It means you don't need to tell your browser, ftp client, or whatever that it
needs to use eth0. It knows it needs to follow a certain path and the tcp/ip
stack handles that. I would need to look at it ini more contextext in order to
say for certain that this is what the ¶aragraph means but this is my guess.
