Internet-Draft draft-pan-dnsop-edns-isp-location-05.txt is now available. Title: ISP Location in DNS Queries Authors: Lanlan Pan Yu Fu Cuicui Wang Name: draft-pan-dnsop-edns-isp-location-05.txt Pages: 24 Dates: 2024-01-15 Abstract: Nowadays, many authoritative servers support GeoIP feature, they guess the client's geolocation by the client subnet of EDNS Client Subnet (ECS) or by the source IP address of DNS query, return tailor DNS response based on the client's geolocation. However, ECS raises some privacy concerns because it leaks client subnet information on the resolution path to the authoritative server. This document describes an improved GeoIP solution, defines an EDNS ISP Location (EIL) extension to address the privacy problem of ECS, tries to find the right balance between privacy improvement and user experience optimization. EIL is defined to convey isp location < COUNTRY, AREA, ISP > information that is relevant to the DNS message. It will directly provide sufficient information for the GeoIP-enabled authoritative server as ECS, decide the response without guessing client's geolocation.
