There are two report sets for the resolver use reports: per country/region and per network. This document describes the common format used for these reports.

A common record format is used for all of these reports. Each record in the report contains the data for one day. The record format is:

  1. Date (yyyy-mm-dd)
  2. cc - Two letter country code - the full list of country and regions is below. Dor an AS report this is two fieds, the AS number and the country code.
  3. Type of measurement. This can be one of three "types":
  4. Seen - the number of measurements for this country or network on this date
  5. Resolver counts - a vector of counts for each reolver type - see the list below for the list ordering
  6. Weighted Seen count - the ad system is not evenly balanced across all countries. This weighted count is the total seen count in the hypothetical case that the measurement ewas made on a uniform per capita basis across all countries and networks
