One of the source is regularly dropping 9.9.9.9 as a source of
publicdns. This additional list can be used to ensure these known golden
DNS public resolver are there.
* Refactored generate_moz-top50.py
* Download all file to new /tmp file to centralize all downloads
* Add central logging to generators.log file
* Create Bash script that generates all warninglists
* Add /tmp folder and extra files to .gitignore
* Start adding exception handling in download_to_file and write_to_file
1. The CSV format has changed with the update on 2020-07-14.
2. The script also generates IPv4, IPv6, and the hostname lists at once.
3. Downloaded file added to .gitignore
The tool generate two lists, one for IPv4 (list4.json) and one for IPv6
(list6.json) to allow the user to only enable one of the two.
The list is downloaded from http://public-dns.info/ and a sample of the
list was tested with:
for dns in $( awk -F "," '{ print $1 }' < nameservers.csv ) ; do dig +noedns @$dns google.com | grep NOERROR 1>/dev/null || echo $dns ; done
~95% of the tested servers responded. So the list is not all crap.
