2 minutes to read

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

Syntax

typedef enum  {
  ScopeLevelInterface,
  ScopeLevelLink,
  ScopeLevelSubnet,
  ScopeLevelAdmin,
  ScopeLevelSite,
  ScopeLevelOrganization,
  ScopeLevelGlobal,
  ScopeLevelCount
} SCOPE_LEVEL;

Constants


`ScopeLevelInterface` The scope is interface-level.
`ScopeLevelLink` The scope is link-level.
`ScopeLevelSubnet` The scope is subnet-level.
`ScopeLevelAdmin` The scope is admin-level.
`ScopeLevelSite` The scope is site-level.
`ScopeLevelOrganization` The scope is organization-level.
`ScopeLevelGlobal` The scope is global.
`ScopeLevelCount`

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.
