<h2>What is this?</h2>

<p>This tool allows you to find "good" peerings for dn42, by measuring the
latency from various points in the network towards you.</p>

<h2>How does it work?</h2>

<p>
  <ol>
    <li>you enter your (Internet) IP address or hostname</li>
    <li>various routers participating in dn42 will ping you over the Internet</li>
    <li>after a short while, you get back all the latency results</li>
    <li>you can then peer with people close to you (low latency)</li>
  </ol>
</p>

<h3>Launch a measurement</h3>

<p>
<form action="/submit" method="POST">
<label for="target">Target:</label>
<input type="text" name="target" id="target" value="{{ request.remote_addr|ipaddress_pp }}"/><br />
<input type="checkbox" id="public" name="public" />
<label for="public">Public?</label><br />
<input type="submit" value="Launch" />
</form>
</p>

<p>If you mark your measurement as public, it will be displayed on the
home page below.  Note that the IP addresses of the target will be shown
alongside the result.</p>
