.it domains are active after 3/4 days of the day on which the Italian Registration Authority receives the Letter of Assumption of Responsibility, whereas .com/.net/.org domains are active in 1/2 days of the online registration.
To use your domain you must wait until its settings are spread to the web. Register.it will send you an "activation confirmation" email. We remind you that in order to use the additional services you must have set up Register.it DNS.
In computing and telecommunication in general, a domain is a sphere of knowledge identified by a name. Typically, the knowledge is a collection of facts about some program entities or a number of network points or addresses.
On the Internet, a domain consists of a set of network addresses. This domain is organized in levels. The top level identifies geographic or purpose commonality (for example, the nation that the domain covers or a category such as "commercial"). The second level identifies a unique place within the top level domain and is, in fact, equivalent to a unique address on the Internet (an IP address). Lower levels of domain may also be used.
Strictly speaking, in the Internet's domain name system (DNS), a domain is a name with which name server records are associated that describe subdomains or host. For example, "whatis.com" could be a domain with records for "www.whatis.com" and "www1.whatis.com," and so forth.
In Windows NT and Windows 2000, a domain is a set of network resources (applications, printers, and so forth) for a group of users. The user need only to log in to the domain to gain access to the resources, which may be located on a number of different servers in the network.
Domain registration is the process by which a company or individual can secure a website domain, such as www.yoursite.com. Once you have completed domain registration the domain becomes yours for the period of the contract, usually one year. Before registration expires it must be renewed, or the domain reverts back to being available to the general public.
Domain registration is available to the public via a registrar. Fees and services vary from company to company, but the process is generally inexpensive. Before a domain registration can be approved, the new name must be checked against existing names in the DNS database. The online registrar provides a field into which you can enter your desired name and hierarchy —- that is, the letters that come after the "dot." Familiar hierarchies are .com, .net, .org, .name, .info and .biz. If the name is not already taken, it is available for domain registration.
During the domain registration process, you will be required to give contact information that will be publicly available through the WHOIS database. Anyone can go to a WHOIS search engine and enter a domain name to see who has registered it. Registrars require that this information be accurate and true. If you feel uncomfortable providing personal information, there are some registrars that will act as your proxy, supplying their information in place of your own as the contact for the domain. There may be a small fee for this service and potential drawbacks to balance against the ability to maintain your privacy, so read the Terms and Conditions carefully before deciding to opt for a domain by proxy.
Upon completing the domain registration process, it will take a period of hours to a few days to be able to see the domain online. The domain can be "parked" with an "in construction" page that acts as a kind of placeholder. Parking a domain is very inexpensive and most registrars offer this service for a small fee to give you time to come up with content. Once a registrant is ready to supply content, a web server must host the domain. The registrar might also provide hosting services, or you may wish to transfer your domain to anothr web hosting company.
You should renew a domain name registration at least 10 days before the expiration date. If the expiration date contains only a month and no day, then the expiration date is the last day of that month. If you do not renew your domain name registration on time, the name will be automatically removed. It is notify via email when your domain name registration is due for renewal.
