Hi We have submitted a new draft which attempts to formalize an idea that has been kicking around for a couple of years, namely to use serial number information from DNS responses to determine whether stale records in a cache can be refreshed without the need for an upstream query.
Please send comments and feedback to the list.

Name: draft-muks-dnsop-dns-opportunistic-refresh Revision: 00 Title: DNS Opportunistic Refresh for Resolvers Document date: 2017-06-29 Group: Individual Submission Pages: 9 URL: https://www.ietf.org/internet-drafts/draft-muks-dnsop-dns-opportunistic-refresh-00.txt Status: https://datatracker.ietf.org/doc/draft-muks-dnsop-dns-opportunistic-refresh/ Htmlized: https://tools.ietf.org/html/draft-muks-dnsop-dns-opportunistic-refresh-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-muks-dnsop-dns-opportunistic-refresh-00 Abstract: This document describes a mechanism whereby a DNS resolver can opportunistically refresh the TTLs of cached records of a zone using serial number information carried in responses from the zone's nameservers. As well as improving resolver response time by reducing the need to make upstream queries, the mechanism can also reduce the workload of authoritative servers. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
