%
echo 下一个ip地址:%ip%
echo 下一个ip地址网关:%gw%
echo 下一个ip地址掩码:%netmasks%
echo --------
echo 4.本机IP更改: %ip% 
rem 

netsh interface ipv4 set address %eth% static %ip% %netmasks% %gw% 
rem >nul
echo.
echo 5.验证当前本机IP：

ipconfig -all >ipconfig.txt
type ipconfig.txt | find "%ip%" && goto success
:changeerror
echo 修改失败，请手动分配IP地址!
goto :end
:success
echo 修改成功
goto :end
:end
