title: DHCP IP discovery, offer, request, ack
body: <p>Why does my DHCP server use my old ip adress as destination?</p>
  
  <p>0.0.0.0 - 255.255.255.255 -> discovery</p>
  
  <p>192.168.0.1 - <strong>192.168.0.100</strong> -> offer</p>
  
  <p>0.0.0.0 - 255.255.255.255 -> request</p>
  
  <p>192.168.0.1 - <strong>192.168.0.100</strong> -> ACK</p>
  
  <p>Normally it should use 255.255.255.255.
  Can someone help?</p>
