I recently switched to CarryTel, and I'm getting disconnected quite often.
So, I want to monitor my external IP, every minute. For this, I usually
use <http://myexternalip.com/raw>, but it has rate limit.
What site do you use to get your external IP? I want to round-robin
through these. Google gives you this when you search "what is my ip",
but it's difficult to dig it out. Simpler, the better.There are a lot of services like this. Here's one I've used in the past:$ curl ifconfig.coxx.yyy.zz.wwwIt returns just an IP address, which is very useful (and low bandwidth). I have no idea if it has a rate limit.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).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.)
