Why Change Your DNS Service Anyway?

Most of us connect to the internet without a second thought for how our online destinations are actually reached. Domain Name System (DNS) services translate website names into the IP addresses your devices use to communicate; by default, you’re almost always using your ISP’s DNS service. While functional, these default DNS services collect a fair amount of data about your browsing habits. This data is often used for ad targeting, tracking, and can even be leveraged to redirect your searches or restrict access to certain content. Changing your DNS provider can mitigate these privacy issues, but using an unencrypted DNS service means your queries are still visible to your ISP or anyone else snooping on your network.

Enter encrypted DNS protocols like DNS over HTTPS (DoH) or DNS over TLS (DoT), which help shield your DNS queries from prying eyes. However, not every DNS service supports these protocols, and some require more complex setup—here’s where NextDNS shines, offering powerful privacy features, content filtering, and customizable settings while supporting modern encryption standards.

The Standout Features of NextDNS

• Privacy-First Policy: NextDNS maintains a straightforward logging policy. If something isn’t essential, it doesn’t get stored. This least-log approach means your browsing data isn’t being harvested or shared.
• Powerful Content Filtering: Easily block adult content, trackers, malicious sites, or even specific apps and sites like Facebook, Fortnite, or Tinder. Built-in SafeSearch and YouTube Restricted Mode provide family-friendly browsing by default.
• Flexible Setup: Whether you use a single device, several computers, or want whole-home protection via your router, NextDNS supports it all. Their platform is particularly praised for its iOS and Android compatibility, overcoming the restrictions that typically limit DNS customization on mobile devices.
• Custom Profiles for Every Need: Assign DNS filtering rules, block or allowlist, and restrictions based on device, subnet, MAC address, or even the current network user—perfect for families and small organizations.
• Open Platform and Community Support: With a generous free tier (up to 300,000 DNS queries monthly across unlimited devices) and a strong, supportive online community, getting help or troubleshooting is easy.

Getting Started: Creating a NextDNS Account

While you can use NextDNS without signing up, creating a free account unlocks advanced customization and tracking features. After registration, you receive a unique Profile ID, which is essential for tailoring settings and managing devices. Your account dashboard displays the DNS server addresses specific to your profile and provides setup guides for nearly every platform. Keep your Profile ID handy, as it’s required in some setup methods.

Device-by-Device: How to Install and Configure NextDNS

NextDNS can be activated in a variety of ways, and the best approach depends on your devices and goals. Below, you’ll find step-by-step instructions for the most common installation scenarios.

1. Setting Up NextDNS on Your Home Router

The most comprehensive way to protect and filter all traffic in your household is by configuring NextDNS directly on your router. This means every device connected to your Wi-Fi will benefit from DNS protection automatically. However, keep in mind that some advanced device identification and per-device settings may require more granular setup.

1. Access Your Router’s Admin Panel: Usually, you can do this by entering your router’s IP address (often 192.168.1.1 or 192.168.0.1) into your browser. Check the label on your router for login information.
2. Find the DNS Server Settings: This is commonly located in the “Internet” or “LAN” section of the administration panel.
3. Enter the NextDNS DNS Server Addresses:
   
   • Primary DNS: 45.90.28.232
   • Secondary DNS: 45.90.30.232
   These are the default addresses, but you may be given unique DNS addresses tied to your profile for extra security and filtered access.
4. Save & Restart: Be sure to save changes, then restart your router if necessary to apply new settings to all devices.

Note: Some advanced routers or mesh systems (e.g., Google Wifi, Ubiquiti’s UniFi Dream Machine Pro) may require firmware updates or have slightly different DNS settings. If needed, consult your router manufacturer or seek NextDNS’s dedicated setup guides.

2. NextDNS on Individual Devices

Windows and macOS

Setting NextDNS system-wide on a desktop or laptop often means simply updating your DNS settings, but for maximum privacy (and to use encrypted DoH/DoT), it’s best to use the NextDNS CLI app. This also enables advanced features like device identification and per-user filtering.

1. Download the CLI Client: Visit NextDNS’s official GitHub Wiki for platform-specific instructions and download links.
2. Install the Client: Follow the on-screen prompts or terminal instructions. You may need administrative privileges.
3. Configure with Your Profile ID: When prompted, enter your NextDNS Profile ID to link the device with your dashboard settings.
4. Control and Monitor: After install, use terminal commands to start, stop, restart, or monitor the service. Typical commands include nextdns start, nextdns stop, etc.
5. Update or Remove: The same install command can be used to update or uninstall the client as needed.

The CLI client supports numerous advanced options, including automatic LAN client identification, integration with various routers, cache controls, and conditional forwarding based on domain or user.

iPhone & iPad (iOS Devices)

While Apple makes DNS customization tricky on iOS, NextDNS offers a streamlined process by providing downloadable configuration profiles (“.mobileconfig”). These profiles let you set up encrypted DNS with just a few taps.

1. Go to your NextDNS dashboard on a Safari browser on your device.
2. Download your personalized .mobileconfig file linked to your Profile ID.
3. Install the profile; you’ll be guided through the device’s built-in configuration screens.
4. For managed (supervised or company-owned) devices, use a Mobile Device Manager (MDM) or Apple Configurator to distribute the profile.

After installation, all DNS queries from your device are filtered and encrypted according to your settings. You can remove the profile at any time via Settings if needed.

Android Devices

Android’s “Private DNS” feature (supported on Android 9 Pie and later) makes switching to NextDNS straightforward. Simply update the DNS-over-TLS setting:

1. Open: Settings > Network & Internet > Advanced > Private DNS.
2. Choose: “Private DNS provider hostname”.
3. Enter: dns.nextdns.io (you may use a more specific URL tied to your profile if shown in your dashboard).
4. Save and exit. Your DNS queries are now encrypted and filtered.

For enterprise-managed devices, these settings can also be pushed remotely via your MDM system.

Raspberry Pi or Linux Devices

For those running Pi-hole or similar solutions, NextDNS can function as the DNS backend or as a standalone DNS filter. Installation is usually handled via the CLI client:

1. SSH into your Pi or Linux device.
2. Run the install script from GitHub (see official NextDNS documentation).
3. Follow instructions to link with your Profile ID and configure desired options.
4. Set your Pi’s (or server’s) IP address as the DNS server for the rest of your network, typically via your home router settings.

This solution is popular for those seeking local performance benefits, detailed analytics, and robust, network-wide filtering capabilities.
