   Title:   IP Fragmentation Avoidance in DNS

Abstract:

   The widely deployed EDNS0 feature in the DNS enables a DNS receiver
   to indicate its received UDP message size capacity which supports the
   sending of large UDP responses by a DNS server.  Large DNS/UDP
   responses are fragmented, and IP fragmentation has exposed weaknesses
   in application protocols.  It is possible to avoid IP fragmentation
   in DNS by limiting response size where possible, and signaling the
   need to upgrade from UDP to TCP transport where necessary.  This
   document specifies techniques to avoid IP fragmentation in DNS.
