## Vulnerable Application

This Module will perform an ARP scan for a given IP range through a Meterpreter Session.

## Verification Steps
  1. Start msfconsole
  2. Get meterpreter session
  3. Do: ```use post/windows/gather/arp_scanner```
  4. Do: ```set SESSION <session id>```
  5. Do: ```run```

## Options

### RHOSTS

  The target address range or CIDR identifier.

### SESSION

  The session to run this module on.

### THREADS

  The number of concurrent threads.

## Scenarios

### Windows 7 (6.1 Build 7601, Service Pack 1).
