One place to check is /etc/nsswitch.conf.

Look for the line starting with 
hosts: 

A working value is
hosts: files dns

This says when looking up host names, first check the
/etc/hosts file and then do a dns lookup.  If the dns
token is not present, ping and other utilities which
use the gethostbyname() call will not do a dns lookup.
