Cox (rhymes with "Cox") has been spontaneously switching my home IP

I want to use expect and lynx to write a script that logs into the
D-Link router as a browser does, navigates to the place where the WAN IP
address is shown, reads it, and sends me an email at work if it's
changed.
This isn't an answer to your lynx question (to that I'd say that cURL
may be the best way to script what you want), but I'll recommend another
solution to this problem - sign up for a DynDNS service. I use and
recommend http://www.dyndns.com/services/dns/dyndns/
They will provide a free DNS name for your home connection. You then
install a small software client
(http://www.dyndns.com/support/clients/unix.html) which sends any IP
changes to the DynDNS servers, which then in turn change the IP that
your DNS name points to. You may even find that the D-Link router has a
built-in DynDNS client. I know that some Linksys routers do, as do
firewall OSes like m0n0wall.
Then from work, you'll always be able to refer to a name like
'lanbarnes.homeip.net', which will magically always point to the correct
IP no matter how hard Cox tries to screw you up.
