<br>
I recently switched to CarryTel, and I'm getting disconnected quite often.<br>
So, I want to monitor my external IP, every minute. For this, I usually<br>
use <<a href="http://myexternalip.com/raw" rel="noreferrer" target="_blank">http://myexternalip.com/raw</a>>, but it has rate limit.<br>
<br>
What site do you use to get your external IP? I want to round-robin<br>
through these. Google gives you this when you search "what is my ip",<br>
but it's difficult to dig it out. Simpler, the better.<span class="m_5700580053022713522m_1055695808265999904HOEnZb"></span></blockquote></div></div></div></div></blockquote><div><br></div><div>There are a lot of services like this. Here's one I've used in the past:<br><br></div><div> $ curl <a href="http://ifconfig.co" target="_blank">ifconfig.co</a><br></div><div> xx.yyy.zz.www<br><br></div><div>It returns just an IP address, which is very useful (and low bandwidth). I have no idea if it has a rate limit.<br><br></div><div>Your problem if you're round-robin-ing several such sources will be consistency. Building on a previously mentioned idea, I'd suggest writing a function for each source that returns only the IP (or whatever information you're interested in).<br><br></div><div>So ... is the problem disconnection? The duration of the disconnection? The fact that your IP changes? I personally wouldn't be concerned if my IP changed (I don't run externally accessible services), so long as I have a connection. So I'd be logging a never-ending ping to some source like 8.8.4.4 (Google DNS) to determine how long and how often I was disconnected for. (I'm not really looking for answers to these questions, just suggesting things to think about.)<br></div><br></div>-- <br><div class="m_5700580053022713522gmail_signature" data-smartmail="gmail_signature">Giles<br><a href="https://www.gilesorr.com/" target="_blank">https://www.gilesorr.com/</a><br><a href="mailto:gilesorr@gmail.com" target="_blank">gilesorr@gmail.com</a></div>
