Domains and subdomains: what they are and how they differ

Internet jargon includes some concepts which are very similar and can cause confusion when it comes to defining them. Two of these are domain and subdomain. What defines them and where do they come into the picture?

We are already familiar with the domain, which is the name we are known by online, a name which is easy to remember and easy to write, associated with a physical internet IP address where our page is housed. A subdomain is basically a domain which forms part of a larger one.

Contrary to what one might think, a subdomain is not a subsection of our domain. For instance, if the domain name is domain.barcelona, the subdomain would not be domain.barcelona/actualitat. That would be a page within a domain. A subdomain would be something like faqs.domain.barcelona.

A subdomain is a new independent website, but without the need to create another domain. It can have its own subsections and function on its own.

Why create a subdomain?

There are various advantages to creating a subdomain. The first is that different sections can be organised completely independently of the website content published on the main domain. This is the main purpose of a subdomain: to separate the different sections of a website and organise content more effectively.

Another reason is to avoid loading your main domain up with information. In practice it is another domain with its own images, extensions and pages. This makes browsing quicker.

Finally, another notable advantage is that you won’t have to pay for another domain. Many registration companies include unlimited subdomains in the price of the domain.

How do I create a subdomain?

First of all, you need to think about the name you want to give it. The shorter and more descriptive it is, the better. For instance, if it is to host an online store, it is best to call it shop.domain.barcelona, so users can see where they are straight away.

Creating a subdomain is not complicated. On the control panel offered by the registration company for your domain there should be a relatively simple option allowing you to create one. Either way, don’t hesitate to check with the technical department and enjoy the advantages of having a subdomain for your .barcelona.

How to transfer your .barcelona domain

The register is the central database where all domain names are stored. Access is only available to registration agents accredited by ICANN, a non-profit organisation working to guarantee a stable global internet, from where we must proceed with registration. We can find out through them whether the name we want is available before contracting the use of the domain for a certain period. At present we can register our .barcelona domain through various companies, which compete with each other on pricing, extra services and customer support. Here you can find a full list of accredited registration companies offering the .barcelona domain.

But what if we want to change the registration company without losing our domain? Is that possible? The answer is yes, we can freely transfer the domain name from one registration company to another. ICANN transfer policy is designed to increase domain registration options and foster competition between registration companies.

There is only one main requisite, and that is that 60 days must have elapsed since the date of registration of the last transfer. The expiry of the domain should also be taken into account. The change of registration takes between 5 and 10 days and so if the domain contract is about to expire we might not be in time.

There are four simple steps to transferring a domain name:

  1. Ask your current registration company to unblock the domain and provide the authorisation code.
  2. Give this to the new registration company.
  3. Confirm the transfer of the domain.
  4. Wait a few days until the process is completed.

During this process, and in the days following the change of registration, our .barcelona website should continue to function and there shouldn’t be any technical or bureaucratic issues for us. Both companies, the current provider and the new one, receive notification. This makes the process more transparent and reduces the possibility of fraudulent transfers.
