What is a domain

What is a domain?

The domain is the name that identifies a website, and is composed of the web name + the domain extension.

For example, the domain of this website is, and there can not be a website that has the same domain. would be a different domain and could contain a totally different web to this one.

It’s like the phone number. Each person has their own and there can’t be two people with the same number.

Another thing to keep in mind is that the domain is not tied to the content of the web.

For example, if I go crazy and remove all the content from this website and next year I don’t renew the domain, someone else can buy it and install a website with erotic-festive content, SpongeBob or whatever, totally different from the content there is right now.

Again as the phone number. When you unsubscribe, it is assigned to a new client of the company. The number is still the same, but when someone calls it meets a totally different person than before.

You can buy it in many of the domain search engines or buy it at the same time you contract the hosting.

As I have already told you in the definition of domain, it consists of two parts: the name of the web and the extension of the domain.

The name of the web

It’s the name you want to identify your website with. The name of my website is “”.

You can choose the name you want to check that it is available in at least one of the domain extensions.

If you want it to be called “miweb”, you will have to search in a domain search engine like DonDomain if it is free.

Maybe the domain is busy (someone has already bought it and has a website set up), but the domain is free and you can buy it yourself.

In case it is not available for any of the main extensions (which we will see next) you would have to look for another name for your web.

Domain extension

The domain extension is what goes after the web name. In mine, the extension is “.com”.

There are many domain extensions, and more and more are coming out of new ones, but the best known and the extension par excellence is still “.com”.

And it is the first option you should take into account when buying your domain, because it works for any type of web, because it is the most remembered extension.

If the name you want to give to your website has the free .com extension, go get it and buy that one.

If it is not free, you have two options: choose another extension or look for another name that has the free .com.

After .com, the most popular extensions are .net, .org, .info and each country’s own extensions.

If you are in Spain and the public of your website will be exclusively in Spain, you can choose the .es extension.

The same if you are in Mexico with the extension .mx, or if you are in England with the extension .uk, and so on with all the extensions of each country.
