How To Install unbound on Fedora 34
Introduction
In this tutorial we learn how to install unbound on Fedora 34.
What is unbound
Unbound is a validating, recursive, and caching DNS(SEC) resolver. The C implementation of Unbound is developed and maintained by NLnet Labs. It is based on ideas and algorithms taken from a java prototype developed by Verisign labs, Nominet, Kirei and ep.net. Unbound is designed as a set of modular components, so that also DNSSEC (secure DNS) validation and stub-resolvers (that do not run as a server, but are linked into an application) are easily possible.
We can use yum or dnf to install unbound on Fedora 34. In this tutorial we discuss both methods but you only need to choose one of method to install unbound.
