Syntax

C++
Copy 

typedef struct in6_addr {
  union {
    u_char  Byte[16];
    u_short Word[8];
  } u;
} IN6_ADDR, *PIN6_ADDR, FAR *LPIN6_ADDR;

Members

u
Byte

An IPv6 address formatted as an array of sixteen u_chars.

Word

Remarks

The in6_addr structure is used with IPv6 addresses.

The in6_addr structure is the IPv6 equivalent of the IPv4-based in_addr structure.

Note  The IN6_ADDR, PIN6_ADDR, and LPIN6_ADDR derived structures are only defined on the Windows SDK released with Windows Vista and later. The IN6_ADDR, PIN6_ADDR, and LPIN6_ADDR derived structures are defined in the In6addr.h header file. The in6_addr structure should be used on earlier versions of the Windows SDK.
