I've been struggling with this issue... It seems I have to append the localdomain to my local names for the resolution to work :
nslookup somename : SERVFAIL, 127.0.0.53 didn't proxy to my router nslookup somename.localdomain : OK, answer from my router Why somename request isn't forwarded to my router? Link 2 (eth0) Current Scopes: DNS LLMNR/IPv4 LLMNR/IPv6 LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no DNS Servers: 192.168.1.200 DNS Domain: localdomain I'm ok for some proxying to take place if that proves useful but so far it's only been a PITA for me so I disabled it following Vincent's answer. -- 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/1624320 Title: systemd-resolved appends 127.0.0.53 to resolv.conf alongside existing entries Status in systemd package in Ubuntu: Confirmed Bug description: systemd-resolved, or more precisely the hook script /lib/systemd/system/systemd-resolved.service.d/resolvconf.conf, causes resolvconf to add 127.0.0.53 to the set of nameservers in /etc/resolv.conf alongside the other nameservers. That makes no sense because systemd-resolved sets up 127.0.0.53 as a proxy for those other nameservers. The effect is similar to bug 1624071 but for applications doing their own DNS lookups. It breaks any DNSSEC validation that systemd-resolved tries to do; applications will failover to the other nameservers, bypassing validation failures. And it makes failing queries take twice as long. /etc/resolv.conf should have only 127.0.0.53 when systemd-resolved is active.
