Dear DNSOP WG, Paul Vixue and I submitted draft-ietf-dnsop-avoid-fragmentation-04.txt .
https://datatracker.ietf.org/doc/draft-ietf-dnsop-avoid-fragmentation/ https://tools.ietf.org/html/draft-ietf-dnsop-avoid-fragmentation-04 We changed to use "default maximum DNS/UDP payload size" instead of "default path MTU value". Please review current version and choose good "Default Maximum DNS/UDP payload size". Default maximum DNS/UDP payload size for IPv6 is XXXX. (Choose 1232, 1400, 1472 or other good values before/at WGLC) Default maximum DNS/UDP payload size for IPv4 is XXXX. (Choose 1232, 1400, 1452 or other good values before/at WGLC) Regards, -- Kazunori Fujiwara, JPRS <fujiw...@jprs.co.jp> > 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-04.txt > Pages : 11 > Date : 2021-02-22 > > 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.
