And for everybody to comprehend the real nature of domain name registrars and the nature of their work and their role in domain name registration, one must then learn about the ICANN or the International Corporation for Assigned Names and Numbers. So speaking of the ICANN that plays a major part in the domain name registrars, it is necessary to know that it has two main responsibilities. And in conducting the registrar domain name transfer, a registrant or the administrative contact should then perform the request through the new registrar company. After which, a holder or the administrative contact must reply to the old registrar companies via e-mail which asks for authentication of the registrar domain name transfer. Perhaps, it is for the reason that many people these days, especially those who wanted to look for available domain names on the web, are really into some of the available and offered domain name lookup services. Given such truth behind the world of the domain names, I have presented a few of the available sites on the web today that provide domain name lookup services for the domain name lovers. This certain status of the domain name takes place when the domain name holder forgot to renew the registered domain name, and so when a certain domain name is given as "expired domain name", it is understandable that such expired domain name is on the way to deletion from the domain name registry. Given such fact, it is then a nice move if you have certain desire to sell a domain name that prior to getting down to the hard work that is necessary to sell a domain name, you know how to place some sorts of value on your domain name. In fact, even if you are not going to post or publicize the set value of the domain name, it is still significant that you are aware of the minimum amount that you would accept for it when you sell a domain name. As such, your contact, billing, administrative contact, and also your domain name server or DNS is added to this database. It is for the main reason that when someone lookup for a website, you are basically accessing this large database for all of the domain names entered through a domain name registration, and such database directs you to the necessary DNS to access their database to locate which computer your website is on.
