Unbound is a recursive-only caching DNS server which can perform DNSSEC validation of results. It implements only a minimal amount of authoritative service to prevent leakage to the root nameservers: forward lookups for localhost, reverse for 127.0.0.1 and ::1, and NXDOMAIN for zones served by AS112. Stub and forward zones are supported. In this guide, I will show you how to install unbound on Ubuntu 22.04.

Prerequisites to install
