title: How can I retrieve a user's public IP address via Amazon API Gateway + Lambda (node)
body: <p>I'm currently writing a Node.js lambda function, in which I want to log the incoming requester's public IP address. I've been looking through both the API Gateway and Lambda docs all day, but haven't found a solution.</p>
  
  <p>Does the lambda <code>event</code> object include request metadata I can use to extract the user's IP?</p>
