Is it possible to run a code that searches IPConfig for the IP address then saves that to a text document or enters it into the prompt? I want to be able to plug my flash drive into a computer, run said batch file and either use that IP address or save it.

FULL code

@ECHO OFF
ECHO.


FOR /F "TOKENS=2* DELIMS=:" %%A IN ('IPCONFIG ^| FIND "IPv4"') DO FOR %%B IN (%%A) DO SET IPADDR=%%B
ECHO %IPADDR% > file.txt



:End

The previous code will store your local ip into file.txt
