Ett exempel är Open DNS Family som har ip-adresserna respektive 208.67.220 2021-01-01 CDN authoritative servers consider geolocation of IPs making content requests (DNS queries) to decide which content cache is best. Without ECS, a CDN authoritative server only has the resolver’s IP address to decide which content cache is nearest. In this case, the authority doesn’t know that there is a content source closer to subscribers. DNS root servers are a crucial part of the entire DNS and for that matter, the Internet, but there isn’t that much information about them available. There are also a few myths floating around. So today, we’ll learn what root servers are, what they do and how many of them are really out there. DNS servers in United States.

While some privacy leakage is an inherent cost of ECS, we show that some resolvers erode user privacy unnecessarily via probing strategies they use to EDNS-Client-Subnet (ECS) is a draft informational RFC that uses the EDNS0 extensions to the DNS. Recursive DNS services that support ECS can provide the client (end-user) subnet as part of the DNS query, allowing authoritative DNS providers to use this extra information to make more informed traffic routing decisions. 2 level 1 17 rows Many privacy oriented DNS services do not support ECS, so the only information the authoritative DNS server has, is the location of your recursor.

In this paper, we study the ECS behavior of ECS-enabled recursive resolvers from the perspec-tives of the opposite sides of a DNS interaction, the authoritative DNS servers of a major CDN and a busy DNS resolution service. Since June 2014, Google Public DNS automatically detects nameservers that support EDNS Client Subnet (ECS) options as defined in the IETF draft (by probing name servers at a low rate with ECS queries and caching the ECS capability), and will send queries with ECS options to such name servers automatically. 2021-03-06 Welcome to Elastic Cloud Server.
