windows - 作为 CMD 变量的特定以太网的 IP 地址

Question

我需要每 10 分钟检查一次我的 IP 地址并将其写入 csv 文件(如果它已更改)。但是，我有几个网卡在使用中。如何在 CMD 中使用其 MAC 地址获取特定卡的 IP 地址？

请参阅下文以修改对 another question 的回复通过 @mousio .虽然它对我不起作用!

@echo off
setlocal enabledelayedexpansion
set "MAC1=Physical Address"
set "MAC2=11-11-11-11-11-11"
set MACfound=false
for /f "usebackq tokens=1-2 delims=:" %%f in (`ipconfig /all`) do (
    set "item1=%%f"
    set "item2=%%g"
    if /i "!item1!"=="!MAC1!" if "!item2!"=="!MAC2!" (
        set MACfound=true
    ) else if not "!item1!"=="!item:IPv4 Address=!" if "!MACfound!"=="true" (
        echo Your IP Address is: %%g
        set MACfound=false
    )
)

请参阅下面的 ipconfig/all 部分响应

IPconfig 很难解析，因为所需的信息分布在多行中。使用正确的工具。我推荐wmic:

for /f "tokens=2 delims={}" %%a in ('wmic nicconfig where MACAddress^="11:11:11:11:11:11" get IPAddress /value') do echo %%~a

注意:wmic 中 MAC 地址的格式不同(冒号而不是破折号)。不要忘记转义 =。

编辑:分隔 IPv4 和 IPv6 地址，只需将字符串与另一个 for 循环分开:

@echo off
setlocal enabledelayedexpansion
for /f "tokens=2 delims={}" %%a in ('wmic nicconfig where MACAddress^="11:11:11:11:11:11" get IPAddress /value') do set "adresses=%%a"
echo All Addresses: %adresses%
for %%a in (%adresses%) do (
  echo %%~a|find "." >nul && set "ip4=!ip4!,%%~a
  echo %%~a|find ":" >nul && set "ip6=!ip6!,%%~a
)
echo IPv4-Address(es): %ip4:~1%
echo IPv6-Address(es): %ip6:~1%

编辑(由 Mosy 编写):完成所有必需任务的代码，即在 csv 文件中写入 ip 地址，如果它发生变化，则每 10 分钟更新一次:

基本上，同一路径下会有两个批处理文件，第一个名为 ip_main.bat 并包含:

@echo off
echo -- IP ADDRESS UPDATER, PLEASE DO NOT CLOSE! --
set parent=%~dp0%
CD "%parent%"
setlocal enabledelayedexpansion
for /f "tokens=2 delims={}" %%a in ('wmic nicconfig where MACAddress^="11:11:11:11:11:11" get IPAddress /value') do set "adresses=%%a"

for %%a in (%adresses%) do (
  echo %%~a|find "." >nul && set "ip4=!ip4!,%%~a
  echo %%~a|find ":" >nul && set "ip6=!ip6!,%%~a
)
set ip4_old=%ip4:~1%
set ip6_old=%ip6:~1%
set "ip4=%ip4*=%"
set "ip6=%ip6*=%"

call ip_writer > ip_file.csv

:loop
for /f "tokens=2 delims={}" %%a in ('wmic nicconfig where MACAddress^="11:11:11:11:11:11" get IPAddress /value') do set "adresses=%%a"

for %%a in (%adresses%) do (
  echo %%~a|find "." >nul && set "ip4=!ip4!,%%~a
  echo %%~a|find ":" >nul && set "ip6=!ip6!,%%~a
)
set ip4_new=%ip4:~1%
set ip6_new=%ip6:~1%
set "ip4=%ip4*=%"
set "ip6=%ip6*=%"

if not "%ip4_new%"=="%ip4_old%" (
    call ip_writer > ip_file.csv
    set ip4_old=%ip4_new%
)

set "ip4_new=%ip4*=%"    

timeout 600 /nobreak > nul
goto loop

第二个批处理文件称为 ip_writer.bat 并包含

@echo off
set parent=%~dp0%
CD "%parent%"
setlocal enabledelayedexpansion
for /f "tokens=2 delims={}" %%a in ('wmic nicconfig where MACAddress^="11:11:11:11:11:11" get IPAddress /value') do set "adresses=%%a"
rem echo All Addresses: %adresses%
for %%a in (%adresses%) do (
  echo %%~a|find "." >nul && set "ip4=!ip4!,%%~a
  echo %%~a|find ":" >nul && set "ip6=!ip6!,%%~a
)
set ip4=%ip4:~1%
set ip6=%ip6:~1%

echo ip4_address
echo %ip4%
