Public bug reported:
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@files05:~# host 192.168.48.115
115.48.168.192.in-addr.arpa domain name pointer files05.
root@files05:~# host 192.168.48.116
116.48.168.192.in-addr.arpa domain name pointer files06.example.net.
root@files05:~# host 192.168.48.120
120.48.168.192.in-addr.arpa domain name pointer files05.
root@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.
