我的笔记本电脑有两个网络接口。以太网接口直接连接到我的提供商的边缘路由器。它通过 SLAAC 获取 IPv6 地址。我手动设置 IPv6 DNS 服务器。无线接口连接到不理解 IPv6 的 CPE 路由器。
如果禁用无线接口，我可以使用以太网接口毫无问题地访问 IPv6 互联网。
当两个接口都启用时我遇到了问题和无线接口通过 DHCP 获取其 IPv4 DNS 服务器。让我们看看两种情况。
无线接口通过 DHCP 获取 IPv4 DNS 服务器 - CPE 路由器 (192.168.0.1) 将其地址作为 DNS 服务器发送。在这种情况下，Windows 7 将不会执行 AAAA 查找。浏览器使用 IPv4 传输访问双栈网站。我无法使用域名访问仅支持 IPv6 的网站。我可以使用 IPv6 文字而不是域名访问支持 IPv6 的网站。
无线接口手动配置了 OpenDNS DNS 服务器 - Windows 7 使用 IPv6 传输（通过以太网）执行 AAAA 查找。一切正常。
我的双宿主设置绝对不是标准的。不过，这种行为对我来说非常奇怪。我的以太网接口中有一个有效的 IPv6 接口。为什么 Windows 在场景 #1 中不会尝试 AAAA 查找？
我已经包含了 ipconfig /all 和 netstat -rn 的输出。

答案1
我怀疑您的 IPv4 CPE 设备上的名称服务器/代理不支持 AAAA 记录或类似的东西。
尝试对 AAAA 记录执行 nslookup，看看是否真的没有任何结果：
Z:\>nslookup
Default Server: s01.lab.local
Address: 2001:DB8::ffff
> set type=aaaa
> www.facebook.com
Server: s01.lab.local
Address: 2001:DB8::ffff
Non-authoritative answer:
Name: www.facebook.com Address:
2a03:2880:2110:3f02:face:b00c::
如果是这种情况，请尝试使用支持 AAAA 记录的“静态”DNS 服务器。（例如谷歌的 8.8.8.8）
