It's called "local link" and is what happens when your computer is not configured with a static IP address and cannot find a DHCP server. It assigns itself an address in the 169.254.0.0/16 range. It's a non-routable IP and is supposed to allow computers in the same network to communicate with one another, but I've never seen this work (mostly since I've only ever seen this happen when one PC's network card/cable went bad and the rest of the network were still on their designated network).

APIPA - "Short for Automatic Private IP Addressing. With APIPA, DHCP clients can automatically self-configure an IP address and subnet mask when a DHCP server isn't available. When a DHCP client boots up, it first looks for a DHCP server in order to obtain an IP address and subnet mask. If the client is unable to find the information, it uses APIPA to automatically configure itself with an IP address from a range that has been reserved especially for Microsoft. The IP address range is 169.254.0.1 through 169.254.255.254. The client also configures itself with a default class B subnet mask of 255.255.0.0. A client uses the self-configured IP address until a DHCP server becomes available.

The APIPA service also checks regularly for the presence of a DHCP server (every five minutes, according to Microsoft). If it detects a DHCP server on the network, APIPA stops, and the DHCP server replaces the APIPA networking addresses with dynamically assigned addresses.

APIPA is meant for nonrouted small business environments, usually less than 25 clients."
