Name : knot-resolver
Product : Fedora 30
Version : 4.3.0
Release : 1.fc30
URL : https://www.knot-resolver.cz/
Summary : Caching full DNS Resolver
Description :
The Knot Resolver is a DNSSEC-enabled caching full resolver implementation
written in C and LuaJIT, including both a resolver library and a daemon.
Modular architecture of the library keeps the core tiny and efficient, and
provides a state-machine like API for extensions.

The package is pre-configured as local caching resolver.
To start using it, start a single kresd instance:
$ systemctl start kresd@1.service
