# Nutzung von DNSSec

This source provides guidance on enabling and using DNSSEC (Domain Name System Security Extensions) on client systems within the Universität Greifswald network.

## Key Technical Points
- **Client-Side Inactivity**: DNSSEC is typically not active by default on client systems during name resolution.
- **Necessity**: Enabling DNSSEC validation is required for specific applications, such as the use of SSH fingerprints.
- **Authoritative Nameservers**: Clients cannot receive a DNSSEC-validated response by querying an authoritative nameserver (the server responsible for the requested zone) directly.
- **Solution**: The use of **Local DNS Resolvers** is recommended to enable DNSSEC validation on client systems.

## Platform Support
The documentation provides detailed guides for:
- **Linux**
- **macOS**

While Windows is mentioned, no detailed instructions are provided in this specific document.

Support for these configurations is provided by the [[universitatsrechenzentrum-urz]] via their ticket system and hotline (ext. 1420).
