# systemd-resolved

`systemd-resolved` is a system service provided by `systemd` that implements network name resolution to local applications. It acts as a local DNS resolver and can handle various DNS-related tasks, including the validation of DNSSEC.

## DNSSEC Integration
In modern Linux distributions, `systemd-resolved` is the default resolver. DNSSEC can be activated by setting `DNSSEC=yes` in `/etc/systemd/resolved.conf`.

### Version-Specific Requirements
For older versions of systemd (specifically versions prior to 236, such as those found in Debian 9), the system may not automatically route DNS queries through the stub resolver. In these cases, the `/etc/resolv.conf` file must be manually configured to use the local address `127.0.0.53`.
