Public bug reported:

I have a little LAN (3 computers) where each computer uses UBUNTU 14.04 LTS. The LAN has a server that assigns the IP address by MAC ADDRESS and provides DNS resolution for local computers.
The BUG is for each computer of the network (I have not tested the server that is and ODROID and has not monitor and keyboard).
For example a computer is called "core". If I try to connect to "core I got the following message:

ssh -X core
ssh: Could not resolve hostname core: Name or service not known

and if I try lookup command I got

User:marco Computer:i7 Base:marco Current:/media/data/users/home/marco 
Command 1003 of 14 $nslookup gaia
Server:		127.0.1.1
Address:	127.0.1.1#53

** server can't find core: NXDOMAIN

After a random time (it can be few seconds or some minutes) the address
is resolved

$nslookup gaia
Server:		127.0.1.1
Address:	127.0.1.1#53

Name:	gaia.lab
Address: 10.10.100.11

and after the first resolution the address are resolved for all the
computers of the LAN. I have not problems to resolve the address outside
the LAN.

the reverse address is decoded:
nslookup 10.10.100.11
Server:		127.0.1.1
Address:	127.0.1.1#53

11.100.10.10.in-addr.arpa       name = gaia.lab.


The DNS servers are:
nameserver 10.10.100.7
nameserver 8.8.8.8
nameserver 8.8.4.4
/etc/resolvconf/resolv.conf.d/base (END)


where  10.10.100.7 is the server of the network.

Please contact me if I can provide you more information.
