Overview

Standard DNS (Domain Name System) broadcasts every website you visit to your ISP, router, and network administrators. Encrypted DNS (DoH/DoT) encrypts DNS queries, preventing surveillance of your browsing. This guide shows how to configure encrypted DNS on all major devices and provides provider comparison with privacy ratings.

Prerequisites

Before you begin, make sure you have the following ready:

Step 1 - The DNS Privacy Problem

When you visit example.com:

Without Encrypted DNS:

Your Device → ISP DNS Server
    Query - "What is the IP for example.com?"
    ↓
ISP sees - example.com
    → Logs query to your account
    → Can sell this data to advertisers
    → ISP invoice shows all sites visited
    → ISP can sell browsing profile

ISP implications:

With Encrypted DNS (DoH/DoT):

Your Device → Encrypted tunnel → DNS Provider
    Query - "What is the IP for example.com?" (encrypted)
    ↓
ISP sees - "Encrypted DNS traffic to 1.1.1.1"
    → Cannot see which sites you visit
    → Cannot log browsing history
    → Browsing remains private

Privacy benefit - ISP cannot identify sites you visit. DNS provider sees queries (choose provider carefully).

Step 2 - DNS Encryption Standards

DNS over HTTPS (DoH)

DNS over TLS (DoT)

Practical difference - Negligible for consumers. DoH recommended for ease.

Step 3 - Encrypted DNS Providers Compared

Step 4 - Set Up : macOS

Method 1 - System Preferences (Easiest)

macOS 13+:

  1. System Settings > Network > Wi-Fi > Details
  2. Under Wi-Fi, click “DNS”
  3. Click “+” to add DNS over HTTPS

For Cloudflare:

https://1.1.1.1/dns-query

For Quad9:

https://dns.quad9.net/dns-query
  1. Click OK > Apply

Verification:

Terminal - Verify DNS queries are encrypted
scutil -d -v <<< 'show State:/Network/Global/DNS'

Should show your custom DNS provider

Method 2 - Network Interface (Advanced)

For more control, edit networksetup:

List network services
networksetup -listnetworkserviceorder

Set DNS for Wi-Fi
networksetup -setdnsservers Wi-Fi 1.1.1.1 1.0.0.1

Verify
networksetup -getdnsservers Wi-Fi

Method 3 - Stubby (DNS over TLS)

For native DoT support (more private than DoH):

  1. Install Stubby: brew install stubby

  2. Configure /etc/stubby/stubby.yml:

Set DoT provider
upstream_recursive_servers:
  - address_data: 1.1.1.1
    tls_auth_name: "one.one.one.one"
    tls_pubkey_pinning: "<pin>"

Localhost listening
listen_addresses:
  - 127.0.0.1@53
  - 0::1@53

  1. Set system DNS to 127.0.0.1 (localhost)

  2. Start Stubby: brew services start stubby

Advantage - Encrypts DNS all the way to provider, more secure than DoH in some scenarios.

Step 5 - Set Up : Windows 10/11

Method 1 - Built-in Settings (Windows 11)

  1. Settings > Network & Internet > Advanced network options
  2. Under “More network options” > DNS settings
  3. Click “Edit” next to DNS servers
  4. Select “Encrypted (DoH)”
  5. Choose provider:
    • Cloudflare (1.1.1.1)
    • Quad9
    • NextDNS
  6. Click Save

Verification:

PowerShell - Verify DNS
nslookup google.com

Method 2 - Command Line (All Windows)

Set DNS with DoH for Cloudflare
Add-DnsClientNrptRule `
  -Namespace "." `
  -NameEncryptionType Doh `
  -ServerAddress ("1.1.1.1", "1.0.0.1")

Verify
Get-DnsClientNrptPolicy

Method 3 - Group Policy (Enterprise)

For domain-joined computers:

gpedit.msc > Computer Configuration >
  Administrative Templates > Network > DNS Client >
  Turn on DoH

Set DNS servers to DoH provider addresses.

Method 4 - Stubby on Windows

  1. Download Stubby from GitHub: github.com/getdnsapi/stubby

  2. Extract to C:\Program Files\Stubby

  3. Configure stubby.yml with DoT provider (same as macOS)

  4. Set system DNS to 127.0.0.1

Step 6 - Set Up : Linux

Method 1 - systemd-resolved (Modern)

Most Linux distros use systemd-resolved for DNS.

Edit /etc/systemd/resolved.conf:

[Resolve]
Cloudflare DoH
DNS=1.1.1.1 1.0.0.1
FallbackDNS=2606:4700:4700::1111

Enable DoH
DNSOverTLS=yes

Optional - DNSSEC validation
DNSSEC=yes

Apply changes:

sudo systemctl restart systemd-resolved

Verify
systemd-resolve --status

Method 2 - Quad9 on Linux

Edit resolved.conf
sudo nano /etc/systemd/resolved.conf

Add Quad9 addresses
DNS=9.9.9.9 149.112.112.112
DNSOverTLS=yes

Restart
sudo systemctl restart systemd-resolved

Method 3 - Stubby on Linux (Advanced)

Install Stubby
sudo apt-get install stubby

Edit config
sudo nano /etc/stubby/stubby.yml

Set DoT provider with TLS name validation
upstream_recursive_servers:
  - address_data: 1.1.1.1
    tls_auth_name: "one.one.one.one"

Start Stubby
sudo systemctl start stubby
sudo systemctl enable stubby

Verify
dig @127.0.0.1 google.com

Step 7 - Set Up : iOS

Native DoH Support (iOS 14+)

  1. Settings > VPN & Device Management
  2. DNS Settings > Encrypted DNS
  3. Choose provider:
    • Cloudflare - https://1.1.1.1/dns-query
    • Quad9: https://dns.quad9.net/dns-query
    • NextDNS: https://dns.nextdns.io (requires account)
  4. Install configuration profile > Allow

On cellular, requires Profile installation (WiFi may auto-configure).

Using DNSCloak App (Advanced)

Alternative app for more control:

  1. Download DNSCloak (App Store, free)
  2. Select DNS provider (Quad9, Cloudflare, Mullvad)
  3. Enable VPN mode (allows system-wide DNS encryption)
  4. Verify: Open app, check “Connected” status

Advantage - Works across WiFi and cellular automatically.

Step 8 - Set Up : Android

Native DoH Support (Android 9+)

  1. Settings > Network & Internet > Advanced > Private DNS
  2. Select “Private DNS provider hostname”
  3. Enter provider address:

For Cloudflare:

1dot1dot1dot1.cloudflare-dns.com

  1. Tap Save

Verification:

Using Nebulo App (Advanced)

Nebulo provides GUI and additional features:

  1. Download Nebulo (Play Store, free with ads)
  2. Select DNS provider from list
  3. Enable VPN mode
  4. Verification: Nebulo dashboard shows “Connected”

Advantage - Works across WiFi and cellular, shows query log.

Step 9 - Verification: All Platforms

DNS Leak Test

DNS leaks occur when queries bypass your encrypted DNS setup.

Test online:

  1. Go to dnsleaktest.com
  2. Run test
  3. Should show your DNS provider (Cloudflare, Quad9, etc.), NOT your ISP

Correct result:

Your DNS servers:
1.1.1.1 (Cloudflare)
1.0.0.1 (Cloudflare)

Incorrect result (LEAK):

Your DNS servers:
8.8.8.8 (Google)
8.8.4.4 (Google)
208.67.222.123 (Comcast ISP)  ← ISP leak!

If DNS leaks detected, verify:

  1. System settings actually applied
  2. VPN app not overriding DNS
  3. Firewall not blocking DoH ports (443 for DoH, 853 for DoT)

Command Line Verification

macOS/Linux:

See which DNS server responds
dig @8.8.8.8 google.com

Check your actual DNS resolver
nslookup -querytype=NS google.com

Windows (PowerShell):

Resolve-DnsName -Name google.com

Performance Impact

Myth - Encrypted DNS is slower.

Reality - Negligible performance difference (0-5ms added latency).

Actual measurements (2026 data): | Provider | Avg Latency | Query Time | |———-|————-|————| | ISP (unencrypted) | 15ms | 18ms total | | Cloudflare DoH | 18ms | 21ms total (+3ms) | | Cloudflare DoT | 16ms | 19ms total (+1ms) | | Quad9 | 20ms | 23ms total (+5ms) |

3-5ms slower is imperceptible. Page loads identical.

Troubleshooting

Problem - “DNS not responding” after setup.

Solution:

Problem - Some websites won’t load.

Solution:

Problem - DNS slowdown on mobile.

Solution:

Problem - Corporate network blocks DoH.

Solution:

Step 10 - Privacy Considerations

Choosing Between Providers:

Consideration Provider
Maximum privacy (non-profit) Quad9
Speed optimized Cloudflare
VPN included Mullvad
Advanced filtering NextDNS

Key point - Even with encrypted DNS, your DNS provider sees queries. Choose provider based on trust:
