Abstract:
   EDNS0 enables a DNS server to send large responses using UDP and is
   widely deployed.  Path MTU discovery remains widely undeployed due to
   security issues, and IP fragmentation has exposed weaknesses in
   application protocols.  Currently, DNS is known to be the largest
   user of IP fragmentation.  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 proposes to avoid IP fragmentation in DNS.
