Hi, I have a bunch of ipaddresses that i need to know the DNS names of. i have a script and it works great. the only problem is that i have to manually enter the IP. Could someone help to modify this script so it will get the IP from a txt file or something like that. My code is: @ECHO OFF SETLOCAL SET SCRIPTNAME=%~n0 IF "%1"=="" ECHO Incorrect Syntax - use: %SCRIPTNAME% IPADDRESS && GOTO :EOF FOR /F "tokens=3delims=: " %%I IN ('PING -n 1 %1 ^| FIND "Reply from"') DO ( SET IP=%%I FOR /F "tokens=2 delims=:" %%J IN ('NSLOOKUP %%I ^| FIND "Name:"') DO SET DNS=%%J ) IF NOT DEFINED IP @ECHO %1 is invalid or NETWORK error occurred. && GOTO :EOF @ECHO. IF NOT DEFINED DNS @ECHO %1 - invalid DNS name or DNS error occurred. && GOTO :EOF echo %TIME% >> DNS.log echo %DNS% >> DNS.log @ECHO%DNS% ENDLOCAL

The below script makes you able to use the native one as usual, i.e. ScriptName IPaddress or Scriptname @FileName where FileName is a text file with ONE IP on each line. Beware the script was not tested. @ECHO OFF SETLOCAL SET SCRIPTNAME=%~n0 IF "%1"=="" ECHO Incorrect Syntax - use: %SCRIPTNAME% IPaddress or @File_Of_IPaddresses && GOTO :EOF Set Param=%1 If not "%Param:~0,1%"=="@" GoTo :RUN Echo. Reading IP addresses from %Param:~1% For /F %%a in (%Param:~1%) Do ( Call :RUN %%a) Echo. List completed GoTo :EOF :RUN FOR /F "tokens=3delims=: " %%I IN ('PING -n 1 %1 ^| FIND "Reply from"') DO ( SET IP=%%I FOR /F "tokens=2 delims=:" %%J IN ('NSLOOKUP %%I ^| FIND "Name:"') DO SET DNS=%%J ) IF NOT DEFINED IP @ECHO %1 is invalid or NETWORK error occurred. && GOTO :EOF ECHO. IF NOT DEFINED DNS @ECHO %1 - invalid DNS name or DNS error occurred. && GOTO :EOF echo %TIME% >> DNS.log echo %DNS% >> DNS.log ECHO.%DNS%
