I have done a bit of research on that matter, and the result is the 
following:

Assuming your system is using nsswitch (most current systems will), the 
name resolution methods and priority are defined in nsswitch.conf. The 
services and order are configurable.

The default on my OEL7.1 box is:

hosts:	files dns
# this would indeed look into /etc/hosts, and only look in dns if no 
entry is found in hosts file

Actually, that means that you need no entry but the pointers for lo in 
hosts, given you have an available dns.

Nothing would prevent you from reverting the lookup order to
hosts: dns files, either.
