Basically, because without a hosting and domain you can’t have a website on the Internet. Let’s see what each of them is for.


We’ll start with the domain, it’s a unique and easy-to-memorize name that identifies our website. The domain is bound by the Domain Name System (DNS) IPs where our website is stored or hosted. Without the help of the domain name system (created in 1980), Internet users would have to access each web service using the IP address of the node (for example, it would be necessary to use instead of http://google.com). In addition, it would reduce the number of possible websites, as it is currently common for the same IP address to be shared by multiple domains. The following example illustrates the difference between a URL(uniform resource locator) and a domain name:

  • Domain name: wikipedia.org
  • URL: https://www.wikipedia.org

Finally, it is not necessary to hire it together with the hosting, it can be purchased separately.

Structure and domain types.

The web domain consists of the name and an extension, which is used to identify what type it is. Internet domain types are divided into three large dominios groups, generic or gTLD (geopraphical Top Level Domain), ccTLD (country code Top Level Domain) territorial domains, and third-level domains. gTLDs are generic domains that do not conform to the environment of a specific country. The growth of the Internet has involved the creation of new gTLDdomains. As of May 2012, there are 22 gTLDs and 293 ccTLDs.

Generic domains or gTLDs.

gTLDs represent a number of names and multi-organizations worldwide. Initially, these domains were: COM, NET, ORG, EDU, GOB and MIL, which were subsequently joined by others.

  • .com – Trade. They are the most widespread domains in the world.
  • .biz – Business.
  • .org – Organizations.
  • .gov and .gob – Government and public entities.
  • .edu – Education.
  • .int – International entities and organizations.
Territorial domains or ccTLDs.

They are based on the two or three identification characters of each territory according to the abbreviations of ISO-3166 called ccTLD (country code top level domain). CcTLD-based domain names are managed by non-profit organizations in each country, delegated by IANA and or ICANN for the administration of territorial domains.

  • .es – Spain.
  • .pt – Portugal
  • .eu – Europe.
  • .eus – Basque Country.
  • .gal – Galicia.
  • .cat – Catalonia.
Third-level domains.

Third-level domains are those that serve the same purpose as gTLD domains only that they also acquire the territorial identity of ccTLDs. Government or educational domains are characteristic of this type. They simply have a .com.es, .edu.es, and so on.

New domains.

However outside of these three large groups, there are other types of domain extensions, some perhaps unknown and others more common than we think.

  • .app – Apps.
  • .coop – Cooperatives. It has a peculiarity and is that to register it it is necessary to prove the existence of the cooperative through the corresponding local body.
  • .info – Information.
  • .name – Own names or nicknames.
  • .pro – Professionals with university degrees.
  • .xxx – Sexual or pornographic content.


Hosting is the place where the files that make up our website are located. It is usually a small space on the hard drive of a server that is connected to the Internet 24/7 and the information stored on it can be accessible from any device with Internet access.

Types of servers.

  • Shared. It is the most common, in this case multiple applications or websites are hosted on the same server. It is the most affordable, the drawback is that sharing resources decreases the performance and speed of it, is less stable and safe than other alternatives.
  • VPS or Virtual Private Server. A virtual server consists of a virtual partition within a server with root access, which allows absolute control, as well as multiple websites and users. It is suitable for websites with mid-level traffic
  • Dedicated server. In this case the entire server is rented. It is ideal for high traffic websites.

Features of the hostings.

Your hiring is annual, although some providers facilitate monthly or quarterly payment. It is advisable to make sure that the supplier will provide us with quality service and good customer support in case of doubts.

Type of software or platform.

The first thing we will consider is the type of software of the server. Most hostings have LAMP services (Linux, Apache, MySQL and PHP). It is important to know what software and version our website will need.

Hard disk space or quota.

It is the number of gigabytes that we will have to store our data (mails, database, website files, images, downloadable files…).

Data transfer.

It’s the ability to exchange data. Each time you access our website a number of bytes are consumed. The heavier our website and the more visits we have, the more transfer we will need.


In some cases we find space limit and in other cases limit databases that we can create.

Email accounts.

Depending on the type of hosting we hire we will have more or less email accounts each of them with a maximum capacity, usually expressed in gigabytes.

FTP accounts.

Finally, FTP accounts allow you to access your directory within the server 24 hours a day. This way you can create and maintain your websites,images and scripts locally (on your computer) and transfer them to your space via FTP. They are used to give access to the server to different users without being able to access your account details. You’ll even have the ability to set a maximum disk usage space per account, i.e. you can restrict the use of FTP account web space.

Possible problems that may arise.

  • Slow server or problematic.
  • Hosting is located in another country and our website does not position correctly.
  • Web hosting does not have the necessary resources to host your website.
  • Poor security in web hosting.
  • Slow loading speed.
  • The hosting company does not have a technical support that is really helpful.
