NL_DAD_STATE enumeration (nldef.h)

  • Article

The IP_DAD_STATE enumeration specifies information about the duplicate address detection (DAD) state for an IPv4 or IPv6 address.

Syntax

typedef enum {
  NldsInvalid,
  NldsTentative,
  NldsDuplicate,
  NldsDeprecated,
  NldsPreferred,
  IpDadStateInvalid = 0,
  IpDadStateTentative,
  IpDadStateDuplicate,
  IpDadStateDeprecated,
  IpDadStatePreferred
} NL_DAD_STATE;

Constants

 
NldsInvalid
NldsTentative
NldsDuplicate
NldsDeprecated
NldsPreferred
IpDadStateInvalid
Value: 0
The DAD state is invalid.
IpDadStateTentative
The DAD state is tentative.
IpDadStateDuplicate
A duplicate IP address has been detected.
IpDadStateDeprecated
The IP address has been deprecated.
IpDadStatePreferred
The IP address is the preferred address.

Remarks

The IP_DAD_STATE enumeration is used in the DadState member of the IP_ADAPTER_UNICAST_ADDRESS structure.

On the Microsoft Windows Software Development Kit (SDK) released for Windows Vista and later, the organization of header files has changed and the IP_DAD_STATE enumeration is defined in the Nldef.h header file which is automatically included by the Iptypes.h header file. The Nldef.h and Iptypes.h header files should never be used directly.
