Fetch various blocklists and generate a BIND zone from them.

Configure BIND to return NXDOMAIN for ad and tracking domains to stop clients from contacting them.

To install

Configure BIND

Add the response-policy statement to the BIND options

// For AdBlock
response-policy {
	zone "rpz.example.com";
};

Add your rpz zone. Replace example.com with a domain of your choice.

// AdBlock
zone "rpz.example.com" {
	type master;
	file "/etc/bind/db.rpz.example.com";
	masterfile-format text;
	allow-query { none; };
};

Create a zone file for your zone. Replace example.com with the domain you used before.

@ 3600 IN SOA @ admin.example.com. 0 86400 7200 2592000 86400
@ 3600 IN NS ns.example.com.
