Get the external IP address from a Linux box

[André Rodier <andre@rodier.me>]

Hello,

I am looking for a native package on Debian, that can give me the
external IP address of the machine.

So far, I used internet sites, but I am sure there is a package that do
that properly, especially if one site is unreachable.

Something I can run from the command line, and that would return the
external IP address.

Thanks.
