Why doesn't systemd-resolved use my local DNS server?

I'm using a local BIND9 server to host some local dns records. When trying to dig for a local domain name I can't find it if I don't explicitly tell dig to use my local BIND9 server. user@heimdal:~$ dig +short heimdal.lan.se user@heimdal:~$ dig +short @192.168.1.7 heimdal.lan.se 192.168.1.2 Ubuntu 17.04 and systemd-resolved are used. This is the content of my /etc/resolved # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN # 127.0.0.53 is the systemd-resolved stub resolver. # run "systemd-resolve --status" to see details about the actual nameservers. nameserver 127.0.0.53 And the output from systemd-resolve --status Global DNS Servers: 192.168.1.7 192.168.1.1 DNSSEC NTA: 10.in-addr.arpa 16.172.in-addr.arpa 168.192.in-addr.arpa 17.172.in-addr.arpa 18.172.in-addr.arpa 19.172.in-addr.arpa 20.172.in-addr.arpa 21.172.in-addr.arpa 22.172.in-addr.arpa 23.172.in-addr.arpa 24.172.in-addr.arpa 25.172.in-addr.arpa 26.172.in-addr.arpa 27.172.in-addr.arpa 28.172.in-addr.arpa 29.172.in-addr.arpa 30.172.in-addr.arpa 31.172.in-addr.arpa corp d.f.ip6.arpa home internal intranet lan local private test The DNS Servers section does seem to have rightfully configured 192.168.1.7 as the main DNS server (my local BIND9 instance). I can't understand why it's not used ... ?
