I have the strange habit to look up my external IP and to display it in the conky instance on my desktop (see `here <https://cobra.pdes-net.org/posts/soho-system-monitoring.html>`_ for an example). So far, I've got this IP directly from my Fritz!Box 7170, but the command I've used doesn't work with the new box (a `7590 <https://cobra.pdes-net.org/posts/new-neuland.html>`_). I thus had to find a new way to get my IP.

There are plenty of websites returning the IP upon a simple connection by curl:  

::

	curl icanhazip.com
	curl ifconfig.me
	curl ipecho.net/plain
	curl ifconfig.co
	curl ipinfo.io/ip 
	curl -s checkip.dyndns.org | sed -r 's#(.*: )([0-9.]*)(<.*)#\2#'

There's also at least one DNS server offering this service:

::

	dig +short myip.opendns.com @resolver1.opendns.com

But I would very much prefer a local solution as before. And it turns out that this solution exists: The package ``miniupnpc`` “enables applications to access the services provided by an UPnP ‘Internet Gateway Device’ present on the network. In UPnP terminology, MiniUPnPc is a UPnP Control Point.”

This package contains a command that retrieves the external IP from current Fritz!Boxes:

::

	cobra at blackvelvet in ~
	↪ external-ip 
	85.212.90.227

Bingo!
