They are known as the "Big 3" for the reason that these domain name extensions are accessible to anyone, without restrictions, and are widely known throughout the cosmos. The second type of the top-level domain names are the Country-level top domains. It is noted that these types are generally under government control, with the purpose of adding level of toughness and stability that a third party might find tough to level. In taking into the domain name renewal, it is a common observation that a domain name registrant add whatever amount of time he or she select on the remaining time on his or her domain name registration. One of the examples that show this kind of situation involved in the domain name renewal is this one: if you have eleven months remaining on your domain name registration and then you decided to keep your domain name for a very long period of time, it is fact that you can perform a domain name renewal for nine years, but the maximum number of years is ten. The whois database maintained by the domain name registrars that list contact information about all the domain names issued by the registrar then serves as a major vehicle for knowing who owns domain names. And fortunately, this vehicle for determining who owns domain names is now available on the web and is open to be searched. In case if there are requests for domain names, such groups then communicate with the respective Registry to make certain whether the requested domain name is available for purchase or already owned by another party. So it is understandable that if the requested domain name is available, the consumer is able to register the domain. So as result, it is therefore important that the domain name must have matching IP address for it to function correctly. This is also one of the best explanations that show how the domain name and IP address are connected. This explanation alone led to the association between the two and thus being identified as a domain name IP address. With their domain name lookup service, they will automatically track the appropriate "whois" database server for a certain domain name, and then questions that database for details about that certain domain name. Also, they return all the available data after such process of locating the domain names.
