-----------------------------+----------------------------------
 Currently, OONI measurements are not anycast aware. When a domain resolves
 to an IP which is served by multiple servers depending on geographic
 location, we have no way to determine which actual server the client
 attempts to contact, or where it is.

 This is a broad issue, and there are several smaller components that need
 to be addressed to do a reasonable job of resolution.
 First, we need to know which IPs are anycasting, then we need to know the
 locations of the different servers, and finally we need to know which
 clients are routed to which servers.
