Valid domain names[Link]

Before registering domain names, you should take these points into account:

  • Domain names you register for your clients should be registered in your client’s name and not in your name!

  • Please make sure your clients accept our ‘Terms & Conditions’ before they can proceed with the registration of a domain name. This is also the case for a transfer.

Domain names must meet with a number of technical requirements:

  • Valid non-IDN names are:

    • minimum 2 characters among the letters ‘a to z’, the numbers ‘0 to 9’ and the hyphen ‘-‘;

    • maximum 63 characters;

    • must not begin or end with a hyphen;

    • must not contain a hyphen ‘-‘ on the 3rd AND 4th position.

  • Valid IDN names are:

    • The U-label is minimum 2 characters and the A-label and/or U-label is maximum 63 characters.

    • The U-label can’t begin or end with a hyphen.

    • The U-label must not contain a hyphen on the 3rd AND 4th position.

    • The U-label may only contain characters for the list of allowed characters

Allowed characters[Link]

The implementation of IDN at DNS Belgium is based on the IDNA 2008 standard.

There are different character sets that can be used for an IDN implementation. DNS Belgium decided to use a set that includes, at the very least, all accented letters used in Dutch, French and German. This particular set also includes accented letters used in other European languages, such as Swedish, Danish and Finnish.

We also accept IDN for name servers. In the name server name, the same characters are allowed as in domain names.

For reference, this is the list of allowed characters

Domain status[Link]

A domain name can have one of following statuses:

  • AVAILABLE: Domain name is available for registration.

  • REGISTERED: Domain name is in use, therefore not available for registration; the registrar manages the domain.

  • QUARANTINE: When a domain is deleted, the domain name will go into a quarantine period of 40 days. A domain in quarantine is not available for registration. It can only be reactivated or ‘transferred from quarantine’ within these 40 days. For more information look at the chapter: ‘DELETE, QUARANTINE AND REACTIVATE’.

  • OUT OF SERVICE: This is an exception of REGISTERED. It means the domain name’s registrar stopped (due to failure or termination of its contract) and the domain name’s due date has passed. The right of use of these names can only be renewed through a new registrar.

  • ON HOLD: This is an exception of REGISTERED, this means an ADR (Alternative Dispute Resolution, i.e., in Cepina) procedure or lawsuit is pending. This has no implication to the outside world because the domain stays active. However, only the commands ‘delete-domain’, ‘undo-delete-domain’, ‘update-domain’ (no registrant update), ‘reactivate-domain’ will be usable. This allows the registrar to handle the domain according to its needs. If a domain name is deleted, the quarantine period of 40 days starts running from the moment the ‘ON HOLD’ flag is removed.

  • NOT VALID: The domain name does not meet the requirements as specified in our End Terms and Conditions, e.g. the domain name requested is longer than 63 characters.

A domain name with status OUT OF SERVICE has the following lifecycle:
