Public bug reported:
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.
