Abstract

   When a DNS server filters a query, the response to such query conveys
   no detailed explanation that elaborates why that query was blocked,
   leading thus to end-user confusion.  A solution to this problem is
   needed in order to enhance the user experience.

   This document defines a method to return an URI that explains the
   reason why a DNS query was filtered by a DNS server.
