What a domain name is, how it works, which extension to choose, what it costs and how to register or transfer it without mistakes.

You are launching a website, an online store or simply an email address in your own name, and the first question comes before the first line of code: which address should you take? Behind that choice sit very practical questions. Who really owns the address, how much it costs each year, which extension inspires trust, and what to do the day you want to change provider? This article answers them in order, with official rules and observed prices.
In short
- A domain name is the readable address of your website and email (for example your-brand.com): it replaces the server's IP address, which nobody remembers.
- You do not buy it, you rent it for 1 to 10 years, renewable, from a registrar that records it in the extension's registry (Afnic naming charter).
- The .fr extension is reserved for residents and companies in the European Union, Switzerland, Norway, Iceland and Liechtenstein; .com is open to everyone.
- A good name is short, easy to say, without unnecessary hyphens, and checked against trademarks before registration.
- A domain name can be transferred between providers with an authorisation code, but not within 60 days of its registration (ICANN).

What is a domain name, in practice?
A domain name is the text address that lets people reach a website or mailbox on the Internet without knowing the server's IP address. It combines a freely chosen name and an extension, separated by a dot: in "your-brand.com", "your-brand" is the name and ".com" the extension.
What a domain name lets you do:
- Publish a website at a stable address, even if you change host.
- Create email addresses in your own name, such as contact@your-brand.com.
- Redirect several addresses to one site, or an old name to a new one.
- Protect your brand by stopping a third party from registering the obvious address.
- Create subdomains (shop.your-brand.com, api.your-brand.com) at no extra cost.
The number of registered domain names worldwide passed 401.6 million at the end of the second quarter of 2026, according to Verisign's Domain Name Industry Brief. Short, obvious addresses are therefore often taken, which is why the choice deserves a method.
How does a domain name work?
Three players share the work: the registry runs the extension, the registrar rents you the name, and DNS translates the name into a server address. Your only contract is with the registrar.
| Player | Role | Example |
|---|---|---|
| Registry | Keeps the official database of an extension and sets its rules | Afnic for .fr, Verisign for .com |
| Registrar | Rents you the name, renews it and manages its DNS zone | Your domain provider |
| Registrant | The person or company in whose name the domain is registered | You |
| DNS servers | Answer the question "which IP address for this name?" | The name servers declared for your domain |
When someone types your address, their browser queries DNS, which returns your site's server IP. The main records to know:
- A / AAAA: the web server's IPv4 / IPv6 address.
- CNAME: an alias pointing to another name.
- MX: the servers that receive your email.
- TXT: verification and email authentication data (SPF, DKIM, DMARC).
- NS: the authoritative name servers for your domain.
You edit these records in the Wayhost domain and DNS management interface, without touching the server itself.
Which extension should you choose: .com, .fr or another?
For an international ambition, .com remains the reference; for a business focused on France, .fr is the clearest choice. Ideally, when budget allows, register both and redirect one to the other.
| Extension | For whom | Conditions | Watch out for |
|---|---|---|---|
| .fr | Companies and individuals targeting France | Residence or registered office in the EU, Switzerland, Norway, Iceland or Liechtenstein | Strong local signal for a French audience |
| .com | International business or global brand | Open to all | Short names are rarely available |
| .net / .org | Technical projects, non-profits | Open to all | Less memorable than .com |
| .eu | European business | Residence or office in the EU or EEA | Less widely used |
| .ai, .io, .cloud | Start-ups, tech, AI | Varies by registry | Noticeably higher prices |
The .fr extension remains very dynamic: Afnic counted 4.32 million .fr names at 31 December 2025, with a record 853,000 creations over the year (Afnic 2025 .fr review).
💡 Pro tip Do not pick an exotic extension to get around a .com or .fr that is already taken. Your customers will type the extension they know, and part of your email and traffic will go to whoever holds the obvious address.
How do you choose a good domain name?
A good domain name can be said out loud without spelling it, typed without errors, and creates no trademark conflict. Everything else is secondary.
Criteria to check, in this order:
- Short: under 15 characters where possible, the technical limit being 63 characters (Afnic naming charter).
- Easy to say: the phone test, dictating the name to someone who must type it right first time.
- No hyphens or ambiguous numbers: "2" or "two", "my-site" or "mysite"?
- No accents in the main address: many keyboards and email clients handle them poorly.
- Consistent with the brand: ideally the exact trading name.
- Free of rights: a search in trademark databases (EUIPO, national offices) before registering avoids a dispute.
- Durable: avoid a year, a city or a product that might change.
Syntax rules are simple: letters, numbers and hyphens, with no hyphen at the start or end of the name (Afnic).
How much does a domain name cost?
A standard domain name costs from a few euros to around fifteen euros a year; the real issue is the renewal price, not the first-year price. Many offers show a teaser price for the first year, then the full rate afterwards.
Prices observed on the Wayhost domains page on 5 October 2026 (excl. VAT per year, non-contractual):
| Extension | First year | Renewal |
|---|---|---|
| .fr | €7.70 | €7.78 |
| .com | €11.33 | €11.33 |
| .net | €13.09 | €13.09 |
| .org | €9.90 | €13.20 |
| .ai | €80.63 | €80.63 |
What should be included at no extra cost in the annual price:
- Full DNS management (A, MX, CNAME, TXT).
- Whois privacy protection for individuals.
- Web and email redirects.
- Automatic renewal, so you never lose the address by oversight.
At Wayhost, all four are included, as well as DNSSEC, according to the domain name page consulted on 5 October 2026.
How do you register a domain name, step by step?
Registration takes minutes: check availability, enter the registrant, pay, and the domain is live. What matters most is getting the registrant right.
- Check availability of the name in a domain search tool.
- Choose the extension and the term (1 to 10 years for .fr).
- Enter the registrant: the company or person who must remain owner, not the agency building the site.
- Turn on automatic renewal and check the contact email address.
- Configure DNS: point the domain to the site's hosting and to the mail servers.
- Create the email addresses tied to the domain.
Once the domain is live, all that remains is to connect it to your services: web hosting for the site and professional email for addresses in your name.
💡 Pro tip Always register the domain in the company's name, with a generic email address you control (admin@, domains@). A domain registered in the name of a former employee or an agency that has moved on is one of the most painful situations to untangle.
What does Whois contain and how do you protect your data?
Whois is the public directory showing who holds a domain name and with which registrar. It is used to contact a registrant, check an expiry date or prepare a transfer.
What you usually find there:
- The registrar and name servers.
- The dates of creation, last update and expiry.
- The domain status (locked, in transfer, expired).
- The registrant's contact details, hidden for individuals when privacy protection is on.
For an individual, these details can attract spam and phishing attempts. Whois protection hides them: at Wayhost, it is included free according to the domains page. For a company, transparency is instead a sign of credibility.
How do you transfer a domain name to another registrar?
Ask the old provider for the authorisation code, start the transfer with the new one, and the domain changes manager without downtime if it is well prepared. The registrant stays the same.
ICANN rules for generic extensions (.com, .net, .org):
- The authorisation code (AuthInfo) must be provided by the old registrar within 5 calendar days of the request (ICANN).
- No transfer within 60 days of the initial registration.
- No transfer within 60 days of a change to the registrant's name, organisation or email.
- The registrar may refuse a transfer within 60 days of the previous one.
Before starting, check that the domain does not expire in the coming days, that the registrant's email address works, and note the current DNS configuration. Wayhost has a dedicated domain transfer page, with one year of renewal included at transfer according to its domains page.
Which mistakes should you avoid with a domain name?
The costliest is letting the domain expire: the site and email stop, and the address can be picked up by someone else.
The mistakes we see most often:
- Domain registered in the provider's name rather than the company's.
- Automatic renewal turned off, or an expired payment card.
- Outdated contact email: expiry alerts no longer arrive.
- MX records forgotten when changing host, and email stops arriving.
- Unprotected variants: the .com taken, the .fr left to a competitor.
- Name chosen without a trademark check, with a risk of dispute and losing the domain.
An agency managing dozens of client domains should centralise these checks; our guide on VPS hosting for web agencies details how to organise it. And if your domain needs to expose an API or application, DNS setup is part of the go-live described in our article on hosting an AI application.
Frequently asked questions
What is a domain name in simple terms?
It is the address of your website and email on the Internet, such as your-brand.com. It replaces the server's IP address, a string of numbers nobody remembers. You rent it yearly from a registrar.
Can you buy a domain name permanently?
No, a domain name is rented for a limited period, then renewed. For .fr, the term ranges from 1 to 10 years under Afnic's charter. As long as you renew, nobody can take it from you.
How long does it take for a domain name to become active?
Registration itself is usually immediate after payment. DNS settings can then take from a few minutes to a few hours to propagate to all servers. During that time, some visitors already see the new site and others do not yet.
Should you take both .com and your local extension?
For a business targeting one country, the local extension often works well as the main address. Also registering .com protects the brand and catches visitors who type it by reflex. The second domain simply redirects to the first.
Who owns a domain name?
The registrant declared at registration, an individual or a company. The registrar only manages the domain on their behalf. Check in Whois or your customer account that the registrant really is your company.
Can you change domain name without losing your search rankings?
Yes, provided you set up 301 redirects from each old page to its new one. Keep the old domain active and renewed for several years, while search engines and your contacts switch over. Losses mostly come from pages forgotten in the redirect plan.
What happens if you forget to renew your domain name?
The site and email stop working as soon as the domain expires. A grace period usually lets you recover it, sometimes with restoration fees. After that, the name becomes free again and anyone can register it.
Does a domain name help search rankings?
A clear domain name mainly improves trust and click-through rate. Site content, speed and links weigh far more than a keyword in the address. A memorable brand name beats a string of keywords.
Key takeaways
- A domain name is rented, not bought: automatic renewal is your best insurance.
- The registrant must be your company, never your provider.
- .com for international, your local extension for home, and both when possible.
- Compare renewal prices, not just the first year.
- Prepare any transfer: authorisation code, 60-day windows, DNS noted before you move.
Found your address? You can check its availability and register it in minutes on the Wayhost domain name page, with DNS management, DNSSEC and Whois privacy included.
