APNIC:IPv6, DNS, and truncation in UDP
https://blog.apnic.net/2024/03/14/ipv6-dns-and-truncation-in-udp/
In February I looked at the behaviour of the DNS when processing responses in UDP, which set the truncated flag in the DNS response. In particular, I was looking for the incidence of DNS resolvers that used the answer section in truncated responses (despite the admonition in DNS standards not to do so) and the extent to which there are DNS resolvers out there that are incapable of using DNS over TCP.
This month I’ll report on a repeat of this experiment using a test environment where only IPv6 can be used.
