SCOPE_LEVEL enumeration (ws2def.h)

  • Article

The SCOPE_LEVEL enumeration is used with the IP_ADAPTER_ADDRESSES structure to identify scope levels for IPv6 addresses.

Syntax

typedef enum {
  ScopeLevelInterface = 1,
  ScopeLevelLink = 2,
  ScopeLevelSubnet = 3,
  ScopeLevelAdmin = 4,
  ScopeLevelSite = 5,
  ScopeLevelOrganization = 8,
  ScopeLevelGlobal = 14,
  ScopeLevelCount = 16
} SCOPE_LEVEL;

Constants

 
ScopeLevelInterface
Value: 1
The scope is interface-level.
ScopeLevelLink
Value: 2
The scope is link-level.
ScopeLevelSubnet
Value: 3
The scope is subnet-level.
ScopeLevelAdmin
Value: 4
The scope is admin-level.
ScopeLevelSite
Value: 5
The scope is site-level.
ScopeLevelOrganization
Value: 8
The scope is organization-level.
ScopeLevelGlobal
Value: 14
The scope is global.
ScopeLevelCount
Value: 16

Remarks

The SCOPE_LEVEL enumeration is used in the ZoneIndices member of the IP_ADAPTER_ADDRESSES structure.

On Windows Vista and later as well as on the Microsoft Windows Software Development Kit (SDK), the organization of header files has changed and the SCOPE_LEVEL enumeration type is defined in the Ws2def.h header file. Note that the Ws2def.h header file is automatically included in Winsock2.h, and should never be used directly.

Requirements
