Title: IP Fragmentation Avoidance in DNS Authors: Kazunori Fujiwara Paul Vixie Name: draft-ietf-dnsop-avoid-fragmentation-16.txt Pages: 13 Dates: 2023-12-12 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.
