The Domain Naming System (DNS) is a glorious thing. It takes familiar Internet network and machine names (like "amazon.com") and converts them to Internet Protocol (IP) addresses (like "208.35.218.15") that are meaningful to routers and therefore useful for identifying the machine you want to reach. What's amazing is that DNS enables someone in Germany to refer, by name, to a computer in Mongolia even if no one in Germany has ever accessed the distant machine before.
