I keep getting
arplookup 168.186.1.19 failed: host is not on local network
arplookup 168.186.1.19 failed: host is not on local network
arplookup 168.186.1.19 failed: host is not on local network
arplookup 168.186.1.19 failed: host is not on local network
arplookup 168.186.1.19 failed: host is not on local network
arplookup 168.186.1.19 failed: host is not on local network
arplookup 168.186.1.19 failed: host is not on local network

This is Odd! I dunt know this IP by any chance. and even its not in my 
region area!
  why the box keep complaining from this IP?
  Is it possible that someone on my LAN, are trying to use this IP by 
mistake?
  If yes, how would I know who and what?

  Or is it some hacking attempt.
  I know my server replying and saying NO im not this IP, nor on the same 
LAN,
  but this IP is from australia i belive and im waaaaay far from that 
region,
  any explains please?

  Marwan Sultan.
