ifconfig would only work if you are directly assigned the public,
external IP. If you are behind eg. a router that does NAT, you would
only see the private IP internal to the local network.

I am not aware of any packages in the repos that has this kind of
functionality, but you could always just write a simple script around
the various sites that report your external ip.

It can be as simple as `curl ipinfo.io` (or your preferred site), you
could even try to have a script to try a few backups in case your
primary site happens to be unreachable.
