I'm trying to understand what loopback interface is used for and /how/ it is works.
Anyone got any examples of how an app uses loopback interface effectively??
I vaguely know it acts like a remote node without actually being one. I'd like the details.

It is often used to provide daemons for your system to use, but that you don't want available publicly. A common example would be to have your SMTP server listen on localhost only. You could send emails through it, but no one else could. The SMTP server would still be able to send mail out to the Internet, it just wouldn't receive anything from the Internet.
