We’ve all been there: you’re trying to read an article or play a mobile game, and you are absolutely bombarded by pop-ups, banners, and auto-playing video ads.
While you can install ad-blocking extensions on desktop browsers, mobile devices are notoriously tricky. But what if you could block ads, trackers, and malicious domains across your entire phone—inside apps, games, and browsers—without downloading a single app or draining your battery?
Enter AdGuard DNS. By changing just one simple setting on your phone, you can route your web requests through a secure, ad-filtering server.
Here is everything you need to know about how it works, the pros and cons, and how to set it up in under two minutes.

What is AdGuard DNS?
Whenever you visit a website (like google.com), your phone uses a Domain Name System (DNS) to translate that human-readable name into a computer-friendly IP address. Normally, this lookup is handled automatically by your mobile carrier or public Wi-Fi provider.
AdGuard DNS replaces your provider's default directory. When a game or website tries to load an ad or a tracker, AdGuard simply refuses to look up that specific domain, blocking the ad before it even has a chance to download to your device.
The Pros: Why You Should Try It
Zero Battery or RAM Drain: Traditional ad-blocking apps run constantly in the background, hogging your device's memory and draining the battery. Because AdGuard DNS is configured natively in your phone’s operating system settings, it uses absolutely no extra resources.
System-Wide Protection: It doesn’t just clean up your mobile web browser; it blocks trackers and advertisements inside your apps and games too.
Encrypted Privacy (DNS-over-TLS): Standard DNS requests are sent in plain text, meaning your mobile provider or a dodgy café Wi-Fi host can spy on the sites you visit. Configuring a "Private DNS" encrypts these queries, keeping your browsing habits private.
A Strict No-Logs Policy: AdGuard has a highly transparent privacy policy. For their public DNS service, they do not log your IP address or track the domains you visit.
The Cons: The Trade-offs to Keep in Mind
As brilliant as this method is, it is not without a few minor quirks:
An "All-or-Nothing" Approach: Because there is no app interface to quickly toggle on and off, you can't easily "pause" the blocking if a website breaks. If a retail link (like a sponsored Google Shopping search result) won't open, you have to dig back into your system settings to turn the Private DNS off temporarily.
Blank Spaces on Webpages: AdGuard DNS stops ad content from loading, but it cannot rewrite the code of the webpage you are viewing. You may occasionally see empty grey boxes or awkward blank spaces where an ad was supposed to sit.
It Can't Block First-Party Ads: Because it blocks ads at the domain level, it cannot stop ads that are served directly from the same servers as the content. This means ads on platforms like YouTube, Instagram, and TikTok will still get through.
How to Set It Up
To get started, you just need to choose which server profile suits your needs:
| Profile Mode | Hostname to Copy/Paste | Best For |
| Default (Standard) | dns.adguard-dns.com | Standard ad, tracker, and malware blocking. |
| Family Protection | family.adguard-dns.com | Blocks ads, blocks adult content, and forces SafeSearch. |
On Android (Android 9 and newer)
Open your phone's Settings and go to Network & Internet (sometimes called Connections).
Tap Private DNS (this is often located under "Advanced" or "More connection settings").
Select Private DNS provider hostname.
Paste your chosen hostname (e.g.,
dns.adguard-dns.com) and tap Save.
On iOS (iPhone & iPad)
Apple does not allow you to manually type in a custom DNS hostname directly within the native iOS settings. Instead, you have to use a lightweight configuration profile:
Head to the official AdGuard DNS Setup Page.
Select iOS and download their official configuration profile.
Open your iPhone's Settings, tap Profile Downloaded at the top of the screen, and follow the prompts to install it.
(Note: While you may see older guides referencing dns.adguard.com, the official and updated hostname to use is dns.adguard-dns.com.)
The Verdict: If you want a free, set-and-forget way to make your mobile browsing cleaner, faster, and significantly more private, setting up AdGuard DNS is an absolute no-brainer.
