Archived-At: List-Archive: List-Help: List-Owner: List-Post: List-Subscribe: List-Unsubscribe: http://tinyurl.com/ip-geo-submitted to and accepted at iab ip-geo workshop, and following dave's approach, open comments and feedback welcome at http://tinyurl.com/ip-geo-updated . thanks GeoFeed is very important in today's Internet to assist geo-relevant content delivery and service differentiation, however, the adoption, quality and use of GeoFeed vary a lot among network and content providers, and shall be greatly improved for a more correct, accurate and consistent user experience. This position paper focuses on a case study on StarlinkISP.net, the Internet service provider of Starlink.com, a division of SpaceX.com, given its fast growth in low-earth-orbit satellite networks, demonstrating some of the intrinsic weaknesses and problems in the current GeoFeed RFC and practice. More importantly, the assumption that users and their PoP are close enough cannot be guaranteed in today's Internet with the emerging non-terrestrial networks. Thus we call for IAB and IETF, together with network, content and IP-geo providers, to come up with appropriate guidelines. -- J Pan, UVic CSc, ECS566, 250-472-5796 (NO VM), Pan@UVic.CA, Web.UVic.CA/~pan
