An Effective Host Blocker for Android
DNS66 is a host blocker based on DND. Built for Android, the tool blocks malware, ads, and other weird things by default. It works by establishing a VPN service, with all DNS servers’ routes diverted to it. You may install the tool through F-Droid, with the help of the F-Droid official repository. Also, you can download its apk files. Items in the DNS server and hosts lists can be removed and moved around using RecyclerView interactions. A later entry, for hosts, overrides a prior entry; for DNS servers, the initial server is preferred.
