Improved Recursive DNS Server Selection for Multi-Interfaced Nodes
RFC 6731, “Improved Recursive DNS Server Selection for Multi-Interfaced Nodes”, is a Proposed Standard document published in December 2012 by T. Savolainen, J. Kato, T. Lemon. The canonical text is published by the RFC Editor.
Abstract
A multi-interfaced node is connected to multiple networks, some of which might be utilizing private DNS namespaces. A node commonly receives recursive DNS server configuration information from all connected networks. Some of the recursive DNS servers might have information about namespaces other servers do not have. When a multi-interfaced node needs to utilize DNS, the node has to choose which of the recursive DNS servers to use. This document describes DHCPv4 and DHCPv6 options that can be used to configure nodes with information required to perform informed recursive DNS server selection decisions. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
