In what scenario would a default IP address configuration of 169.254.x.x typically occur?

A default IP address configuration of 169.254.x.x occurs specifically when a device is unable to obtain an IP address from a DHCP server due to connectivity issues. This range of IP addresses, known as Link-Local addresses, is automatically assigned by the operating system when the device is set to obtain its address dynamically but fails to do so.

In a typical networking scenario, when a device tries to connect to a network, it first sends a broadcast message to seek a DHCP server in order to receive a configuration that includes its IP address. If the server is unavailable—whether due to network problems, misconfiguration, or a lack of DHCP servers in the network—the device resorts to assigning itself an address from the 169.254.x.x range. This allows for communication with other devices on the same local network segment that may also be using Link-Local addresses, facilitating some level of network functionality despite the absence of a centralized DHCP server.
