I have not done this but why not just dig or nslookup for the FQDN before
launching ez-ipupdate and then decide if it is needed?
something like
if (my_new_ip != nslookup(myhost.dyndns.org))
ez_ipupdate(my_new_ip);
that should cover most circumstances unless you are rebooting often,
getting a new address all the time and TTL's are longer than your reboot
interval.
