What is Automatic Private IP Addressing (APIPA)

I believe all of you might noticed that your Windows Machine sometime will get IP address between 169.254.0.0 – 169.254.255.255.

Do you really know why your Windows Machine will get the IP between 169.254.0.0 – 169.254.255.255?

IP Address range 169.254.0.0-169.254.255.255 is referring to Automatic Private IP Addressing (APIPA).  The Internet Assigned Numbers Authority (IANA) has reserved 169.254.0.0-169.254.255.255 for Automatic Private IP Addressing.

In a scenario when there is no DHCP server on the network or the DHCP server is not available, Windows uses APIPA to automatically assign itself an IP address in the address range between 169.254.0.0 and 169.254.255.255. Because APIPA does not configure the computer with DNS and default gateway settings, computers with assigned APIPA addresses have limited networking functionality. APIPA can also be used for troubleshooting DHCP. If the network administrator notices that the computer has an address from the APIPA range, it is an indication that the computer cannot communicate with the DHCP server.
