NextDNS Review & Setup Guide: The Ultimate Guide to DNS-Level Security and Control

Introduction: Taking Control of Your Internet Experience with NextDNS

In today’s hyper-connected world, we rely on the internet for almost everything: work, communication, entertainment, and education. However, this reliance also exposes us to a multitude of online threats, including malware, phishing attacks, intrusive trackers, and unwanted advertisements. While traditional security measures like antivirus software and firewalls are essential, they often don’t address the fundamental level at which your devices connect to the internet: the Domain Name System (DNS).

DNS is essentially the phonebook of the internet. When you type a website address (like google.com) into your browser, your device contacts a DNS server to translate that human-readable address into a numerical IP address (like 172.217.160.142) that computers use to communicate. Most people use the default DNS servers provided by their Internet Service Provider (ISP), which are often slow, unreliable, and don’t offer any security or privacy features.

This is where NextDNS comes in. NextDNS is a cloud-based, customizable DNS service that acts as a powerful first line of defense against online threats, provides granular control over your internet traffic, and can even improve your browsing speed. It’s like having a highly configurable firewall and content filter built directly into your internet connection. Instead of just blindly resolving domain names, NextDNS allows you to define rules, block malicious domains, filter content, and analyze your DNS traffic, giving you unprecedented control over your online experience.

This comprehensive guide will delve into every aspect of NextDNS, providing a thorough review of its features, benefits, and potential drawbacks. We’ll then walk you through the setup process on various devices and platforms, offering tips and best practices to optimize your configuration.

2.2.5 Router (Recommended for Whole-Network Protection)

Configuring NextDNS on your router is the best way to protect all devices on your home network. The specific steps vary depending on your router model, but the general process is as follows:

Access your router’s administration interface: This is usually done by entering your router’s IP address (often 192.168.1.1 or 192.168.0.1) into a web browser. You’ll need your router’s username and password.
Find the DNS settings: The location of the DNS settings varies by router. Look for options like “WAN Settings,” “Internet Settings,” “DHCP Settings,” or “DNS Settings.”
Enter the NextDNS IPv4 and IPv6 addresses: Replace the default DNS server addresses with the NextDNS addresses from your Setup tab.
(Optional) Configure DDNS: If your home IP address is dynamic, set up a dynamic DNS (DDNS) updater on your router (or using a separate service) and link it to your NextDNS configuration (in the “Linked IP” section of the Setup tab). This ensures that NextDNS always knows your current IP address. NextDNS provides instructions for various DDNS providers.
Save the changes and reboot your router: This will apply the new DNS settings to all devices connected to your network.
(Optional, but highly recommended) Configure Router to use DoH/DoT: Many modern routers support encrypted DNS protocols like DoH and DoT. If your router supports it, configure it to use the DoH/DoT address from your NextDNS setup page. This encrypts the DNS communication between your router and NextDNS, providing an extra layer of security.
(Optional) Block Alternate DNS: To ensure devices on your network can’t bypass NextDNS by manually configuring their own DNS settings, you may want to block access to other DNS servers. This can often be done in your router’s firewall settings by blocking outbound traffic on port 53 (standard DNS port) except for traffic destined to your NextDNS server IPs. Be careful with this setting, as incorrect configuration can disrupt your internet access.

2.2.6 Linux

systemd-resolved (Common on modern distributions):
1. Edit the resolved.conf file: sudo nano /etc/systemd/resolved.conf
2. Under the [Resolve] section, add the following lines, replacing your-nextdns-doh-address with your unique DoH address from the NextDNS Setup tab:
  DNS=your-nextdns-doh-address DNSOverTLS=yes
3. Save the file and restart the systemd-resolved service: sudo systemctl restart systemd-resolved
NetworkManager (Common on desktop environments):
1. Open your network connection settings.
2. Edit your active connection (Wi-Fi or Ethernet).
3. Go to the IPv4 and IPv6 tabs.
4. Change the Method to “Automatic (DHCP) addresses only” or “Manual”.
5. Enter the NextDNS IPv4 and/or IPv6 addresses in the DNS servers field.
6. Save the changes.
7. For DoH/DoT, you may need to use a command-line tool like nmcli to configure it, as the GUI may not fully support it. Refer to the NetworkManager documentation for details.
Other DNS Clients (e.g., dnsmasq, unbound): If you’re using a different DNS client, consult its documentation for instructions on how to configure custom DNS servers and enable DNS encryption.

2.3 Testing Your NextDNS Setup

After configuring NextDNS, it’s crucial to test that it’s working correctly:

Visit the NextDNS Setup page: The Setup tab in your NextDNS dashboard should indicate that you are using NextDNS. It will show a green checkmark if everything is configured correctly.
Visit a test website: NextDNS provides a test website (linked on the Setup page) that will show you if your DNS queries are being routed through NextDNS and if various security features are enabled.
Check your logs: If you’ve enabled logging, check your NextDNS logs to see your DNS queries and any blocked requests.
Try accessing a blocked website: If you’ve configured a blocklist or parental control rule, try accessing a website that should be blocked. If NextDNS is working correctly, you should see a block page.
Use a DNS leak test: Websites like https://www.dnsleaktest.com/ can help you verify that your DNS queries are not leaking to your ISP or other third parties.

Part 3: Advanced Configuration and Best Practices

3.1 Optimizing Blocklists and Allowlists

Start with a balanced approach: Don’t enable every blocklist available. Start with a recommended combination like “NextDNS Ads & Trackers Blocklist” and “OISD.” Monitor your logs and adjust as needed.
Use the Allowlist strategically: If you encounter false positives (legitimate websites being blocked), add them to your Allowlist.
Regularly review your logs: Identify any frequently blocked domains that shouldn’t be blocked and add them to your Allowlist. Also, look for any suspicious domains that are not being blocked and consider adding them to your Denylist.
Consider using more aggressive blocklists (with caution): If you want maximum ad and tracker blocking, you can experiment with more aggressive blocklists like “1Hosts (Pro).” Be prepared for potential false positives and be diligent about using your Allowlist.
Use community-maintained blocklists: Explore the wide range of community-maintained blocklists available in NextDNS. These lists often focus on specific areas (e.g., regional ads, social media trackers) and can be useful for fine-tuning your blocking.

3.2 Leveraging Parental Controls Effectively

Customize categories: Don’t rely solely on the default category settings. Review each category and customize it to match your family’s needs and values.
Use Recreation Time: Implement time limits for specific categories or websites to manage screen time and encourage healthy online habits.
Enforce Safe Search: Enable safe search on all relevant search engines and platforms.
Block Bypass Methods: Prevent children from circumventing parental controls by blocking access to VPNs, proxies, and alternative DNS services. This is a crucial step for effective parental control.
Communicate with your children: Explain the reasons for using parental controls and discuss online safety and responsible internet use.

3.3 Utilizing Profiles for Different Devices and Networks

Create separate profiles for different users or devices: For example, create a “Kids” profile with strict parental controls, a “Work” profile with fewer restrictions, and a “Guest” profile for visitors.
Apply profiles based on network: If your router supports it, you can apply different NextDNS profiles to different Wi-Fi networks (e.g., a separate guest Wi-Fi network with its own profile).
Use device-specific configurations: The NextDNS apps for Windows, macOS, iOS, and Android allow you to apply different profiles to individual devices.

3.4 Understanding and Using DNS Rewrites

Create custom shortcuts: Rewrite a short, easy-to-remember domain name to a longer, more complex URL.
Access local network resources: Rewrite a domain name to the IP address of a device on your local network (e.g., a NAS server, a printer).
Block specific subdomains: Rewrite a subdomain to a non-existent IP address to effectively block it.

3.5 Monitoring Logs and Analytics

Regularly review your DNS logs: Identify potential threats, track blocked requests, and fine-tune your blocklists and allowlists.
Use the analytics dashboard: Gain insights into your overall DNS traffic, top blocked domains, and security threats.
Pay attention to device-specific data: If you’ve configured device-specific settings, monitor the DNS activity of individual devices to identify any unusual behavior.

3.6 Staying Updated

Keep your NextDNS apps and router firmware updated: Updates often include security patches and performance improvements.
Monitor the NextDNS blog and community forums: Stay informed about new features, best practices, and potential issues.
Review your configuration periodically: As your needs and the online threat landscape evolve, revisit your NextDNS settings to ensure they are still optimal.
