GetAddrInfoW不返回IPv6地址？

Question

当我nslookup使用"google.com"时，我得到以下内容：

Addresses:  2607:f8b0:400a:801::1001
          173.194.33.32
          173.194.33.36
          173.194.33.34
          173.194.33.37
          173.194.33.33
          173.194.33.46
          173.194.33.39
          173.194.33.41
          173.194.33.38
          173.194.33.40
          173.194.33.35

但是，当我致电GetAddrInfoW并传递L"google.com"时，我会收到以下信息：

173.194.33.41
173.194.33.39
173.194.33.46
173.194.33.33
173.194.33.37
173.194.33.38
173.194.33.40
173.194.33.34
173.194.33.35
173.194.33.36
173.194.33.32

IPv6地址在哪里？

编辑：如果我使用"localhost"的相同代码执行相同的查找，则输出为：

0000:0000:0000:0000:0000:0000:0000:0001
127.0.0.1

这更令人头疼。
