Description
Stores the IP address that the IP autoconfiguration feature assigns to this interface.
Autoconfiguration allows TCP/IP to configure an interface even when it cannot locate a Dynamic Host Configuration Protocol (DHCP) server. If TCP/IP cannot locate DCHP server, it configures the interface by using IP addresses from the Microsoft reserved Class B network (169.254.0.0), subnet mask 255.255.0.0. During autoconfiguration, TCP/IP continues trying to locate a DHCP server, and it abandons autoconfiguration if it finds one.
