Free domain name check: how it works
Checking a domain name is the first step toward your online presence. The process is simple: enter your desired name, and our system checks the official domain registries within seconds to see if the name is still available. But what if your desired name is already taken? You have several options. You can try a different extension, if .nl is taken, .com or .eu might still be free. You can also try small variations by adding or changing a word. Our checker automatically suggests available alternatives that might give you ideas. Note: an available domain name can be registered by someone else at any moment, so don't wait too long.

How does a domain name work technically?
A domain name is essentially a translation of an IP address into a readable name. When someone types in your domain name, the DNS server (Domain Name System) redirects the visitor to your server's correct IP address. This process takes only milliseconds and is completely invisible to the visitor.
Tips for choosing a domain name
A good domain name is short, easy to remember and relevant to your business. Avoid hyphens and numbers where possible. Prefer a .nl extension for the Dutch market or a .be extension for Belgium. Also check whether the matching social media handles are still available.
Tips for checking domain names
Before registering a domain name, it's smart to check not just its availability, but also its history. A previously used domain name can carry a negative reputation with search engines. Use the Wayback Machine from the Internet Archive to see what the domain was previously used for.
Also check whether variations are available. If you want .nl but .com is also free, consider registering both. This prevents competitors from claiming your brand name on a different extension. At Theory7 you can register and manage more than 1500 extensions from one clear dashboard.
Tips for finding an available domain name
Finding a good domain name that's still available can be a challenge. The most obvious names are often already taken. An effective strategy is to combine your business name with a verb or adjective, or to consider an alternative extension. While .nl and .com are the most popular, extensions like .online, .shop or .tech offer creative options for a memorable domain name.
When checking availability, also watch out for possible trademark infringement. A domain name being available doesn't automatically mean you're allowed to use it. If the name closely resembles a registered trademark, you could run into problems. Use the free trademark search from BOIP (Benelux Office for Intellectual Property) to verify this before registering a domain name.
