Explanation

APIPA (Automatic Private IP Addressing) assigns a self-configured address in the 169.254.x.x range when a device cannot reach a DHCP server. An APIPA address is a direct indicator that the workstation failed to obtain a lease from DHCP, meaning the DHCP service is unreachable, down, or out of available addresses. RADIUS (A) and AAA (C) deal with authentication, not IP assignment. DNS (D) resolves names but does not assign IPs.
