title: Resolve Hostname with just the IP available
body: <p>In my network there are plenty of devices (IPv4). Now there is a new device, I want to assign a IP, but when I assign it, there is a message: This IP is already used.</p>
  
  <p>Can someone tell me, how I can get the hostname?</p>
  
  <p>Already tried:
  <code>ping -a &lt;IP&gt;</code> (Result: no resolution of hostname)
  <code>nslookup  &lt;IP&gt;</code> (Result: Not found, "<em>Non-existent domain</em>".)
  <code>nbtstat -A &lt;IP</code>> (Result: I only get a resolution for my APIPA IP (169....))</p>
