DNS filter


View all my projects »

Proxy for non-compliant DNS servers.

DNS-filter is a simple blacklisting DNS proxy that returns NXDOMAIN if the master offers an IP from a specified blacklist.

This is useful for broken ISPs (or "open" services) that have an obnoxious "The page you were looking for cannot be found" website for all unregistered domains.


You can browse the source tree, create or file bugs or download the code from Git:

$ git clone

DNS filter is released under the GNU General Public license version 3 or later.
