AdGuard DNS: 7 Essential Features I Tested

AdGuard DNS is a privacy-focused DNS resolver that can block requests to advertising, tracking, phishing, scam, and malicious domains before your device connects to them. That sounds simple, but the useful part is where the filtering happens: at the DNS layer. Instead of relying on one browser extension, you can apply filtering to phones, computers, apps, smart TVs, game consoles, and even an entire home network.

My goal with this AdGuard DNS test is practical: see where the resolver adds value, how it behaves beside a VPN, and where browser or endpoint protection still has a job. DNS filtering can stop a connection to a listed domain, but it cannot inspect every file, hide your public IP address, or surgically remove every ad from a webpage.

I focus on seven useful features: network-level filtering, public resolvers, encrypted DNS, private rules, security filtering, parental controls, and device support. If you are asking what is AdGuard DNS, is AdGuard DNS safe, or whether paid service adds enough over AdGuard DNS free, the table gives you the short version.

What I checked	Why it matters	What to remember
Filtering	Blocks many ad, tracker, phishing, and malicious-domain requests	DNS cannot remove every first-party ad or page element
Privacy and control	Encrypted DNS, custom rules, device visibility, and query tools	Your DNS provider still processes DNS requests
Network use	Works on individual devices or at router level	Browsers and VPNs can override router DNS settings

Key Takeaways

• AdGuard DNS works at the domain-resolution layer, so filtering can reach apps and devices that cannot run a traditional browser extension.
• The public service is quick to configure, while Private DNS adds device profiles, custom rules, blocklists, statistics, and a query log.
• The standard public AdGuard DNS IP addresses are useful for routers and devices that only accept manual IPv4 or IPv6 DNS values.
• Encrypted protocols such as DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC help protect DNS traffic in transit.
• The service can block known phishing and malicious domains, but it does not scan downloaded files or replace endpoint protection.
• AdGuard DNS free is enough to learn the platform; paid Personal is mainly about more capacity and room for a larger household setup.
• The best results come from treating DNS filtering as one layer beside browser security, software updates, VPN routing where appropriate, and sensible network separation.

What Is AdGuard DNS and How Does an AdGuard DNS Server Work?

To answer what is AdGuard DNS, start with ordinary DNS. When you type a domain name, your device asks a resolver which IP address belongs to that name. A filtering resolver checks the requested domain against rules before returning an answer. If the domain matches an advertising, tracking, phishing, scam, or malicious-domain rule, the resolver can refuse or modify the response instead of sending your device toward the unwanted destination.

The resolver makes that decision before the browser or app connects to the requested host. That is why the same filtering concept can work outside the browser on televisions, mobile apps, consoles, and smart devices.

HackersGhost Note: I think of DNS filtering as a receptionist with a deny list. It can refuse to give you directions to a known bad address. It does not follow you into the building, inspect every room, and confiscate a suspicious ZIP file.

Public AdGuard DNS Server Options

The public service has three profiles. Default blocks ads and trackers; Family adds adult-content blocking plus Safe Search and restricted modes where supported; Non-filtering resolves domains without those filtering rules. I like having a clean non-filtering option for troubleshooting.

If a device only accepts numeric values, the standard public AdGuard DNS IP pair for default filtering is 94.140.14.14 and 94.140.15.15. Family and non-filtering profiles use different addresses. I still verify current values before changing a router; infrastructure details deserve fewer assumptions than pub-quiz answers.

7 Essential AdGuard DNS Features I Tested

1. AdGuard DNS Ad Blocker Filtering Across Devices

The first feature is the one most people arrive for: domain-level blocking. The phrase AdGuard DNS ad blocker is convenient, but it needs context. This is not the same type of blocker as a browser extension that can inspect a webpage and hide individual elements. DNS filtering blocks requests to known advertising and tracking domains. When an app tries to contact one of those domains, the request can stop before the connection is established.

That wider reach is what interests me. A browser extension protects the browser; DNS can also affect apps, smart TVs, consoles, and devices where installing software is awkward. On a mixed network, one resolver policy can reduce unwanted background connections without touching every device separately.

The limitation is equally important. If an advertisement is delivered from the same domain as the content you actually want, DNS cannot neatly split the two. Blocking the domain may break the page or service. Cosmetic filtering is also outside its job description, so blank spaces can remain where an advertising request was blocked.

2. AdGuard DNS IP and Public Resolver Flexibility

Not every device supports modern encrypted DNS, so plain AdGuard DNS IP values still matter. Routers, televisions, consoles, and older interfaces may expose only preferred and alternate DNS fields, making the public pair the simplest route to filtering.

Default, family, and non-filtering choices also make troubleshooting cleaner. If a site breaks, compare it briefly with the non-filtering resolver instead of disabling every security control at once.

3. Encrypted AdGuard DNS Server Connections

The service supports DNS-over-HTTPS, DNS-over-TLS, and DNS-over-QUIC. With a supported encrypted method, DNS queries are protected in transit between your device and the resolver, so a casual observer on the local network should not see those requests in plain text.

Encryption does not make the resolver blind; the provider still processes the request. If your goal is to hide your public IP address and route traffic elsewhere, you need a VPN rather than a DNS resolver.

HackersGhost Note: “Encrypted” is one of those words that can make a settings page look invincible. I always ask the boring follow-up: encrypted between which two points, and what can each endpoint still see?

4. Private Rules, Blocklists, Statistics, and Query Logs

Private DNS is more interesting than a fixed public resolver because you can connect devices, enable blocklists, create rules, inspect statistics, and review the query log. Statistics include requested domains, blocked requests, categories, destinations, clients, and encrypted-request data.

The query log is especially useful when a legitimate service breaks. I can inspect recent blocks, allow a likely dependency, and test again instead of disabling protection because one checkout page developed feelings.

IP logging is another privacy control I would not enable automatically. AdGuard says it is disabled by default and can be switched on for troubleshooting. If I do not need that detail, I leave unnecessary logging alone.

5. Security Filtering for Phishing and Malicious Domains

Security filtering adds value over a basic resolver. Private DNS can block known malicious, phishing, and scam domains, and it offers security lists plus an option for newly registered domains, which are often abused in short-lived phishing campaigns.

That can stop a connection to a known dangerous destination, but no reputation system catches every new domain instantly and it cannot inspect a file from an allowed host. Attackers can move faster than lists update.

I therefore treat the security side as a valuable extra checkpoint rather than permission to click random links. A resolver can close one door. It cannot stop me from carrying the suspicious package in through another one.

6. Parental Controls Beyond a Simple Family DNS

The public family resolver is the quick option, while Private DNS adds adult-site controls, Safe Search, restricted YouTube behavior, service and category blocking, plus schedules. That is more practical when devices need different rules.

I prefer device-specific policies because a child’s tablet, work laptop, and smart television do not need identical restrictions. Per-device control avoids making the whole network so strict that everyone tries to bypass it.

7. Broad Device Support and Router-Level Deployment

The resolver can be configured on desktop and mobile platforms, Linux, routers, consoles, and smart TVs. Router deployment gives otherwise unmanaged devices a default policy, although VPNs and device-specific encrypted DNS can override it.

My home lab makes that easy to visualize. I use a Cudy WR3000 on a controlled network with Proton VPN over WireGuard and Secure Core. A separate TP-Link Archer C6 is used for sniffing and defensive experiments and is not connected directly to my modem. Those networks serve different purposes, so I do not copy one policy across both blindly.

My second-hand HP EliteBook is upgraded to 32GB of RAM. I chose VMware over VirtualBox and keep Kali Linux and Parrot OS available, with Parrot as my main VM, alongside deliberately vulnerable lab machines. DNS filtering helps, but segmentation matters more than asking a resolver to babysit an intentionally vulnerable system.

Is AdGuard DNS Safe for Everyday Use?

Is AdGuard DNS safe? For normal personal use, I consider it a sensible privacy and security layer when it is configured with realistic expectations. The service supports encrypted DNS, gives private users control over filtering, and lets you inspect or disable logging features depending on what you actually need.

The trust model still matters. Your provider processes the domains you ask it to resolve. Encrypted transport protects the trip to the resolver; it does not remove the resolver from the equation. That is simply how third-party DNS resolution works.

No DNS service is a complete security product. Allowed domains can still serve malicious files, while cookies, fingerprinting, compromised accounts, unsafe extensions, and vulnerable software sit outside DNS control.

HackersGhost Note: My safety rule is simple: I want every security layer to do one job well and tell me where the job ends. AdGuard DNS passes that test better when I treat it as DNS filtering, not as a replacement for the rest of my stack.

AdGuard DNS Free vs Paid: Which One Makes Sense?

AdGuard DNS free actually covers two useful starting points. The public resolver can be used without building a custom filtering policy, while the free Starter account for Private DNS gives you a dashboard and limited private capacity. At the time I checked the plan page, Starter included up to 300,000 monthly requests, five devices, two servers, and 100 rules.

For testing one or two devices, that is enough to understand whether the workflow suits you. The paid Personal plan expands the monthly request allowance, device count, server count, and rule capacity. The value is therefore less about “paid blocks ads while free does nothing” and more about how much control and capacity you need.

For my setup, the private dashboard is the interesting part. Device separation, request visibility, custom rules, and false-positive troubleshooting offer more value than pointing everything at one public resolver.

If you already know you want the Personal plan, this is the second place I would put the offer rather than hiding the commercial link at the very bottom of a long technical article.

AdGuard DNS Ad Blocker: What It Blocks and What It Cannot

The most common misunderstanding around an AdGuard DNS ad blocker is expecting browser-extension behavior. A DNS resolver can block the domain request, but it cannot rewrite HTML, hide leftover containers, or separate two pieces of content arriving from the same hostname.

Ads and trackers from separate domains

This is the sweet spot. Many advertising networks, analytics platforms, telemetry systems, and trackers use dedicated domains. When one of those domains appears on an enabled filter, the connection can be blocked before the remote server receives the request. The same rule can protect multiple apps without each app understanding anything about ad blocking.

First-party advertising and sponsored content

When the ad and wanted content share the same domain, DNS becomes a blunt instrument. Blocking the hostname can break the entire service. This is why some video-platform advertising, sponsored feed content, and first-party promotions are difficult or impossible to remove reliably at DNS level.

Downloaded files and endpoint threats

A DNS block can stop access to a known malicious domain, but it cannot open archives, inspect macros, or quarantine files. Endpoint protection still has its own job. I prefer overlapping checkpoints to asking a resolver to become antivirus with a fake moustache.

AdGuard DNS vs Cloudflare and NextDNS

Standard Cloudflare DNS is best known as a fast public resolver with privacy-focused positioning rather than as a customizable ad-blocking platform. Cloudflare also offers family-oriented resolver options, but the default 1.1.1.1 experience is much simpler than Private AdGuard DNS.

NextDNS is a closer comparison because it also focuses on configurable DNS filtering, analytics, device policies, security lists, and parental controls. If you already use AdGuard products, the AdGuard ecosystem can make the choice feel more coherent. If you enjoy tuning every resolver option like a cockpit panel, both deserve consideration.

I would not choose from a feature checklist alone. Performance depends on geography and routing, while filtering depends on your rules. Configure one device, use normal sites and apps, and judge the balance between control and breakage.

My AdGuard DNS Test Workflow in a Real Home Lab

My AdGuard DNS test is practical. A huge blocked-request counter means little if I cannot explain what was blocked, why it mattered, or whether normal browsing still works.

Step 1: Confirm the resolver path

I first verify that the test device is actually using the intended AdGuard DNS server. This matters more than it sounds. A browser can use its own encrypted resolver, a VPN can push its own DNS, and a router can advertise different settings over DHCP. A beautiful dashboard means very little if the test traffic quietly takes another exit.

Step 2: Use normal sites before creating aggressive rules

I use normal sites before adding extra filters. That creates a baseline, so if a login, payment widget, or embedded service breaks later, I can compare the query log with known-good behavior.

Step 3: Add one custom rule and reverse it

Then I block one harmless test domain, confirm it, and allow it again. Both directions matter. The useful question is whether I can troubleshoot my own rule without spending an evening arguing with DNS cache.

Step 4: Compare device-level and router-level behavior

With my EliteBook and lab routers, I compare device-level encrypted DNS with router DNS. When the Cudy carries Proton VPN WireGuard traffic through Secure Core, I check whether the VPN supplies its own resolver. I do not force another DNS path just to make a dashboard light up; avoiding leaks matters more.

Step 5: Keep vulnerable machines separate

My vulnerable VMs and TP-Link lab segment stay isolated. DNS filtering can reduce contact with known unwanted domains, but it is not segmentation. Routing and network boundaries still contain mistakes that no blocklist can predict.

Common AdGuard DNS Problems and Practical Fixes

A legitimate website stops working

Open the query log and look for recently blocked domains associated with the broken service. Temporarily allow the most likely dependency and reload the page. If it works, you have a useful clue. I prefer one controlled exception over disabling every list and declaring victory.

The dashboard shows no requests

Confirm the device is using the intended profile. A VPN, browser-specific DoH setting, cached network configuration, or different DHCP-provided resolver may be bypassing your private server. Reconnect the network after changing DNS settings and test again.

Ads remain visible after the AdGuard DNS test

That does not automatically mean AdGuard DNS failed. The advertising may be first-party, embedded with wanted content, cached, or delivered from infrastructure that cannot be blocked safely. If precise page cleanup matters, pair DNS filtering with a dedicated content blocker in the browser.

The router setup changes when the VPN connects

Many VPN configurations provide their own DNS resolver to prevent leaks. Check the VPN and router documentation before overriding that behavior. I would rather use the VPN provider’s intended DNS path than accidentally send DNS outside the tunnel just to keep another dashboard populated.

Who Should Use AdGuard DNS?

• People who want domain-level filtering on devices that cannot run browser extensions.
• Households that want different policies for phones, computers, televisions, and children’s devices.
• Home-lab users who value query visibility, custom rules, blocklists, and quick troubleshooting.
• Users who want encrypted DNS without confusing DNS protection with full VPN anonymity.
• People who want a simple AdGuard DNS free starting point before deciding whether private capacity is worth paying for.

It is less suitable as a standalone answer when your main goal is perfect cosmetic ad removal, antivirus-style file scanning, hiding your public IP address, or blocking every advert on large video and social platforms. Those tasks need different controls.

My Verdict: Is AdGuard DNS Worth Using?

Yes, for the right job. The service adds a useful network-level layer for blocking many advertising, tracking, phishing, scam, and malicious-domain requests. The public resolver is easy to try, while Private DNS adds device separation, custom rules, blocklists, statistics, and a query log.

Its strongest advantage is reach. A smart television or app may never support a browser extension, but it still asks DNS where its analytics server lives.

In my setup, I keep DNS filtering beside browser controls, endpoint security, segmentation, and VPN routing where needed. That is more realistic than asking one product to become blocker, antivirus, VPN, firewall, and life coach.

HackersGhost Note: The best security products in my lab are the ones I can explain in one sentence. AdGuard DNS blocks unwanted domain requests and gives me control over the resolver policy. That is a useful job, and it does not need a cape.

If that is the layer missing from your setup, the Personal plan is an easy upgrade path from AdGuard DNS free. This is my third and final affiliate placement in the article, because a useful recommendation should be visible without turning the page into a shopping channel.
