personalDNSfilter is a DNS filter proxy written in Java. It hooks into the domain name (DNS) resolution and returns the loopback address for filtered hosts. Available for Java enabled devices including Android (based on VPN)! It supports secure DNS via DOH (DNS over HTTPS) and DOT (DNS over TLS)! The main memory usage during runtime is independent on the size of the block list. You can filter with millions of hosts, but memory usage will only be few MB!

personalDNSfilter is hosted on Github and F-Droid
personalDNSfilter is released under the GNU GENERAL PUBLIC LICENSE. Current Version is, August 17, 2019

• It can be used for filtering ads and other unwished hosts based on a host list – Thus it is a good AdBlock alternative.

• On Android devices (Android 4.2 an newer) it can be used as effective ad, malware and tracking server filter without root access!

• It works with any upstream DNS server - filtering is completely local - no phoning home or such things!


• See dnsfilter.conf file for information on how to configure the hosts filtering.

• personalDNSfilter is preconfigured with the ad host filter lists from via this link (about 2500 entries)

• In case you are interested in a very complete hosts filter, check which provides a hosts filter with about 350.000 entries including known hosts for tracking and malicious websites, etc. Find the filter download in the download section. Select a mirror from the hosts.txt download entry.


• You can run it locally on your device or centrally as DNS server in your network.

• Tested on Raspberry Pi.
