This is for dnsmasq versions below v2.80. For later versions you should follow these instructions.

It's important to use both domains.txt and hostnames.txt simultaneously in dnsmasq to get full coverage!

• Download the following two files (or use a daily cronjob to do it automatically)

https://raw.githubusercontent.com/notracking/hosts-blocklists/master/hostnames.txt
https://raw.githubusercontent.com/notracking/hosts-blocklists/master/domains.txt

• Add the following lines to your dnsmasq.conf

conf-file=/path/to/domains.txt
addn-hosts=/path/to/hostnames.txt

• Restart dnsmasq (reload will not update list changes) sudo service dnsmasq restart

For automatic updates and whitelisting on Debian based systems you can use the notracking update script as a daily cronjob (detailed instructions inside).
