Description
This presentation measures the change in the behaviour of DNS recursive resolvers in response to DNS Flag Day 2020. The presentation then looks in more detail at the use of the EDNS(0) Buffer Size parameter and the considerations that guide the selection of a threshold for DNS truncation that will shift a DNS transaction to use TCP.
