What is a Top-Level Domain?
In the system of domain names, top level domain (in English top-level domain, TLD Short) is an area that is at the top of the hierarchy of domains.
In a domain name, the top-level domain is indicated by the label following the last point in the domain name (example: en.wikipedia.org in the top-level domain is org).
The list of top-level domains of the Internet to nearly 300 top-level domains. This includes:
* A top-level domain special
* Approximately 20 top-level domains generic;
* About 260 top level domains nationals.
Each top-level domain is managed by an organization that is responsible to allocate (possibly in a trade) its sub-domains.
The areas are divided into generic: Generic non-commissioned and commissioned domains. Broadly speaking, a generic non-sponsored special rules established by the entire Internet community represented by ICANN as a sponsored generic domain obeys the rules established by a sponsor representing the narrow uses the area.
Generic domains non-sponsored areas are divided into generic non-commissioned non-restricted areas and generic non-sponsored limited. The non-restricted areas are open to all, regardless of their areas, while non-generic domains are sponsored limited to organizations or individuals with specific characteristics (as well as areas sponsored). Contrary to the sponsored areas, applications for sub-domains in non-generic domains sponsored restricted are not subject to validation before the award of the subdomain name.
Sponsored generic domains are strictly managed by a sponsor. The sponsor, who received his authority from ICANN, a lot of latitude in setting the rules and in the management area that is assigned. One of the functions of the sponsor is to ensure that the applicant for a sub-domain has the characteristics that are displayed by the domain name. Thus the Sponsor field. Museum ensures that an applicant is a museum, a museum or a member of the museum profession.
TLD generic
A top-level domain generic (English generic Top-Level Domain or gTLD) is a top-level domain intended to sub-domains with a common characteristic other than geography. For example, .com is destined for sub-areas of commercial (at least it was at the origin, and today this area is open to all) and. Mil is intended to sub – domains such as military.
The areas are divided into generic Generic non-commissioned and commissioned domains.
Generic domains non-sponsored areas are divided into generic non-commissioned non-restricted areas and generic non-sponsored limited. The non-restricted areas are open to all irrespective of their areas while the non-generic domains are sponsored limited to organizations or individuals with specific characteristics (as well as areas sponsored). Contrary to the sponsored areas, applications for sub-domains in non-generic domains sponsored restricted are not subject to validation before the award of the subdomain name.
