Dear dnsop WG, Please review draft-fujiwara-dnsop-avoid-fragmentation-01. https://tools.ietf.org/html/draft-fujiwara-dnsop-avoid-fragmentation-01 Main differences are: - New Co-author - Refer RFC 8085 UDP Usage Guidelines - SHOULD send DNS responses with IP_DONTFRAG / IPV6_DONTFRAG [RFC3542] - Use actual path MTU information, or the default maximum DNS/UDP payload size - Added text about how to retrieve path MTU value in appendix getsockopt() IP_MTU and IPV6_MTU (Linux only) - default maximum DNS/UDP payload size >= 1220, and <= 1400 - Request to zone operator: Use smaller contents (number of RRs, DNSSEC key) -- Kazunori Fujiwara, JPRS <fujiwara@jprs.co.jp>
