What range of addresses is used for automatic private IP addressing?

Automatic Private IP Addressing (APIPA) is a feature used by devices on a local network to automatically assign themselves an IP address when no external DHCP server is available. The specific range designated for this purpose is 169.254.0.0 to 169.254.255.254.

When a device configured to use DHCP cannot obtain an address, it will select an address from this range and present it for its use. This allows devices to communicate on the local network even in the absence of a DHCP server, facilitating local connectivity.

Understanding this concept is crucial for network installers and technicians, as it helps in troubleshooting and configuring networks effectively. The other address ranges listed pertain to various classes of IP addresses, but they are not used for APIPA. Hence, the 169.254.0.0 to 169.254.255.254 range is the correct answer for automatic private IP addressing.
