Yes. In fact curl and grep can do the same thing (probably a bit simpler
too) - as long as the service exists and is free. On the other hand,
querying the router will always be there and be free. I just need to
ensure that the script containing the password is properly secured.

I've got this working on another router from a different manufacturer,
but not this particular one. The other router uses a normal
user-id:password syntax to log in. Then it's just a matter of
identifying the correct page to extract the ip address from.
