title: Is ServicePointManager.DefaultConnectionLimit by IP?
body: <p>I'm building a web crawler and the target site does not allow more than 2 concurrent connections from the same IP.</p>
  
  <p>My plan was: I would buy an EC2 with 4 additional elastic ip's to get data faster (would be 10 concurrent connections, 8 from additional IP's and 2 from the "main" IP).</p>
  
  <p>I would use the <code>BindIPEndPointDelegate</code> (took from <a href="https://stackoverflow.com/a/6165025/">here</a>) to set the source IP and then start download the pages.</p>
  
  <p>So here my question comes in: The DefaultConnectionLimit will be applied to <strong>each</strong> source IP or will be the entire application limited to 2 concurrent connections?</p>
