Name : knot-resolver Product : Fedora 28 Version : 2.4.1 Release : 1.fc28 URL : https://www.knot-resolver.cz/ Summary : Caching full DNS Resolver Description : The Knot DNS Resolver is a 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
