.. SPDX-License-Identifier: GPL-3.0-or-later Root on loopback (RFC 7706) --------------------------- Knot Resolver developers think that literal implementation of :rfc:`7706` ("Decreasing Access Time to Root Servers by Running One on Loopback") is a bad idea so it is not implemented in the form envisioned by the RFC. You can get the very similar effect without its downsides by combining :ref:`mod-prefill` and :ref:`mod-serve_stale` modules with Aggressive Use of DNSSEC-Validated Cache (:rfc:`8198`) behavior which is enabled automatically together with DNSSEC validation.
