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.
