personalDNSfilter

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.

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