** Summary changed: - nslookup doesn't works + Slow DNS lookup through Netgear DG834G V4 router -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1609546 Title: Slow DNS lookup through Netgear DG834G V4 router Status in systemd package in Ubuntu: Triaged Bug description: On up to date Yakkety if I specify my Netgear router as the DNS server (via Network Manager) then DNS lookup takes about 30 seconds. I see the delay when I run, for example, systemd-resolve www.google.com or wget www.google.com I do not see the same delay if I run nslookup www.google.com A clue may be that in syslog I see Aug 3 21:20:56 dibbler systemd-resolved[2362]: Using degraded feature set (UDP+EDNS0+DO) for DNS server 127.0.1.1. Aug 3 21:21:16 dibbler systemd-resolved[2362]: Using degraded feature set (UDP+EDNS0) for DNS server 127.0.1.1. Aug 3 21:21:32 dibbler systemd-resolved[2362]: Using degraded feature set (UDP) for DNS server 127.0.1.1. I do not see the issue if I specify an external DNS server. I do not see the issue on 16.04, nor previous versions, or on other devices connected to the network. I have been using this router for years.
