A domain name is like the address of your website, like an identifier. It allows users and new customers to search not only your website, but also your professional email address and any other services you might associate with it. It is also the basis of the URL for links leading to your website.

Technically, a domain name links a human-readable name (your domain name) to a computer-readable address (a series of numbers known as an IP address).

A domain name is generally composed of 2 parts, for example in "gandi.net":

"gandi" corresponds to the domain name registered with a registrar, it is the basis of your online presence. This domain name, once completed with a web hosting, can become your website. It can be the name of your brand or a keyword related to your activity.

".net" is the top level domain extension of your domain name, it completes your identity and contributes to your online visibility. Indeed, the choice of the extension of a domain name is more important than it seems. Your online presence is measured by the referencing of your website on search engines, it will be impacted by your extension, it must therefore be adapted to your target to appear in its search results. For example, if you are targeting a particular country, it makes sense to choose the domain name extension related to that country. Choosing the right extension can greatly contribute to the visibility of your domain name and therefore of your website.

Then the protocol and the DNS system allows you to link your domain name to an IP address. DNS is a kind of global directory of correspondence between domain names and IP addresses.

In some cases, your domain name may have subdomains, they correspond to sites called annexes but nevertheless linked to your main domain name. "News.gandi.net" is for example a subdomain of gandi.net.

You need to choose a name and a TLD or top-level domain extension. The domain extension is listed in the domain name system. There are hundreds of TLDs, but .com, .org, and .net are the most widely used ones.

The best way to choose a domain name is to pick one that meets all four of these criteria:

• Meaningful
• Easy to remember
• No strange spelling or grammatical irregularities
• Descriptive

The best way to approach choosing a domain name is to think about how you will use it. You will probably share it on social networks, announce it verbally to your friends and family, maybe print it on business cards, or post it on billboards. At the same time, people will probably find you through search engines. Check the availability of your perfect domain with our domains suggestion tools or check who owns it with our Whois service.

The first thing you need to do when you start creating a website or online store is to choose a domain name, do a search on your domain name availability, and register it. How do domain names work? Every domain name is registered or "bought" for a period of 1 to 10 years from a domain registries, which manages domain endings (.net, .fr, .com, .org, etc.).

Check to see if the right domain is available for your business online using our domain name search tool. You'll immediately see a confirmation screen that shows the domain availability. If it is available, you can add it directly to your shopping cart and buy your domain name!

Here is, generally, how domain registration works. Registries manage and sell domain names under the domain endings (.net, .fr; .com, .org, etc.) they are responsible for. Domain name registrars, like Gandi, are accredited by these registries to sell multiple domain names with each of these domain endings to end users (individuals, small businesses, large companies, associations, non profit organization etc.). An end user, then, will buy a domain name from a registrar, where they can do a domain name search of every domain ending. Once registered, a domain name is associated with an Owner Contact, who becomes the owner of the domain name for a specific period of time. If a domain name appears as "unavailable" in our search results, that's because it's already registered to someone else. You can check who owns it using our Whois serviceor look for alternatives using our domain name search tool.

So you want to create a website, but the web address you wanted is already taken and you don't want to "fall back" on another domain ending or use a different name. You have a few options, including finding the owner thanks to the Whois and offering to buy the domain name from them. The Whois is a directory that lists the technical and contact information of domain names, created when a domain name is registered with a registrar, such as Gandi. The whois contains information about the registrar, the domain registration and expiration date, and especially the update date, which is the last modification made to the domain name. This is a good indicator to tell you whether the domain name is active or dormant. Then you can try to contact the owner. The whois is not always the solution, though, since it isn't always kept up to date (if a contact changes, for example), but especially because GDPR (General Data Protection Regulation) prevents registrars from publishing the contact details of an owner (if not a company) without their consent. As a last resort, you can try to contact the owner through the contact page most websites have.

A domain name is an essential element to any website. To host a website, you should be sure to buy a domain name so that your website has an address. You'll also need to buy website hosting services for your website. We offer different hosting plans that each correspond to different levels of use. When you have your hosting plan, that will give you access to the FTP server, which requires an address (000000@sftp.dc0.gpaas.net), user (username), and password, where you can upload your site's files.
