Hi Dave,

Thanks for your feedback, :-)

We plan to contact authoritative server implementers and public recursive
implementers, for further realistic using, welcome cooperation.

Not "switch to", but we can try to add *an alternative solution* for
GeoIP-enabled Authoritative Nameserver  *with user privacy concern*.
CDN can do all analysis based on client ip *without ECS and EIL*, because
it is data provider, every client will visit.

The < COUNTRY, AREA, ISP > tuple *can be sufficient for GeoIP-enabled
Authoritative Nameserver*, because the Authoritative Nameserver map client
ip into geolocation, and then return the tailored response based on
geolocation, such as  Appendix A. GeoIP-enabled Nameservers Example
<https://tools.ietf.org/html/draft-pan-dnsop-edns-isp-location-02#section-10>
.

More details in  Section 1.1 Path Calculation and Tailored DNS Response
<https://tools.ietf.org/html/draft-pan-dnsop-edns-isp-location-02#section-1.1>
