Script when dhcp address changes?

I know I saw this once before, but I failed in my search attempts to find it. If I want to run some script anytime dhcp changes my address, how do I do it?

Depends on the dhcp client

For dhcpcd-4.0.0-beta5 you can create /etc/dhcpcd.hook which is included in the script dhcpcd runs every time dhcpcd gets (or loses) an address. See dhcpcd-run-hooks man page for details.

For dhclient you can do a similar thing. See the file /sbin/dhclient-script on how to interact with it.
