The Internet protocol (IP) uses internet address information and the DNS to deliver the mail and other information from computer to computer.The following domains are common in the U.S: .com ( Commercial ); .edu ( education );.gov ( Government ); .mil ( Military ); .net ( Network-companies and groups concerned with the organization of the internet); and .org ( Organization ). Only two letters are used outside the US to identify the domains. For example .au for Australia; or .de for Deutschland. Because the numbers of internet sites has been growing exponentially, there are plans to expand the numbers of domains well beyond those that already exist.In the future, many new domains are expected to be available in addition to the existing .com, .edu, .gov, .mil, .net, .org. As an example of how the DNS works, here`s NASA`sSPACElink Internet address: spacelink.msfc.nasa.gov the top domain is .gov, which stands for government. The domain just below that is .nasa, which is the NASA domainThen below that, msfc ( Marshall Space Flight Center ) is one of NASA`s many computer networks. SPACElink identifies the NASA computer that runs the SPACElink program.SPACElink`s numeric IP address has changed through the years, but its Internet address has stayed the same.The DNS system keeps track of changes like the one just mentioned so that even when IP address changed, if the internet address is used , e-mail will always be delivered to the proper place. Computers called name servers are responsible for keeping track of such changes and translating them between IP addresses and domain addresses.
