Как в данном примере установить фиксированный адрес? Ардуина постоянно лезет в сеть и подымает адрес с DHSP

<code class="hljs sketch"><span class="hljs-comment">  For this example you need UIPEthernet library:
    <a data-cke-saved-href="https://github.com/UIPEthernet/UIPEthernet" href="https://github.com/UIPEthernet/UIPEthernet" target="_blank">https://github.com/UIPEthernet/UIPEthernet</a>

  Typical wiring would be (this is for Arduino UNO,
  search for correct wiring for your board):
   VCC -- 5V
   GND -- GND
   CS  -- D10
   SI  -- D11
   SCK -- D13
   SO  -- D12
   INT -- D2
