Your network hosts are all set up to use DHCP. Which IP address indicates that a host was unable to locate a DHCP server?

Automatic Private IP Addressing (APIPA) is a TCP/IP standard that is used to automatically configure IP-based hosts that are unable to connect to a DHCP server. APIPA addresses are in the range 169.254.0.0/16. If you notice a computer with an IP address beginning with 169.254, it has been configured.
