Container Info
pihole-unbound
A Linux network-level advertisement and Internet tracker blocking application which acts as a DNS sinkhole. This version has Ubound software installed on it so you don't need to rely on external DNS providers. When the installation is complete, navigate to your.ip.goes.here:1010/admin. Follow the article <a href='https://medium.com/@niktrix/getting-rid-of-systemd-resolved-consuming-port-53-605f0234f32f'>here</a>

More DNS Clients
-
A flexible DNS proxy, with support for modern encrypted DNS protocols including DNSCrypt V2, DNS-over-HTTPS and Anonymized DNSCrypt. Also allows for advanced monitoring, filtering, caching and client IP protection through Tor, SOCKS proxies or Anonymized DNS relays.
-
Non-root, small-sized DNS changer utilizing DNS-over-HTTPS and DNS-over-TLS. (Note, since this uses Android's VPN API, it is not possible to run a VPN while using Nebulo.)
-
Free and open source DNS changer with support for DNS-over-HTTPS, DNS-over-Tor, and DNSCrypt v3 with Anonymized Relays. (Note, since this uses Android's VPN API, it is not possible to run a VPN while using RethinkDNS + Firewall.)
-
Simple all that allows for the use for dnscrypt-proxy 2 on an iPhone.
-
Stubby
(Desktop [Linux, Mac, OpenWrt & Windows])
dnsprivacy.org/wiki/display/DP/DNS+Privacy+Daemon+-+StubbyActs as a local DNS Privacy stub resolver (using DNS-over-TLS). Stubby encrypts DNS queries sent from a client machine (desktop or laptop) to a DNS Privacy resolver increasing end user privacy. Stubby can be used in combination with Unbound - Unbound provides a local cache and Stubby manages the upstream TLS connections (since Unbound cannot yet re-use TCP/TLS connections), see example configuration.
