Hello everyone, I spoke to Olafur about this idea in Hiroshima last year. I'm afraid the deadline for Anaheim already passed, but we hope we can discuss it on-line in the meantime and decide if it should become a WG item in Maastricht later this year. To summarize the I-D: It specifies an EDNS0 option that carries IP address information (by default only the first 24 bits to preserve privacy) of the user that triggered a DNS resolution. This should allow authoritative nameservers that give geo-targeted responses to be more accurate, even in cases where the resolver and its users aren't close to each other. To preserve the ability to cache such responses efficiently, the option in the response can indicate which exact subnet it should be cached for. Comments are more than welcome.
