Your domain name
At Theory7 you can easily host your own domain name. We offer more than 1500 domain name extensions at the sharpest prices. With your own domain name you claim your unique spot on the internet.
Your domain name comes with all the features you need to go any direction you like. You can create your own email address (for example info@yourdomain.nl) and it is the starting point for your website or webshop. To run a website or webshop you also need a hosting package.
Already have an existing website on another domain name? Then you can quickly and easily link your own domain name to your existing domain with a 301 redirect.
A domain name is the unique address that visitors use to find your website, comparable to a postal address. The registration and management of domain names is coordinated worldwide by ICANN. In the Netherlands, SIDN is responsible for all .nl domains. At Theory7, as an official SIDN registrar, you register your domain directly, without any middleman.

Tips for choosing the perfect domain name
Short and powerful
Choose a domain name that's easy to remember and type. Keep it short and avoid complex spellings or special characters in your domain names.
Memorable domain name
Make sure your domain name contains your brand name or closely matches it to strengthen your brand identity and avoid confusion.
SEO-friendly domain
Consider including relevant keywords in your domain name to be found more easily in search engines like Google, but don't force it at the expense of brand recognition. If, for example, you run a shop that sells peanut butter, it can be smart to include the word peanut butter in your domain name.
To add to your domain name
How does the Domain Name System (DNS) work?
The Domain Name System translates readable domain names such as theory7.net into IP addresses that computers use to find each other. When you type in a domain name, your browser sends a request to a DNS server that looks up the corresponding IP address. This process takes milliseconds and is invisible to the user. The technical standard behind DNS is defined in RFC 1035 from the IETF.
At Theory7 you manage your DNS records via a clear control panel. You can set up A records, CNAME records, MX records for email and TXT records for verification yourself. Changes are applied to our own DNS infrastructure with servers in the Netherlands, so propagation is fast.
Choosing the right extension: .nl, .com or something else?
The choice between a .nl and .com extension depends on your audience. A .nl domain builds trust with Dutch visitors and scores better in local search results. According to SIDN, there are more than 6 million .nl domains registered, making it one of the most popular country extensions in the world.
A .com domain is the best choice for international visibility or if your .nl variant is already taken. For Belgian companies, .be is a logical option. At Theory7 you register .nl from EUR 0.45/yr, .be from EUR 0.85/yr and .com from EUR 8.95/yr. You can combine multiple extensions and redirect them to your main domain via free redirects with SSL.

The start of your online identity
What is a domain name and why does it matter?
A domain name is the address of your website on the internet. It makes it easy for visitors to find you online without any technical hassle. A good domain name is recognisable, professional and strengthens your brand.
Every domain name consists of a name and an extension such as .nl, .com or .net. You choose the name yourself – this could be your company name or a clever keyword. The extension sets the context: business, local, creative or international.
What if you already have a domain?
Registering vs. transferring: here's the difference
Want a new domain name? Then you register it — as long as it's still available. With our domain checker you can see that straight away.
Already have a domain elsewhere and want everything under one roof? Then you can transfer it. Here's how it works:
- You manage multiple domains across different providers and want to centralize everything.
- You're taking over a domain name from someone else.
More than just a name
Why a good domain name makes all the difference
A strong domain name is often the first thing someone sees of your brand. It determines not only your online visibility, but also your credibility. Short, catchy and relevant domain names stick better and drive more traffic to your website.
Choosing a domain name is therefore much more than a technical step – it's a strategic decision that affects how you're found and remembered.
- A unique domain name strengthens your brand identity and prevents confusion with others.
- The right extension can build trust, for example .nl for Dutch companies.
Frequently asked questions about domain names
What is the difference between a domain name and web hosting?
A domain name is your unique address on the internet (such as yourcompany.nl), while web hosting is the server space where your website is physically stored. You need both: a domain name so people can find you, and web hosting to put your website online. At Theory7 you can get both a domain name and a web hosting package.
How long does it take before my domain is active?
After you've registered a domain name, it's usually active in our systems within a few minutes to an hour. Global propagation via DNS servers can take up to 24-48 hours, but in practice your domain is often reachable much sooner. If you have questions about activating your domain name, we're here for you every day via the chat.
Can I link multiple domain names to one website?
Yes, that's possible. You can redirect different domain names to your main domain name. For example: if you own both yourcompany.com and yourcompany.nl, you can automatically forward visitors of yourcompany.com to yourcompany.nl. At Theory7 we offer free redirects with SSL on every domain name, so the safety of your visitors is guaranteed even with redirects.
What should I do if the domain name I want is already taken?
If your desired domain name is already registered, you have several options: you can try an alternative extension (for example .be or .eu instead of .nl), you can choose a variation on the name (e.g. yourcompanyamsterdam.nl), or you can try to approach the current owner to negotiate a takeover. Our support team is happy to help you find a suitable solution.
How do I renew my domain name and what does a renewal cost?
At Theory7 you can renew a domain name manually or automatically via your customer panel. The renewal costs are shown when you purchase your domain, but can also be found on our domain name pricing page. In MyT7 you can switch automatic renewal on or off.
Can I manage the DNS settings for my domain name myself?
Yes, at Theory7 you get full access to managing your DNS settings. You can easily add, change or delete DNS records via the control panel. This allows you to configure settings yourself for, for example, email, subdomains, or external services. Our support team is always ready to help you set up more complex DNS configurations.
How long is my domain name active after purchase?
A domain name is reserved for one year after registration. You can always renew it for another year, so you don't lose your domain. If you no longer want to use your domain name, you can cancel it via MyT7, with no cancellation fees.
What is DNSSEC and do I need it for my domain name?
DNSSEC (Domain Name System Security Extensions) is a security layer that prevents visitors from being redirected to a fake version of your website. It protects against DNS spoofing and man-in-the-middle attacks. At Theory7, DNSSEC is included for free with every domain name and is activated automatically. Especially for websites with customer data or payments, DNSSEC is an important extra security layer alongside SSL.
