Title: IP Fragmentation Avoidance in DNS over UDP

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
messages are more likely to be fragmented and IP fragmentation has
exposed weaknesses in application protocols. It is possible to avoid
IP fragmentation in DNS by limiting the 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.
