Unbound is a validating, recursive, and caching DNS resolver. In this tutorial, we will guide you through the process of installing Unbound on Alpine Linux Latest.
Before we start with the installation process, ensure that you have an internet connection and a user account with sudo privileges.
Update the system package list by running the following command:
sudo apk update
Install the unbound package by running the following command:
sudo apk add unbound
The default configuration file of Unbound is located at /etc/unbound/unbound.conf. You can edit this file and customize the Unbound configuration as per your requirements. For example, you can set the root-hints file path or add DNS-over-TLS/HTTPS servers.
sudo nano /etc/unbound/unbound.conf
Once you have modified the configuration file, save the changes and exit the text editor.
After completing the configuration, start the Unbound service by running the following command:
sudo rc-service unbound start
You can check the status of the service by running the following command:
sudo rc-service unbound status
To use Unbound as your default DNS resolver, update /etc/resolv.conf and add the following line:
nameserver 127.0.0.1
Note that some Linux distributions may automatically overwrite this file. In this case, you need to modify the configuration file of your specific Linux distribution.
In this tutorial, we have successfully installed and configured Unbound on Alpine Linux Latest. You can now use Unbound as your default DNS resolver and enjoy its features such as DNSSEC validation, DNS-over-TLS/HTTPS, and caching.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
