Title: Fragmentation Avoidance in DNS

Abstract:
EDNS0 enables a DNS server to send large responses using UDP and is
widely deployed. 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 proposes techniques to
avoid IP fragmentation in DNS.
