Web Hosting - DNS, How The Internet Keeps Track of Names The way computers communicate is, in a way, very similar to something very familiar: the postal system that delivers letters and packages. Here's how... The Internet is just what the name suggests, a large inter-connected set of networks. But those networks are pointless without the one part that forms what is called their 'end-nodes', otherwise known as computers. Those computers often need to share information because the people who use them want to share information. But, in a system where there are millions of separate computers, how can you enable them all to communicate? One very important feature of that solution is performed by something called DNS, the Domain Name System. Every part of a network that is going to send or receive information is assigned an IP address. That's a numeric identifier that uniquely specifies a particular 'node', such as a computer, a router that directs traffic or other component. They look like this: 209.131.36.158 But those numbers are more difficult for people to remember and work with. They also aren't very attractive from a marketing perspective. So, a naming system was layered on top of some of them, mostly the computers involved, though routers have names, too. But once you have a system that associates a unique IP address to a given name, you need some way of keeping track of all of them. That's carried out by several different pieces of the system: Name Registrars, DNS Servers and other components. The Name Registrars, overseen by IANA (Internet Assigned Numbers Authority) and other international bodies, provide and keep track of domain names. When you register with GoDaddy or any of a hundred other intermediate companies, ultimately that information makes its way into a number of specialized databases stored inside DNS Servers. A DNS Server is the hardware and/or software that tracks and forwards the IP Address/Domain Name pair from one place to the next. In many cases, there are a number of them between your browser and the remote computer you want to share information with. Suppose you request information from, say, Yahoo's site by clicking on a link on their site. DNS resolves (translates) the name of WHO IS making the request and OF WHOM, to addresses, then passes the request through the network to the requested IP address. The requested data is then passed back through the mesh of network components to your computer and displayed in your browser. Whether the communication is between a desktop computer and a server somewhere, or between one server and another, the process is essentially the same. DNS servers translate names into IP addresses and the requests for data are forwarded on. In some cases those DNS servers are part of a specialized network computer whose sole job is to do the translation and forwarding. In other cases the DNS software may reside on a server that also houses a database of general data, or stores email, or performs other functions. But however complicated the chain or the parts, the basic process is simple. Translate the name to an address, just as the postal system does. Whether international or local, your name is associated with an address, and the deliveries are made to the address, then forwarded to a particular name.

Yes, Freebies are Real! If you tell someone that something is free, they immediately start looking for the catch. After all, the words of wisdom “there is no such thing as a free lunch” have usually been proven true for people time and again throughout life, and so a healthy cynicism towards free stuff usually springs up with good reason. If you are one of these skeptical types, however, you may be missing out on some really great stuff. The truth is that you CAN get free things that are really and truly free, and yes, actually worth having. You just have to know where to look. OK, here is where the caveat comes in. The definition of “free” often depends on the definition of “cost.” As any economist can tell you, cost really doesn’t only come down to how much money you have to hand over to get something. There are additional costs, like inconvenience and time spent doing something. And true, some freebies have these “non monetary” kinds of costs associated with them. You have to balance all of the costs with the value of the free stuff you are getting and decide if it is worth it to you. The two biggest costs associated with freebies? Time and convenience are at the top of the list. Time is a big factor in many free offers. Companies want a bit of your time in exchange for their free products. Indeed, some companies literally want hours of your time. Have you ever taken advantage of one of those “free weekend vacation” offers in which you received free accommodation in a beach house or condo for a weekend in exchange for suffering through a long presentation and intense sales pitch? For some people, they can handle the presentation and have no qualms about refusing to buy anything and the free vacation more than makes up for it. Other people would rather pay any price to avoid having to listen to one of these spiels. So, while these weekends are freebies, for some people, they cost too much. More often, a company wants your time in a less obvious way – they want you to spend time filling out forms. These forms may simply be your name, address and email address, or they may be very lengthy, quizzing you about buying habits and the like. The reason the companies want you to do these forms is often for market research, and they are more than happy to give you a freebie in exchange for this. Many people find the time spent filling out these forms will worth it to get a great free product. Convenience is the other cost involved with many freebies. Time and convenience go hand in hand in some cases – after all, it may not be especially convenient to fill out form after form simply because it is time consuming, but convenience takes another hit from freebies in the form of spam email. Often, signing up for a freebie can land you on a spam email list, and for some people, getting tons of spam is so inconvenient that they would rather pay full price. The truth about all of these costs of freebies is that the freebie is in the eye of the beholder. You have to decide what you are willing to put up with in order to get a free product. Once you know the limits to your freebie costs, than you can cash in on some really great products that don’t cost you a dime. When you spend five minutes filling out a form and get rewarded with a free DVD player that you have been wanting, you will realize that there are free things out there to be had.
