The home PC that I'd be trying to contact has a 192.168.n.n IP address
given to it by my primary router. But the router's external address is
obtained by its DHCP client talking to my ISP's DHCP server. It's not
obvious to me how to query the router's client except by logging in to
the router's web interface and reading the number from the screen.
(It's a $38 consumer grade.)

Even if it were easy, the benefit of sending an email out every day is
that it indicates the server is still up. (I'm assuming it would be
home alone.)

Cheers,
David.
