Domain

The name by which an IP address is identified to be easily used by internet users.

Types of domains

Top-Level Domains (TLDs) can be territorial (.es, .mx, .it) or generic (.com, .org, .edu). Second-Level Domains (SLDs or 2LDs) are the names that accompany TLDs, and they can also include details of the address (.com.es, .gob.es, .nom.es).

Using our own domain as an example, acrelianews.com is composed of the name "acrelianews" (SLD) and the extension ".com" (TLD).

In addition, there is a third level corresponding to a subdomain, generally "www," although it can also be a folder on the server (blog, mail). Together with the protocol (https), they form the URL of a web page.

How to register a domain

A website is a brand's home on the internet, so it's advisable to maintain its naming whenever possible. This will be the primary domain name. However, it is possible to choose others for more commercial purposes, including keywords for positioning or to purchase them for specific campaign microsites.

Generic domains can be purchased from any registrar, but for territorial domains, you need to go to an accredited one for the corresponding location. Keep in mind that each country may have its own rules for approving registration, such as being in the official language or the company having offices there.

To register a domain, the first step is to check its availability, i.e., make sure no one else is using it:

• If the domain is available, you can choose how long you want to buy the name, enter the details of the responsible person, and make the payment.
• If the domain is occupied because someone else registered it, you can find out the public details of who did it through pages like ICANN's.

It is possible to register a domain and park it or redirect it to another considered primary. This is a way to protect the use of the brand in other countries because the domain extension is a strategic decision. For example, choosing to have only the .com or creating as many pages as territories occupied depends on the presence in each location.
