Title:
  systemd-resolved returns only short hostname when PTR record of local
  IP is requested

Status in systemd package in Ubuntu:
  New

Bug description:
  Ubuntu 17.10 comes with systemd-resolved as the default local
  resolver.

  When querying the PTR record of any local IP address it returns only
  the hostname (without domain) and does not forward the query to the
  available nameservers.

  This results in unwanted results.

  How do I change that behaviours without disabling and masking systemd-
  resolved and manually putting the nameservers in /etc/resolv.conf?

  Example:

  root at files05:~# host 192.168.48.115
  115.48.168.192.in-addr.arpa domain name pointer files05.
  root at files05:~# host 192.168.48.116
  116.48.168.192.in-addr.arpa domain name pointer files06.example.net.
  root at files05:~# host 192.168.48.120
  120.48.168.192.in-addr.arpa domain name pointer files05.
  root at files05:~# host 192.168.48.120 192.168.48.2
  Using domain server:
  Name: 192.168.48.2
  Address: 192.168.48.2#53
  Aliases: 

  120.48.168.192.in-addr.arpa domain name pointer fileserv.example.net.
