DNS criptografado não ajudará você a esconder nenhuma de suas atividades de navegação. [Saiba mais sobre DNS :material-arrow-right-drop-circle:](advanced/dns-overview.md ""){.md-button} ## Provedores Recomendados 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. | Provedor de DNS | Protocolos | Logging / Privacy Policy | [ECS](advanced/dns-overview.md#what-is-edns-client-subnet-ecs) | Filtragem | Signed Apple Profile | | -------------------------------------------------------------------------- | ---------------------------------------- | ------------------------ | -------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------------------------------------ | | [**AdGuard Public DNS**](https://adguard-dns.io/en/public-dns.html) | Cleartext DoH/3 DoT DoQ DNSCrypt | Anonymized[^1] | Anonymized | Based on server choice.

![Pi-hole logo](assets/img/dns/pi-hole.svg){ align=right } **Pi-hole** is an open-source [DNS-sinkhole](https://en.wikipedia.org/wiki/DNS_sinkhole) which uses [DNS filtering](https://cloudflare.com/learning/access-management/what-is-dns-filtering) to block unwanted web content, such as advertisements. O Pi-hole foi projetado para ser hospedado em um Raspberry Pi, mas não se limita a esse "hardware". O “software” apresenta uma interface web amigável para visualizar informações e gerenciar conteúdo bloqueado.

### AdGuard Home
![AdGuard Home logo](assets/img/dns/adguard-home.svg){ align=right } **AdGuard Home** is an open-source [DNS-sinkhole](https://en.wikipedia.org/wiki/DNS_sinkhole) which uses [DNS filtering](https://cloudflare.com/learning/access-management/what-is-dns-filtering) to block unwanted web content, such as advertisements. AdGuard Home apresenta um painel web amigável para ver informações e gerenciar conteúdos bloqueados.

## Cloud-Based DNS Filtering These DNS filtering solutions offer a web dashboard where you can customize the block lists to your exact needs, similarly to a Pi-hole. These services are usually easier to set up and configure than self-hosted services like the ones above, and can be used more easily across multiple networks (self-hosted solutions are typically restricted to your home/local network unless you set up a more advanced configuration). ### Control D
![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
![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. [:octicons-home-16: Homepage](https://nextdns.io){ .md-button .md-button--primary } [:octicons-eye-16:](https://nextdns.io/privacy){ .card-link title="Privacy Policy" } [:octicons-info-16:](https://help.nextdns.io){ .card-link title=Documentation} [:octicons-code-16:](https://github.com/nextdns/nextdns){ .card-link title="Source Code" }
Downloads - [:fontawesome-brands-windows: Windows](https://github.com/nextdns/nextdns/wiki/Windows) - [:simple-apple: macOS](https://apps.apple.com/us/app/nextdns/id1464122853) - [:simple-linux: Linux](https://github.com/nextdns/nextdns/wiki) - [:simple-appstore: App Store](https://apps.apple.com/app/nextdns/id1463342498) - [:simple-github: GitHub](https://github.com/nextdns/nextdns/releases)
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 is 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, just without your filter lists. NextDNS also offers public DNS-over-HTTPS service at `https://dns.nextdns.io` and DNS-over-TLS/QUIC 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). ## Encrypted DNS Proxies 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
![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 [DNS-over-HTTPS](advanced/dns-overview.md#dns-over-https-doh), [DNS-over-TLS](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
![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), [DNS-over-HTTPS](advanced/dns-overview.md#dns-over-https-doh), and [Anonymized DNS](https://github.com/DNSCrypt/dnscrypt-proxy/wiki/Anonymized-DNS).

The anonymized DNS feature does [not](advanced/dns-overview.md#why-shouldnt-i-use-encrypted-dns) anonymize other network traffic.
## Criteria **Por favor, note que não somos parceiros de nenhum dos produtos que recomendamos.** Além de [nossos requisitos básicos](about/criteria.md), desenvolvemos um conjunto claro de requisitos para nos permitir fornecer recomendações objetivas. Recomendamos que você se familiarize com esta lista antes de escolher usar um produto, e que faça sua própria pesquisa para garantir que o produto escolhido é o ideal para você. All DNS products must support: - [DNSSEC](advanced/dns-overview.md#what-is-dnssec). - [Minimização QNAME](advanced/dns-overview.md#what-is-qname-minimization). - Anonymize [ECS](advanced/dns-overview.md#what-is-edns-client-subnet-ecs) or disable it by default.
