Dom*_*Dom 8 networking dns windows-7 ipv6
非常简单,刚刚安装了 Win 7,SP1,64 位。没有 IPv6 访问。网络状态显示 IPv4:Internet。IPv6:无网络访问。
选择一个具有同时具有 IPv4 和 IPv6 地址的 DNS 服务器的域,例如www.hummerzines.com.au(dave.ns.cloudflare.com)。
从命令行执行 nslookup:
C:\Users\Dom\Desktop>nslookup hummerzines.com.au dave.ns.cloudflare.com
Server: dave.ns.cloudflare.com
Address: 173.245.59.109
Name: hummerzines.com.au
Addresses: 141.101.116.193
141.101.117.193

现在从 nslookup 内部执行 nslookup:
C:\Users\Dom\Desktop>nslookup
Default Server: resolv.internode.on.net
Address: 192.231.203.132
> hummerzines.com.au dave.ns.cloudflare.com
Server: dave.ns.cloudflare.com
Addresses: 2400:cb00:2049:1::adf5:3b6d

为什么 Windows 在这两种情况下表现不同?我认为它超时是因为它试图通过 IPv6 进行 DNS 查找?我还没有运行 WireShark 来证明/否认这一点。

您的计算机已尝试创建 Teredo 连接。Teredo 是几种 IPv6 过渡技术之一,所有这些技术都有各种缺点。Teredo 的缺点是它在明确设计的各种场景中不起作用,例如在 IPv4 NAT 设备后面。
因此,由于启用了 Teredo,您的计算机会认为它具有 IPv6 连接,但实际上该连接已断开。(网络状态图标使用完全不同的连接检查方法,但更准确。)
要解决此问题,请禁用 Teredo(同时禁用其他两个有问题的 6to4 和 ISATAP)。右键单击命令提示符并单击以管理员身份运行,然后运行以下命令:
netsh int ipv6 isatap set state disabled
netsh int ipv6 6to4 set state disabled
netsh int teredo set state disabled
