Hello, Not a bug report so much as a query; why does dnsmasq not eagerly attempt to use EDNS when talking to upstream resolvers?
Quoting https://www.mail-archive.com/dnsmasq-discuss@lists.thekelleys.org.uk/msg10449.html : EDNS (in this context) is a way for the two ends of a DNS transaction to negotiate the maximum size of reply that can be sent over UDP. Quoting RFC6891: EDNS is a hop-by-hop extension to DNS. This means the use of EDNS is negotiated between each pair of hosts in a DNS resolution process, for instance, the stub resolver communicating with the recursive resolver or the recursive resolver communicating with an authoritative server. I was mildly surprised to find that dnsmasq will happily "pass through" EDNS, but won't try to use it otherwise if not flagged in the initial query. Cheers, Phil _______________________________________________ Dnsmasq-discuss mailing list Dnsmasq-discuss@lists.thekelleys.org.uk https://lists.thekelleys.org.uk/cgi-bin/mailman/listinfo/dnsmasq-discuss
