title: 'IPAddress' does not name a type with Arduino library Ethernet2
body: <p>I have an Arduino Ethernet2 shield.
  I read it has some problem with the default library.</p>
  
  <p>I downloaded the Ethernet2 library from <a href="https://code.google.com/p/tinkerit/source/browse/#svn%2Ftrunk%2FEthernet2%20library%2FEthernet2" rel="nofollow noreferrer">Tinker</a>, put the folder in the Arduino libraries path and copied some missing files from the old Ethernet library.</p>
  
  <p>I tried the webserver example of the Ethernet library. However including the Ethernet2 library gives the error <code>'IPAddress' does not name a type</code>.</p>
  
  <p>Does anyone have the same problem?</p>
  
  <p>Thanks in advance</p>
