By default, with LLMNR=yes set in /etc/systemd/resolved.conf, here are the port bindings (using netstat -l -p -a -n):

tcp        0      0 0.0.0.0:5355            0.0.0.0:*               LISTEN      8214/systemd-resolv
tcp6       0      0 :::5355                 :::*                    LISTEN      8214/systemd-resolv
udp        0      0 0.0.0.0:5355            0.0.0.0:*                           8214/systemd-resolv
udp6       0      0 :::5355                 :::*                                8214/systemd-resolv

When LLMNR=no is set in /etc/systemd/resolved.conf, I still have the following bindings:

udp        0      0 0.0.0.0:5355            0.0.0.0:*                           8214/systemd-resolv
udp6       0      0 :::5355                 :::*                                8214/systemd-resolv

How can I completly unbound all LLMNR port bindings?

System: Ubuntu server 15.04

After setting LLMNR=no in /etc/systemd/resolved.conf Have you tried restarting the systemd resolved service issuing the command below?

systemctl restart systemd-resolved.service
