|REG_SZ||IP address, in dotted decimal format||0.0.0.0|
Stores the IP address assigned to this interface by the IP autoconfiguration feature.
Autoconfiguration allows TCP/IP to configure an interface even when it cannot locate a DHCP server. If an attempt to locate a DCHP server fails, TCP/IP 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 its attempts to locate a DHCP server and abandons the autoconfiguration process if one is located.
This entry is used only when IP autoconfiguration is enabled, that is, the value of IPAutoconfigurationEnabled is 1.
Do not change the value of this entry. If you do, the IP address assigned to the interface might not be reliable.
