What is a domain name?


A domain name is an identifier used on the Internet to locate a machine or group of machines on the network.

Machines on the Internet are identified with a unique number called an "IP address" (for example 194.69.254.2). IP addresses are not intuitive or simple to remember, so it is necessary to create an entity that helps remember a machine or group of machines providing services on the Internet (Web, mail, ftp…) more intuitively.

Why have a domain?

A Domain enables a person or company to be present on the Internet, making it possible to access them from any point in the network. The domain becomes the reference name of a given person or company on the Internet, and all the services the user needs can also be articulated from this domain (Web, mail, ftp…).

What are "Top level domains"?

A Top Level Domain (TLD) is the highest category level of a name on the Internet. In the Internet domain names system, the top level occupies the highest hierarchy rank offered on the network.

What types of "Top level domains" exist?

 

Two types of "Top level domains" exist: generic domains, with no territorial link, the best known being ".com", ".org", ".net", and ".edu".

Territorial or (ccTLD) domains are those corresponding to the territorial codes of each country (such as ".es", ".fr", ".uk", ".pt" …). These domains are managed by the assignment authority in each country that freely establishes the regulations for the assignment.

What is the difference between a ".com" and ".es" domain?

 

Domain names registered under ".com" and ".es" are second-level names; ".com" is a generic Top Level Domain; ".es" is also a top level domain but, rather than being generic it is territorial. The basic difference is with regard to the rules and assignment authority. Domains under ".com", like the other generic domains (".com", ".net", ".org", ".info" or ".biz"), are granted internationally by different registries, and there are very few assignment regulations.

Domains under ".es" are assigned by the Spanish assignment authority Red.es and it is essential for the applicant to be linked to Spain, with regulations to guarantee the security of the assignment, preventing the occupation of domains for speculative purposes, and therefore offering the user more security.
