You're not sending any routed packets to 127.0.0.1. All you're
doing is sending a request to a DNS server that says, "Hey, what IP
address does the name www.redhat.org resolve to?"
Since the owner of "redhat.org" configured "www.redhat.org" to
resolve to the loopback address, you get a response to your DNS question
that says "www.redhat.org resolves to the following IP address:
127.0.0.1". Then, your web browser tries to connect to that IP.
If you're running a web server, you see the output.
No packets are ever "routed" to that IP address.
I own a domain... I might have one of the hostnames resolve to
192.168.0.1. That would have some very interesting results on certain
networks.
