It's more of a Java networking question that Tomcat question.  I'm not
sure how java's InetAddress class likes hosts files: my guess is they're
ignored.

Localhost is just the default name.  You can substitute any string in
there, and have as many Hosts as you want inside the Engine, but the
Host name must be unique within the Engine.

The name of the Host in server.xml is used primarily by Tomcat for
internal management.  It doesn't have that much to do with the host name
in the browser's URL.

That's not a Host configuration question.  It's a Connector
configuration issue.  What you would do is define an Engine with a
Connector that only listens on a specific IP address (that of the box
running Tomcat), and define your Host inside that Engine instead of the
default or open Engine.
