Unbound (Install)

Unbound is a validating, recursive, caching DNS resolver. It is designed to be fast and lean and incorporates modern features based on open standards. Late 2019, Unbound has been [rigorously audited](https://ostif.org/our-audit-of-unbound-dns-by-x41-d-sec-full-results/), which means that the code base is more resilient than ever.
