Which name servers are authoritative for the .de zone?

DENIC is responsible for operating the name servers for the Top Level Domain .de. The following name servers are authoritative for this zone:

Why does DENIC not make available the zone files for .de?

The DENIC zone files contain – roughly spoken – a list of all .de-domains together with information on the name servers that belong to them. DENIC does not hand over these zone files (or parts of it) to any third parties. Such disclosure would run counter to the imperatives of data protection and would undermine the defence of domain holders against possible abuse. Germany's Federal Data Protection Act is rather far-reaching in this respect. Protected "person-related data" includes not only information that is related directly to a particular individual, but also any data that could be used to identify individuals. Since it would be easy to combine the zone file with DENIC's whois query to extract data and to link them to individuals, the data contained in the zone file is protected because it is person-related.

Generally, DENIC collects and processes data about domains and their holders solely for the purpose of domain administration, and that does not require the zone file to be published. Moreover, from the perspective of domain administration, there are no circumstances in which a third party could justifiably need such a file. On the contrary: there would be a big danger of the zone file being used for activities that might jeopardize the interests of domain holders. Spammers or hackers might use it easily as a data source, since there are all existing .de-domains listed in the zone file. Combined with the whois query, these domain data could be person-related. Once the zone file had been published or rendered publicly available, DENIC would have lost any means of monitoring or influencing its use or of establishing and preventing any breaches of others' rights. Even the copyright that DENIC holds for the zone file, prohibiting unauthorized copies and further dissemination, would not provide any real protection.

In this respect, DENIC can be reasonably compared with a bank. No bank publishes a complete list of all the account numbers it has issued; in the same way, DENIC does not make the zone files available either.

What are the organizational steps involved in a provider change?

A provider change runs in two phases: First you request your current provider to obtain an AuthInfo. Then the new provider can use this AuthInfo to move the domain.

At least four parties are involved in a provider change. These are the DENIC member who has been administering the domain to date, the DENIC member who is to take over administration in future, the domain holder and DENIC. If either the current provider and/or the future provider is not a member of DENIC, they will also both be involved in the process.

You, the domain holder, start the provider change process by telling your current provider that you want another provider to administer your domain in the future. In the next step, the current provider sends an AuthInfo to DENIC. If this provider is not a DENIC member, they first of all send the application to create an AuthInfo to the DENIC member with whom they cooperate. This member then forwards the application to DENIC. Before submitting any such application, the current provider must make sure that the change was really initiated by the domain holder and not by a third party.

You, as the domain holder, send the AuthInfo to your new provider, who will use it for the provider change request. Then the provider change is implemented and the data in DENIC's database are updated accordingly.

I would like to change providers. What do I have to do and what do I have to bear in mind?

The initial request for the registration of a .de domain can only be submitted to DENIC through a company that is a member of the DENIC Cooperative or through our DENICdirect service. The same applies to any administrative measure affecting existing domains: it is still the same DENIC member or DENICdirect that is in charge. The DENIC member (or DENICdirect) in charge of administration is entered in the domain data at DENIC and is the sole organisation that has the right to submit orders from the domain holder to us to edit the domain data (such as a change of address or a deletion). If your provider is not on the list of DENIC members, they will cooperate with a DENIC member or with DENICdirect.

If you want to change providers, you should inform your current provider about your intention and request creation of an AuthInfo. The current provider will check if the request is issued by an appropriately authorised party (the domain holder or legal representative). The future provider will then submit a provider transfer request together with the AuthInfo to DENIC or, if they are not a DENIC member to the DENIC member with whom they cooperate. This request is then processed by DENIC and the domain is assigned to the new provider.

Sometimes delays occur at this point. They may be due to one of the reasons listed below:

  • You have informed your current provider about the intended transfer, but that provider has not yet recorded an AuthInfo.
  • You have forgotten to inform your current provider.
  • Your provider needs some clarification and cannot get in touch with you.

In all such cases, check whether an AuthInfo has been stored for the domain and whether you have received it. Your provider will certainly help you to solve any problems.

Please be aware of the following: In the past, there have been repeated cases when domain holders tried to change providers by terminating their contract with the first provider, authorising him to delete the domain, and then getting a second provider to register it again, on their behalf. Please note that a domain, following its deletion, can only be retrieved within a 30-day time limit - the so-called Redemption Grace Period (RGP) - by its former holder. Otherwise, as soon as the 30-day Redemption Grace Period ends, the subject domain will be released and will then be available again for registration by any interested party.

If you have any questions about the cost of a provider transfer, please contact your provider. Each provider defines potentially applicable fees themselves.

What is a Provider Change?

The term "Provider Change" is used when administration of a domain is transferred from one provider to another. Since the order to register a .de can only be submitted to DENIC through a member of DENIC or through our DENICdirect service, the provider change (CHPROV) transaction at DENIC refers to the transfer of responsibility for administering the domain from a member or DENICdirect to another member or DENICdirect. The DENIC member in charge or DENICdirect is entered by DENIC in the domain data. This DENIC member handles all communications with DENIC about the domain on behalf of the domain holder. Only this member is authorized to submit any customer orders to DENIC that might lead to modifications in the domain data.
