Mischback / bind-adblock

Use the BIND DNS server to block ads

BIND ad blocker

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.

Requires BIND 9.8 or newer for RPZ support.

Uses the following sources:

• Peter Lowe’s Ad and tracking server list
• Malware domains
• MVPS HOSTS
• Adaway default blocklist
• hpHosts Ad and Tracking servers only
• Dan Pollock’s hosts file
• MalwareDomainList.com Hosts List
• StevenBlack Unified hosts file
• CAMELEON
• Disconnect.me Basic tracking list
• Disconnect.me Ad Filter list
• SANS ISC - Suspicious Domains Low Sensitivity

Setup

Python packages

• requests
• dnspython

These packages need to be installed to run the update script.

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.
