The 169.254.xxx.xxx IP address space is reserved for self-assigning or link-local IP addresses. They are used when your device is not connected to any network at all or a network that has no DHCP server, so that devices can assign their own IP address. When these devices use Bonjour, they can create their own DNS name resolution on the network. This is useful when you are connected to a network that is completely isolated; you will be able to network to other devices and even see their share names and Bonjour advertised services.

RFC 3927 covers the details of this IP address space. Section 1.6 covers the “Alternate Use Prohibition” of this IP space.
