I needed a simple tool that can preform a reverse dns lookup for a given IP address or for a range of IP’s in order to find its PTR.

Usually I use Linux which has several tools for querying DNS, One of my favourite tools is the “host” command which can be used for this task:

root@bt">root@bt:~# host domain name pointer

Along with some bash scripting it can be used for checking multiple IP’s

I really needed a tool that can do the same on the Windows OS, so i decided to write Resolver…
