Terms of Use

As of: June 2026

1. Scope

These terms of use govern the use of the services provided by Yannick Dreher – namely the public DNS resolvers (DNS-over-TLS and DNS-over-HTTPS) and the authoritative DNS hosting for your own zones (together hereinafter the "service") – and the associated website. By using the service, the user agrees to these terms.

2. Public DNS resolvers

The service provides recursive DNS resolution over encrypted transport channels. The service is offered free of charge and without any contractual obligation as a private initiative.

There is no entitlement to availability, functionality, specific response times or DNSSEC validation. The operator reserves the right to discontinue, modify, restrict or make the service inaccessible at any time, in whole or in part, without prior notice.

3. Authoritative DNS hosting

The service enables registered users to host their own DNS zones authoritatively and to manage their records, optionally collaboratively within organisations with multiple members and graduated permissions. Hosting is offered free of charge and without any contractual obligation as a private initiative; there is no entitlement to availability, functionality or data preservation.

The user may only host domains over which they themselves are authorised to dispose. The operator may require proof of ownership (domain verification) and may block or delete zones without successful proof.

The user is solely responsible for the content and the lawfulness of the DNS records they create and the services reachable through them. The operator does not carry out any content review and assumes no liability for this.

Within an organisation, members act within the scope of the roles assigned to them. The person managing the organisation is responsible for assigning permissions carefully and for removing members who have left.

Upon deletion of a zone or the account, the associated hosting data is removed; the authoritative resolution of the affected domains thereby ends. The operator assumes no liability for any resulting consequences (e.g. unavailability of services).

4. Permitted use

The service may only be used within the scope of applicable laws and the supplementary Acceptable Use Policy. The following is in particular prohibited:

any use for unlawful purposes;
measures suitable for impairing the stability, security or integrity of the service or third parties (e.g. DNS amplification, spoofing, load attacks);
circumventing technical protective measures, rate limits or blocks;
hosting domains over which you are not authorised to dispose;
creating DNS records for unlawful, misleading or abusive purposes (e.g. phishing, distribution of malware, command-and-control infrastructure);
commercial resale of the service as your own offering without the operator's express written consent.

5. Blocking and termination

The operator is entitled to throttle, block, delete or exclude individual IP addresses, network ranges, query types, accounts, organisations or zones from the service at any time without prior notice, in particular in case of violations of these terms or the Acceptable Use Policy or when the operation is endangered.

6. Data protection

Information on the processing of personal data can be found in the Privacy Policy.

7. Liability

The operator is liable without limitation for damages arising from intent and gross negligence, for injury to life, body or health and according to the provisions of the Product Liability Act and within the scope of an assumed guarantee.

In case of slight negligence, the operator is only liable for the breach of essential contractual obligations (so-called cardinal obligations). In this case, liability is limited in amount to the foreseeable, contract-typical damage.

Any further liability – in particular for lost profits, indirect damages, consequential damages, data loss or damages arising from non-availability of the service – is excluded as far as legally permissible. The above limitations of liability also apply in favour of the operator's vicarious agents.

8. Third-party content

As a resolver, the service technically forwards DNS queries to authoritative nameservers and transmits their responses. The operator assumes no responsibility for the contents held under the resolved domain names. The same applies to content reachable through zones hosted by users; the respective user is solely responsible for this.

9. Changes to the terms of use

The operator reserves the right to amend these terms at any time. The respective current version is available on this page and is deemed accepted with continued use of the service.

10. Applicable law and place of jurisdiction

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Consumers are entitled to mandatory protective provisions of the law of their country of residence in full.

As far as legally permissible, the exclusive place of jurisdiction for all disputes arising from or in connection with these terms of use is Nuremberg.

11. Severability clause

Should individual provisions of these terms of use be or become wholly or partly invalid, this shall not affect the validity of the remaining provisions.
