What IP address does a device automatically assign to itself when unable to obtain one from a DHCP server?

When a device is unable to obtain an IP address from a DHCP server, it utilizes a process known as Automatic Private IP Addressing (APIPA). In this process, the device automatically assigns itself an IP address from the link-local address range, which is specifically defined as 169.254.0.1 to 169.254.255.254.

This range is reserved by the Internet Engineering Task Force (IETF) for local communications without the need for a central DHCP server. This allows devices on the same local network to communicate with each other, even when there is no DHCP server available to assign them an address. Thus, when a device selects the address 169.254.0.1, it is complying with the specifications of APIPA to ensure that it can still function within a local network context.

The other choices do not align with this behavior. The IP addresses 192.168.1.1 and 192.168.0.1 are commonly used private addresses, but they do not represent what a device would assign to itself in the absence of DHCP. The address 169.254.0.0, on the other hand, is a network address and not an assignable IP for a device.
