NL_SUFFIX_ORIGIN enumeration (nldef.h)

  • Article

The IP_SUFFIX_ORIGIN enumeration specifies the origin of an IPv4 or IPv6 address suffix, and is used with the IP_ADAPTER_UNICAST_ADDRESS structure.

Syntax

typedef enum {
  NlsoOther = 0,
  NlsoManual,
  NlsoWellKnown,
  NlsoDhcp,
  NlsoLinkLayerAddress,
  NlsoRandom,
  IpSuffixOriginOther = 0,
  IpSuffixOriginManual,
  IpSuffixOriginWellKnown,
  IpSuffixOriginDhcp,
  IpSuffixOriginLinkLayerAddress,
  IpSuffixOriginRandom,
  IpSuffixOriginUnchanged = 1 << 4
} NL_SUFFIX_ORIGIN;

Constants

 
NlsoOther
Value: 0
NlsoManual
NlsoWellKnown
NlsoDhcp
NlsoLinkLayerAddress
NlsoRandom
IpSuffixOriginOther
Value: 0
The IP address suffix was provided by a source other than those defined in this enumeration.
IpSuffixOriginManual
The IP address suffix was manually specified.
IpSuffixOriginWellKnown
The IP address suffix is from a well-known source.
IpSuffixOriginDhcp
The IP address suffix was provided by DHCP settings.
IpSuffixOriginLinkLayerAddress
The IP address suffix was obtained from the link-layer address.
IpSuffixOriginRandom
The IP address suffix was obtained from a random source.
IpSuffixOriginUnchanged
Value: 1
The IP address suffix should be unchanged. This value is used when setting the properties for a unicast IP interface when the value for the IP suffix origin should be left unchanged.



Note  This enumeration value is only available on Windows Vista and later.

 

Remarks

The IP_SUFFIX_ORIGIN enumeration is used in the SuffixOrigin 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_SUFFIX_ORIGIN enumeration is defined in the Nldef.h header file which is automatically included by the Iptypes.h header file. In order to use the IP_SUFFIX_ORIGIN enumeration, the Winsock2.h header file must be included before the Iptypes.h header file.

Requirements
