IP Address of Specific Ethernet as CMD Variable

I need to check my ip address every 10 minutes and write it to a csv file, if it has changed. However, I have several network cards in use. How can I get IP address of a specific card in CMD using its MAC address?

See below for modification of response to another question by @mousio . It didn't work for me though!

@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
    )
)

See below for part of response for ipconfig /all

Solution

IPconfig is hard to parse because the needed information is distributed over several lines. Use the right tools. I recommend wmic:

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

Note: the format of the MAC address is different in wmic (colons instead of dashes). Don't forget to escape the =.

Edit: to separate IPv4 and IPv6 Addresses, just split the string with another for loop:

@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%

Edit (by Mosy): Code to accomplish all required tasks, i.e. write ip address in a csv file and update it every 10 minutes if it has changed:

Basically, there will be two batch files in the same path, the first one is called ip_main.bat and contains:

@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

The second batch file is called ip_writer.bat and contains

@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%
