Incorrect Working IPv6 Clients/Networks on the Internet

What’s the error rate of IPv6 networks and clients? And how can you measure it? One way to test it passively is to analyze returning ICMPv6 messages to your own servers that are public on the Internet such as NTP servers listed in the NTP Pool project.

Those NTP servers are polled regularly by many different systems such as clients, servers, IoT & infrastructure devices, and so on. This talk is about a case study looking at IPv6 error rates on the Internet, listing failure types and giving suggestions on how to correct them. Those approaches can be used on internal IPv6 networks as well, helping local IT network administrators decreasing IPv6 failure rates.
