The M6 metrics tracks the health of three set of registries maintained by IANA: the Domain Name System (DNS) Parameters, the Domain Name System Security (DNSSEC) Algorithm Numbers, and the DNS-Based Authentication of Named Entities (DANE) Parameters. Each of these groups includes different parameter sets. We will track the health of each of these parameters by a set of metrics of the form “M6.N.X.*”, where “M6.N.X” is the metric index composed of the registry name “N” and the parameter set index “X”. The following tables present the value of the metrics M6.N.X.1 and M6.N.X.2:
In the following table, the current value is the value of the usage metric for the current month. The average value is the average value of that metric over the 12 months preceeding this one -- or the average since the beginning of measurements if measurements started fewer than 12 months ago.
The metrics M6.X.N.3 track the occurences in live traffic of specific values defined in the registries. In the following tables, we present for each registry the relative frequency of each parameter. The average value is the average value of that parameter's frequency over the 12 months preceeding this one -- or the average since the beginning of measurements if measurements started fewer than 12 months ago.
