Extract DNSSEC support statistics for the top 1 million hosts of the Alexa database.
The tool wraps dig to check, for each host present in an input file
(top-1m.csv), whether an RRSIG record is present in the command output.
You can grab a fresh copy of the list of the top one million websites
here. At the time of
speaking (September 2016), 4.6194% of the hosts have an RRSIG record.
Install the Go release and clone this repository.
The tool expects a top-1m.csv file to be present in the current directory.
Launch using:
go run dnssec-stats.go
The detailed results are saved to a results.csv file.
dnssec-stats defaults to 100 concurrent workers, each of them spawning dig
processes for a couple of hours, thus the execution is quite CPU-intensive. Feel
free to adjust the number of workers in the main function if you want to
reduce the load (the overall execution time will increase).
