So today, many domain name registrars have told the domain name holders to pay the renewal or registration fees for the reason that they have only a few days left to hand over the cash. And the concept of domain name auction came out when the money is not forthcoming. With this domain name auction, thousands of people are expected to come under the hammer. Speaking of the "top-level domain name", it is very nice to know that some of the common top-level domain names used in the internet comprise the .gov which stands for government agency, .org for an organization, .edu for education institution, and .net for a network. Many domain name experts have considered that one of the best and simple trick for locating companies and organizations on the internet is definitely to enter the name with the appropriate top-level domain name. In terms of a country by country basis, the common domain name extensions are based on the two-character ISO country codes and this is for the main reason that many countries offered these kinds of domain name extensions. Among such kind of domain name extensions is the .fr for France, .jp for Japan, and so on and so forth. 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. It is just important to note some things about it since it is a common necessity for the domain name holders to change their registered domain name information. According to some experts, when you register a domain name, you really need to specify your Domain Name Server or DNS information. However, there are some instances that you need to change such registered DNS information for certain purposes. It is interesting to know that the consumers may not register a domain name directly from the Registry, they must do so by the domain name registrars. The Registries just charge the domain name registrars for registration. And along with such responsibility, the domain name registrars as well update the domain name at the corresponding Registry whenever a contact or DNS change is created.
