Client Subnet in DNS Queries

Metadata

Publisher: IETF
Doc Type: Informational
Pages: 30
Abstract: This document describes an Extension Mechanisms for DNS (EDNS0) option that is in active use to carry information about the network that originated a DNS query and the network for which the subsequent response can be cached. Since it has some known operational and privacy shortcomings, a revision will be worked through the IETF for improvement.
