 I know I can do it the hard way -- parsing the results of ifconfig
 with regular expressions -- but I suspect there's a much easier way.

For most purposes, the easy way is to use the dhclient hooks scripts;
that way, you don't need to poll the values, either.  

man 8 dhclient-script for details, but my /etc/dhclient-exit-hooks
script is: 

if [ x$old_ip_address != x$new_ip_address ]; then
/usr/local/bin/noip
fi
