I think this file keeps a map of some hostnames/IP addresses, and
according with the configuration in host.conf the system could use it
to resolve names before asking an external source. My problem with
this is that I have a java application that needs to know the IP
address of the machine on which it is running. If the /etc/hosts file
contains just the line "127.0.0.1 localhost", my application gets an
error cause it can't resolve the machine's name. I can solve this
problem if I add a line with the machine's IP and its name but, as I
said, every time the IP changes I need to go there and put the new IP
in order for my application to properly run. That's why I want to
automatically update /etc/hosts.
