After you have a site up and running, you need to give it an address that people can remember The Domain Name System (DNS) is sort of an address book of the entire Internet DNS is the mechanism by which you assign a name to your site

Before creating a domain name, you should understand the basics of how this system works: Every computer on the Internet has an IP (Internet Protocol) address When you connect to the Internet, a special number is assigned to your computer This IP address uniquely identifies your computer Client machines don t need to keep the same address For example, my notebook has one address at home and another at work The addresses are dynamically allocated A server needs a permanent address that doesn t change IP addresses are used to find computers Any time you request a Web page, you re looking for a computer with a particular IP address For example, the Google IP address is 661029104 Type it into your browser address bar, press Enter, and you see the Google main page DNS names simplify addressing IP numbers are too confusing for human users The Domain Name System (DNS) is a series of databases connecting Web site names with their associated IP numbers When you type http://wwwgooglecom, for example, the DNS system looks up the text wwwgooglecom and finds the computer with the associated IP You have to register a DNS name Of course, to ensure that a particular name is associated with a page, you need to register that relationship

purchase it immediately If a domain is available to transfer, it means that somebody else probably owns it Don t search for domains until you re ready to buy them Unscrupulous people on the Web look for domains that have been searched and then buy them immediately, hoping to sell them back to you at a higher price If you search for a domain name and then go back the next day to buy it, you often find that it s no longer available and must be transferred

The domain-purchase process involves registering yourself as the domain owner Figure 1-16 shows a typical form for this transaction WHOIS information provides your information to people inquiring about the domain name
