The IESG has received a request from the Domain Name System Operations WG (dnsop) to consider the following document: - 'Chain Query requests in DNS' <draft-ietf-dnsop-edns-chain-query-05.txt> as Experimental RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2016-01-18. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document defines an EDNS0 extension that can be used by a security-aware validating Resolver configured to use a Forwarder to send a single query, requesting a complete validation path along with the regular query answer. The reduction in queries lowers the latency and reduces the need to send multiple queries at once. This extension mandates the use of source IP verified transport such as TCP or UDP with EDNS-COOKIE so it cannot be abused in amplification attacks. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-dnsop-edns-chain-query/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-dnsop-edns-chain-query/ballot/ No IPR declarations have been submitted directly on this I-D.
