The WHOIS service provides the necessary information for people seeking to contact the registrant of a domain (or registrar contact) for problem solving etc. As WHOIS is a public service, DNS Belgium has put some limits on the number of queries in each time frame.

It is also possible to retrieve domain name information using the EPP interface. This interface allows for more detail and controlled information. We encourage registrars to use this interface to retrieve information on domain name status and other information.

Command-line WHOIS[Link]

Connection strings for the WHOIS service are available here

The information provided is limited. The service reacts as described below.

The protocol for WHOIS is: the domain name being queried with the trailing “.vlaanderen” or “.brussels”.

Available information:

  • If the status is AVAILABLE or NOT ALLOWED, Domain not found returned.

  • If the domain status is NOT AVAILABLE, information about the domain name is returned:

    • Domain name, containing the U-label in case of an IDN name

    • A-label, only if it concerns an IDN name

    • Dates associated with the domain name, such as creation date and updated date

    • Registrar

    • Domain status

    • Registrant contact

    • Admin contact

    • Technical contact

    • Name servers

    • DNSSEC status

The response always ends with the last updated date of the WHOIS database.


  • For the registrant, only state/province and country are available.

  • No information for admin and technical contact.

  • Rate limit: 100 queries per second with a leaky bucket system.

  • Quota: 10.000 queries per IP/day.


Unix/Linux users can use the regular whois script with the following parameters:

whois -h whois.nic.vlaanderen -p43 nic.vlaanderen
whois -h whois.nic.brussels -p43 nic.brussels
  • h to specify the WHOIS server to use

  • p the port to use (standard WHOIS port is 43)

Others can use the simple web based WHOIS.

Web based WHOIS (simple)[Link]

A simple web service is available on the same host via https protocol.

Public website whois services[Link]

On the DNS Belgium website it is possible to check the availability of a domain name and view domain name details.

Availability service[Link]

The web based check is available on the top of our public website homepage. The user fills in the domain name and clicks the “check availability” button.

Possible actions[Link]

When a domain name is available, the end user can look for a registrar to register the domain name.

At first, the end user sees randomly 6 registrars with their logos and potentially a short description. When the end user clicks on a logo, he or she is sent to the sales page of the registrars’ website where the domain name is already filled in. If the end user wants to see more options, it’s possible to expand the list of logos to all participating registrars. Finally, the end user can still go to the entire list of registrars where no logos are shown. Here, you can filtering on registrars is done according to country and/or tld. The result list is ordered alphabetically, but can be reversed if needed.

Every registrar can appear in the random list with their logo. To do so, you’ll need to provide the following things:

  • a working link:

    • for at least one language (Dutch, French and/or English)

    • Following keys can be used in the link:

      • ${domain}

      • ${domain_without_tld}

      • ${tld}

    • Examples:

      • https://www.thebestregistrar.be/register-your-domain/${domain}

      • https://order.thebestregistrar.com/?tld=${tld}&domain=${domain_without_tld}

  • a logo:

    • png or jpeg format

    • transparent background

    • preferably 220x55px (or a multiple)

    • no whitespace at the edges

  • short personal bio:

    • maximum 100 characters

    • description of services, where available

    • no promotional messages

    • no reference to competitors

For more information, you can send an e-mail to registrars@dnsbelgium.be.

  • Domain Status

  • Dates associated with the domain name, such as creation date and updated date

  • Registrant Contact

  • Registrar

Possible actions[Link]

If you have a complaint regarding the WHOIS details of the domain name, you can file a complaint via this page.

If you want to contact the registrant of the domain name, you can do this via the contact form. Please note the registrant is not obligated to give you an answer.

The registrant of the domain name can request a certificate from DNS Belgium here. The registration certificate provides the details of the private individual or organisation who/which is registered as the registrant of the .be domain name, as stated in DNS Belgium’s registration system, at the time the document is requested. The certificate, containing the U-label of the domain name in lower case, is sent to the e-mail address of the registrant.


DNS Belgium reserves the right to change the limits for WHOIS if we feel that the services are being abused/attacked.
