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, just start the local DNS socket: BEWARE: Because of https://bugzilla.redhat.com/show_bug.cgi?id=1366968 you need to switch your system to SELinux permissive mode.
