Detailed explanation-1: -Automatic Private IP Addressing (APIPA) is a feature in operating systems (such as Windows) that enables computers to automatically self-configure an IP address and subnet mask when their DHCP server isn’t reachable. The IP address range for APIPA is 169.254. 0.1-169.254. 255.254, with the subnet mask of 255.255.

Detailed explanation-2: -0.1 through 169.254. 255.254. (I. It means you have not assigned a static IP address to your computer, and the computer can not connect to, or find a DHCP server to obtain an IP address.

Detailed explanation-3: -APIPA assigns a class B IP address from 169.254. 0.0 to 169.254. 255.255 to the client when a DHCP server is either permanently or temporarily unavailable. Designed for small non-routable networks, if a DHCP server becomes available later, the APIPA address is replaced with one from the DHCP server.

Detailed explanation-4: -If you see a 169.254. x.x address, it means that the DHCP server is not reachable. The PC will not work because there is not a router to or from that PC. Troubleshoot this by finding out why the PC cannot see the DHCP server.
