I am looking for a way to be notified of an IP address change,

synchronously or asynchronously. What is the equivalent to NotifyAddrChange in Windows or NETLINK in Linux?

Use the SystemConfiguration framework to register for notifications

of changes to the status of a network interface.

Also, see scutil(8). This provides a command-line interface to the functionality of the SystemConfiguration framework. The source is available on Apple's Darwin site, so you can see how you might use the APIs.
