IP_ADAPTER_DNS_SERVER_ADDRESS (Compact 2013)

3/26/2014

This structure stores a single DNS server address in a linked list of DNS server addresses for a particular adapter.

Syntax

typedef struct _IP_ADAPTER_DNS_SERVER_ADDRESS {
  union {
    ULONGLONG Alignment;
    struct {
      ULONG Length;
      DWORD Reserved;
    };
  };
  struct _IP_ADAPTER_DNS_SERVER_ADDRESS* Next;
  SOCKET_ADDRESS Address;
} IP_ADAPTER_DNS_SERVER_ADDRESS,
  *PIP_ADAPTER_DNS_SERVER_ADDRESS;

Members

• Alignment
  Reserved. Used by the compiler to align the structure.

• Length
  The length, in bytes, of this structure

• Reserved
  Reserved.

• Next
  A pointer to the next DNS server address structure in the list.

• Address
  The IP address for this DNS server entry. This member can be an IPv6 address or an IPv4 address.

Remarks

The IP_ADAPTER_ADDRESSES structure is retrieved by the GetAdaptersAddresses function. The FirstDnsServerAddress member of the IP_ADAPTER_ADDRESSES structure is a pointer to a linked list of IP_ADAPTER_DNS_SERVER_ADDRESS structures.

The SOCKET_ADDRESS structure is used in the IP_ADAPTER_DNS_SERVER_ADDRESS structure.

The header file organization has changed and the SOCKET_ADDRESS structure is defined in the Ws2def.h header file, which is automatically included by the Winsock2.h header file. On the Platform Software Development Kit (SDK), the SOCKET_ADDRESS structure is declared in the Winsock2.h header file. In order to use the IP_ADAPTER_DNS_SERVER_ADDRESS structure, the Winsock2.h header file must be included before the Iphlpapi.h header file.
