DNS names are stored in domains. One condition, DNS, make-known names on the Internet, is to register the corresponding domain.
In principle, even without a participant in the Internet domain names to reach – the correct IP address is enough in most cases. The numeric IP addresses can be pinned but in general more difficult than descriptive names.
In addition, a domain also provides other advantages such as accessibility at the same address, even after changing servers, virtual host name and load balancing via DNS. Made available, or the servers on their own behalf is therefore essential for a successful web presence.
A simple and cheap way is to fill in an existing domain, as a sub-domain. Suppose the fictitious company example GmbH uses the domain of your service provider ISP. Then the name of the domain might look like this:www . beispiel-gmbh.isp . com. A registration is not necessary, since in principle (with some exceptions) only register domains that lie directly below a top-level domain.
Normally, however, separate names desired must be registered with a domain registration organization – a domain name registrar. This will firstly ensure that they comply with all formal rules and, secondly, as a guarantee that no one else uses this domain.
Registration Organisations
A Network Information Center is an organization that manages the domains. A domain name registrar acts as an interface between the Registry and the Registrant.
As a registrant, the customer is known, so anyone who wants to actually register a particular domain. For legal or other reasons, this designation may be nationally uncommon, in Germany we speak for example of the domain holders.
Connectivity
Domain registration alone is not sufficient to publish domain name on the Internet. First, each domain on one or more name servers in a zone file must exist. Then be in a zone that contains the parent domain to be a reference (delegation) added to this name server.
Connected to a domain registry entries are therefore always in the parent name servers. The NS resource records required to be borne by the Registrar together with the responsible Registry, a normally automatically in the parent server. In general, the registrar checks before registering this information in order to ensure that the delegation does not point into the void.
For smaller domains, which contain only very few resource records can be like (.Com) to dispense with a separate name servers for some top-or second-level domains. The resource records can then be directly deposited by the domain registrar on his own name servers.
Before you register, you will need to provide some clarifications
