The Role of APIPA in Windows IP Address Assignment. Automatic Private IP Addressing (APIPA) is a DHCP failover mechanism for local Internet Protocol version 4 (IPv. Microsoft Windows. With APIPA, DHCP clients can obtain IP addresses when DHCP servers are non- functional. APIPA exists in all modern versions of Windows including Windows 1. How APIPA Works. Networks set up for dynamic addressing rely on a DHCP server to manage the pool of available local IP addresses. Whenever a Windows client device attempts to join the local network, it contacts the DHCP server to request its IP address. If the DHCP server stops functioning, a network glitch interferes with the request, or some issue occurs on the Windows device, this process can fail. When the DHCP process fails, Windows automatically allocates an IP address from the private range 1. Using ARP, clients verify the chosen APIPA address is unique on the network before deciding to use it. IP addresses that are assigned to a DHCP client in a Windows XP environment are marked as BAD.

In Windows utilities like ipconfig, this option is also called . They indicate network troubleshooting is required to identify and resolve the issue(s) preventing DHCP from working properly. Limitations of APIPAAPIPA addresses do not fall into any of the private IP address ranges defined by the Internet Protocol standard but still are restricted for use on local networks only. Like private IP addresses, ping tests or any other connection requests from the Internet and other outside networks cannot be made to APIPA devices directly. APIPA configured devices can communicate with peer devices on their local network but cannot communicate outside of it. While APIPA provides Windows clients a usable IP address, it does not provide the client with nameserver (DNS or WINS) and network gateway addresses as DHCP does. Local networks must not attempt to manually assign addresses in the APIPA range else IP address conflicts will result. To maintain the benefit APIPA has of indicating DHCP failures, administrators should avoid using those addresses for any other purpose and instead limit their networks to use the standard IP address ranges. Change IP address and DNS servers using the Command Prompt. Changing TCP/IP settings using the GUI property is very easy and simple.
