我通过向具有 IPv6 的 Ubuntu 14.04.3 LTS 服务器添加 OpenVPN 隧道,在我的 Ubuntu 14.04.3 LTS 笔记本电脑上添加了 IPv6。我在 IPv6 和 IPv4 上都使用伪装。
使用 StackExchange 过去会定期更新更新/新问题的计数,我可以单击并加载它们,而无需重新加载整个页面。现在它已经不存在了。
我没有看到我检查的一些 StackExchange 主机的任何 AAAA 记录。

知道我打破了什么吗?
是的,这看起来很奇怪,所以我想知道。

所有不显示 ipv6 地址的网站都会有这个问题。可能堆栈交换未在 IPV6 上运行:
root@ijaz-HP-EliteBook-8560p:~# host www.google.com
www.google.com has address 216.58.210.68
www.google.com has IPv6 address 2a00:1450:4009:811::2004
root@ijaz-HP-EliteBook-8560p:~# host www.ncp.edu.pk
www.ncp.edu.pk has address 111.68.96.165
www.ncp.edu.pk has IPv6 address 2400:fc00:854a:aaaa:700d:d110:e593:8d00
root@ijaz-HP-EliteBook-8560p:~# host stackexchange.com
stackexchange.com has address 104.16.116.182
stackexchange.com has address 104.16.119.182
stackexchange.com has address 104.16.118.182
stackexchange.com has address 104.16.115.182
stackexchange.com has address 104.16.117.182
为什么它没有显示任何 ipv6 地址。
