Thank you for the detailed explanation. Let me clarify some things here:
1) In the initial reply, I provided two types of reponses: - A successful one, that goes right through EDNS0 with UDP payload size 4096 - An unsuccessful one, that goes through the local stub resolver, but with udp payload size 512. I believe that successful example confirms that EDNS supports larger UDP payload size. Is it correct? Could you please advise how to increase UDP payload size for the local stub resolver? 2) I have gathered data using tcpdump, I hope it sheds some light on this. ** Attachment added: "dns.pcap" https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1886128/+attachment/5390841/+files/dns.pcap -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886128 Title: systemd-resolved does not resolve address due to udp payload size.
