Abstract:
   DNS Cookies, as specified in [RFC7873], are a lightweight DNS
   transaction security mechanism that provide limited protection to DNS
   servers and clients against a variety of denial-of-service and
   amplification, forgery, or cache poisoning attacks by off-path
   attackers.

   This document provides precise directions for creating Server Cookies
   so that an anycast server set including diverse implementations will
   interoperate with standard clients.

   This document updates [RFC7873] with

   *  suggestions for constructing Client Cookies in a privacy
      preserving fashion,

   *  precise instructions for constructing Server Cookies deprecating
      the methods described in [RFC7873], and

   *  suggestions on how to update a server secret.

   An IANA registry listing the methods and associated pseudo random
   function suitable for creating DNS Server cookies is created, with
   the method described in this document as the first and as of yet only
   entry.
