Asuuming you're talking about an interface that is controlled by DHCP:do
a search on /etc/dhclient-exit-hooks.

read the manpage about your dhcp client. Maybe it will run a script
for you when the ip address changes.

Please read http://www.catb.org/~esr/faqs/smart-questions.html
Always provide you distro and release when posting questions.
It may help you get getter answers.

Your dhcp client may be able to run a script, whenever the address changes.
dhcpcd can.
