Priming module

The module for Initializing a DNS Resolver with Priming Queries implemented according to RFC 8109. Purpose of the module is to keep up-to-date list of root DNS servers and associated IP addresses.

Result of successful priming query replaces root hints distributed with the resolver software. Unlike other DNS resolvers, Knot Resolver caches result of priming query on disk and keeps the data between restarts until TTL expires.

This module is enabled by default; you may disable it by adding modules.unload('priming') to your configuration.
