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 amplification denial of
   service, forgery, or cache poisoning attacks by off-path attackers.

   This document updates [RFC7873] with precise directions for creating
   Server Cookies so that an anycast server set including diverse
   implementations will interoperate with standard clients, suggestions
   for constructing Client Cookies in a privacy preserving fashion, 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.
