DNS Root Instances
The map below shows, for each RIPE Atlas probe, which root DNS server instance the probe ends up querying, when asking a particular root server. Each marker makes use of two colour-codings: the fill represents the region of the server, while the outline is unique to the server queried.
This is most useful for servers which use anycasting. In other words, it shows the "gravitational radius" for root DNS server instances. The colouring is used either to highlight significant (e.g. global) nodes, or to group nodes in the same region (Europe, North America, Asia, etc.). You can find the key below the map. We display measurement results only from the last day. You can click on each point to get more information.
In the case of serial renderings, the markers are colour-coded by serial.
