Or for a bit of bash practice, you can do it yourself. A couple of years
ago, I needed to track a dynamic IP for a couple of months, until a
fixed one was organised. I ran this on the client's Linux server with a
cron job once an hour:
wget -qO- http://ipecho.net/plain | /usr/bin/mutt -s "IP report"

I did actually get a bit creative later, and automated the moving of
the address from the latest email into my workstation's /etc/hosts
file, but I made use of a web server, which you may not have in your own
network, and my IMAP processing script was in php. A semi-automatic
method would be to save the latest email as a text file, and run a bash
script to pick out the address and poke it into the local /etc/hosts.
