DNS-over-HTTPS, DNS-over-TLS, and DNSCrypt resolvers will not make you anonymous. Using Anonymized DNSCrypt hides <i>only</i> your DNS traffic from your Internet Service Provider. However, using any of these protocols will prevent DNS hijacking, and make your DNS requests harder for third parties to eavesdrop on and tamper with. If you are currently using Google's DNS resolver, you should pick an alternative here. See the <ahref="#dns-definitions">definitions</a> below.

In iOS, iPadOS, tvOS 14 and macOS 11, DoT and DoH were introduced. DoT and DoH are supported natively by installation of profiles (through mobileconfig files opened in <em>Safari</em>).
After installation, the encrypted DNS server can be selected in <em>Settings → General → VPN and Network → DNS</em>.

<li><strong>Signed profiles</strong> are offered by <ahref="https://adguard.com/en/blog/encrypted-dns-ios-14.html">AdGuard</a> and <ahref="https://apple.nextdns.io/">NextDNS</a>.</li>

A security protocol for encrypted DNS on a dedicated port 853. Some providers support port 443 which generally works everywhere while port 853 is often blocked by restrictive firewalls.
Similar to DoT, but uses HTTPS instead, being indistinguishable from "normal" HTTPS traffic on port 443 and more difficult to block. {% include badge.html color="warning" text="Warning" tooltip="DoH contains metadata such as user-agent (which may include system information) that is sent to the DNS server." link="https://tools.ietf.org/html/rfc8484#section-8.2" icon="fas fa-exclamation-triangle" %}
A <ahref="https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Anonymized-DNS">lightweight protocol</a> that hides the client IP address by using pre-configured relays to forward encrypted DNS data. This is a relatively new protocol created in 2019 currently only supported by <ahref="#dns-desktop-clients">dnscrypt-proxy</a> and a limited number of <ahref="https://github.com/DNSCrypt/dnscrypt-resolvers/blob/master/v3/relays.md">relays</a>.
