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.
