The IESG has approved the following document: - 'Running a Root Server Local to a Resolver' (draft-ietf-dnsop-7706bis-12.txt) as Informational RFC This document is the product of the Domain Name System Operations Working Group. The IESG contact persons are Warren Kumari, Barry Leiba and Ignas Bagdonas. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-dnsop-7706bis/ Technical Summary: This document shows how to start and maintain a local copy of the root zone that reduces round-trip times for certain queries, reduces the risk of third-party observation of DNS queries and responses, and does not cause problems for other users of the DNS, at the cost of adding some operational fragility for the operator. It updates RFC 7706 with additional operator experience in using the described techniques. Working Group Summary: The original RFC 7706 was published in 2015 as guidance to resolver operators to help them provide local resolution of lookups in the root zone, which has become increasingly popular as a resiliency mechanism for DNS operations, but which can also lead to new failures that might be difficult to troubleshoot. The technique was largely undocumented at the time. The WG expected that a -bis document would be useful with more experience, and has been correct in this assessment, so insight from that further experience is presented here. The WG has thoroughly discussed the document and both authors have been responsive and accurate in their work on it. Document Quality: The document is based on RFC 7706 and clearly states the premise for going beyond it-- 7706 specified one mechanism, local root server on loopback, for the local root cache; 7706bis discusses others, including operational requirements for configuration to provide the desired service and avoid the pitfalls.
