How to batch lookup host name to IP address

If you use this method, it required Cygwin because Windows doesn't have a host command, otherwise REM for for line with host and unREM the line with ping

Have a text file with the host names. Save the batch file below to hosttoip.bat and execute like this

hosttoip.bat hoststolookup.txt hostoutput.txt


@echo off

setlocal

if "%~1"=="" echo Usage: %0 serverList [outfile]&goto :EOF
if not exist "%~1" echo %~1 does not exist&goto :EOF

set outFile=%~2

if "%~2"=="" set outFile=outfile.txt

if exist "%outFile%" del "%outFile%"

for /f "tokens=*" %%a in ('type "%~1"') do call :PROCESS "%%a"

echo Results in %outFile%

goto :EOF

:PROCESS

set ipAddr=Not found

for /f "tokens=3 delims= " %%r in ('host %~1|find /i "Address"') do set ipAddr=%%r

REM for /f "tokens=4 delims= " %%r in ('ping -n 1 %~1|find /i "Statistics"') do set ipAddr=%%r

echo %~1 %ipAddr% >>"%outFile%"
