A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Domain Name System Operations WG of the IETF. Title : Fragmentation Avoidance in DNS Authors : Kazunori Fujiwara Paul Vixie Filename : draft-ietf-dnsop-avoid-fragmentation-07.txt Pages : 11 Date : 2022-07-03 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.
