+Name:DNS66
+Summary:Ad- and Host Blocking via DNS
+Description:
+DNS66 allows blocking host names via DNS. This can be used for ad blocking. It
+also allows other DNS servers to be added, for more privacy.
+
+Compared to AdBlock Plus, this works without proxy stuff; and it also does not
+require root, like AdAway does: DNS66 establishes a VPN interface, and redirects
+DNS server traffic to it. The VPN interface filters the traffic, only allowing
+queries for hosts that are not blacklisted.
+
+A host (list) can be configured as allow, deny, or ignore. A later entry in the
+list overrides a previous entry.
+
+Custom DNS Servers can be configured as well, using the same UI, but no
+differentiation is made between ignored and denied servers.
