Batch Ping Scan and Name Resolution

It's not fancy, but if you can't "import" any tools to a windows system this will do a basic job of finding hosts and resolving their names.

Quick, simple, uses nothing but built in components in the windows system.

@echo off
Title Scan
mode con: cols=20 lines=5
echo    Enter Network:
echo [Example 192.168.1]
set /p network=
mode con: cols=60 lines=254
title Scanning Network %network%.0/24
echo Scanning...
for /L %%i in (1,1,255) do ping -n 1 -w 60 %network%.%%i | find /i "reply" >> ~temp1
for /f "tokens=3 delims=: " %%i in (~temp1) do echo %%i >> ~temp2
del /f /q ~temp1 > nul
title Resolving Network %network%.0/24
for /f %%i in (~temp2) do for /f "tokens=2 delims=: " %%g in ('nslookup %%i 2^>nul ^| find /i "name"') do echo %%i %%g
for /f %%i in (~temp2) do for /f "tokens=1 delims=: " %%g in ('nslookup %%i 2^>^&1 ^| find /i "***"') do echo %%i Hostname Lookup Failed
del /f /q ~temp2 > nul
