Encrypted **DNS** with third-party servers should only be used to get around basic [DNS blocking](https://en.wikipedia.org/wiki/DNS_blocking) when you can be sure there won't be any consequences. Encrypted DNS will not help you hide any of your browsing activity.

## 推奨するサービスプロバイダー

These are our favorite public DNS resolvers based on their privacy and security characteristics, and their worldwide performance. Some of these services offer basic DNS-level blocking of malware or trackers depending on the server you choose, but if you want to be able to see and customize what is blocked, you should use a dedicated DNS filtering product instead.

## Cloud-Based DNS Filtering

These DNS filtering solutions offer a web dashboard where you can customize the block lists to your exact needs. These services can be used easily across multiple networks.

### Control D

<div class="admonition recommendation" markdown>

![Control D logo](assets/img/dns/control-d.svg){ align=right }

**Control D** is a customizable DNS service which lets you block security threats, unwanted content, and advertisements on a DNS level.

In addition to their paid plans, they offer a number of preconfigured DNS resolvers you can use for free.

### NextDNS

<div class="admonition recommendation" markdown>

![NextDNS logo](assets/img/dns/nextdns.svg){ align=right }

**NextDNS** is a customizable DNS service which lets you block security threats, unwanted content, and advertisements on a DNS level.

They offer a fully functional free plan for limited use.

</div>

When used with an account, NextDNS will enable insights and logging features by default (as some features require it). You can choose retention time and log storage location for any logs you choose to keep, or disable logs altogether.

NextDNS's free plan is fully functional, but should not be relied upon for security or other critical filtering applications, because after 300,000 DNS queries in a month all filtering, logging, and other account-based functionality are disabled. It can still be used as a regular DNS provider after that point, so your devices will continue to function and make secure queries via DNS-over-HTTPS (DoH), just without your filter lists.

NextDNS also offers a public DoH service at `https://dns.nextdns.io` and DNS-over-TLS/QUIC (DoT/DoQ) at `dns.nextdns.io`, which are available by default in Firefox and Chromium, and subject to their default, no-logging [privacy policy](https://nextdns.io/privacy).

## 暗号化DNSプロキシ

Encrypted DNS proxy software provides a local proxy for the [unencrypted DNS](advanced/dns-overview.md#unencrypted-dns) resolver to forward to. Typically, it is used on platforms that don't natively support [encrypted DNS](advanced/dns-overview.md#what-is-encrypted-dns).

### RethinkDNS

<div class="admonition recommendation" markdown>

![RethinkDNS logo](assets/img/android/rethinkdns.svg#only-light){ align=right }
![RethinkDNS logo](assets/img/android/rethinkdns-dark.svg#only-dark){ align=right }

**RethinkDNS** is an open-source Android client that supports [DoH](advanced/dns-overview.md#dns-over-https-doh), [DoT](advanced/dns-overview.md#dns-over-tls-dot), [DNSCrypt](advanced/dns-overview.md#dnscrypt) and DNS Proxy. It also provides additional functionality such as caching DNS responses, locally logging DNS queries, and using the app as a firewall.

While RethinkDNS takes up the Android VPN slot, you can still use a VPN or Orbot with the app by [adding a WireGuard configuration](https://docs.rethinkdns.com/proxy/wireguard) or [manually configuring Orbot as a Proxy server](https://docs.rethinkdns.com/firewall/orbot), respectively.

### DNSCrypt-Proxy

<div class="admonition recommendation" markdown>

![DNSCrypt-Proxy logo](assets/img/dns/dnscrypt-proxy.svg){ align=right }

**DNSCrypt-Proxy** is a DNS proxy with support for [DNSCrypt](advanced/dns-overview.md#dnscrypt), [DoH](advanced/dns-overview.md#dns-over-https-doh), and [Anonymized DNS](https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Anonymized-DNS).
