Mr Ondrej Sury (CZ.NIC)


I would like to study and present the effect of parent (TLD) zone TTL changes based on behavior of different DNS resolvers implementations and how they handle the delegation NS TTLs. The presentation will include different scenarios where TTL matter, might matter, might not matter, or doesn't matter at all related to the DNS resolver implementations.
