客服信息

问：客服信息页面有何作用？

该页面旨在帮助用户简明扼要地说明其连接情况，必要时可以通过电话转述给运营商客服人员。由于最终受众是客服人员（而非普通用户），所以指导性的内容不多。

该页面的信息能够迅速传达：

各协议的状态
缓慢或超时警告
MTU警告
能否连通其他网站（以尽可能简要的方式）
对外的 IP 地址，以备技术支持之需
无法连通的网站（如果存在）

问：如何将用户引至客服信息页面？

打开下列任一网址即可转到客服信息页面并开始测试。其中有的网址可读性更强，有的则更适合电话交流。

test-ipv6.com/helpdesk (preferred for printed documentation)
test-ipv6.com/isp
helpdesk.test-ipv6.com
isp.test-ipv6.com

testv6.com/helpdesk (spoken English, "test vee six dot com slash helpdesk")
testv6.com/isp
helpdesk.testv6.com
isp.testv6.com

镜像网站可能没有那些花哨的网址，一般是这样的：

112

IPv4, plus Broken IPv6

IPv6 related attempts are timing out. This is not a quick fix. Verify the proper IPv6 address has been provisioned; verify the IPv6 route is correct. Check for unexpected or outdated firewalls and firewall rules. Other ideas are at broken.html. Of all the status codes, this is the one that suggests that users will have problems with many major web sites today, due to timeouts with IPv6.
(You can remember this code as the Emergency number for many parts of the world; much like America's 911).

IPv4 only

Provision working IPv6 to the user; ensure the user has a modern home router and a modern operating system. Note that Teredo might have been detected; but if it was, we found that it was not used for normal named web sites (only for raw IPv6 address connections).

IPv4 + IPv6

Rejoice!

624

6to4

Provision working IPv6 to the user; ensure the user has a modern home router and a modern operating system. 6to4 will be ignored when a useful IPv6 service is found.

IPv6 only.

This is expected in some lab and experimental setups only. Note that to reach this status, the IPv6-only user will have to connect to ipv6.test-ipv6.com (or similar mirror sites).
