Answer 1

You simply cannot do that... moreover, the IP adress of a contact is something that doesn't exist in real world, the IP a user is using depends on where the contact is doesn't it ?

Answer 2

This gets the originating IP from the first email thread in you inbox:

  var thread = GmailApp.getInboxThreads(0,1)[0]; // get first thread in inbox
  var message = thread.getMessages()[0]; // get first message
  var rawMessage = message.getRawContent();
  var lines = rawMessage.split('\n');
  for each(line in lines){
    if(line.substring(0,'X-Originating-IP'.length)=='X-Originating-IP'){
      Logger.log(line);
    }
  }
