Owners of Xiaomi, Redmi and POCO smartphones often encounter a mysterious option in their connection settings called Private DNS or Private DNS. Many users ignore this option, leaving it as “Auto” without even knowing how powerful it hides. In fact, it is the gateway through which all your domain name requests go, and its correct configuration can dramatically change the quality of the Internet connection.
Change of the standard DNS-The server allows not only to speed up the response of pages, but also to hide the history of visited resources from the Internet provider. MIUI And HyperOS is built into the Android kernel, making it available without installing third-party apps. Understanding how this feature works opens up access to safer, faster web surfing.
In this article, we will take a look at how a private DNS server works, why it should be set up manually, and what addresses are the most reliable today, and how to bypass the simplest ISP locks and protect against malware using only the system capabilities of your device, which is not just a technical setup, but a basic element of digital hygiene of a modern smartphone.
DNS and the role of Private DNS in Android
To understand the importance of setting up, you need to understand the basic mechanism of the Internet. When you type in a site address like mi.com, your device doesn't know where the server is physically located. It sends a request. DNS-server that translates a name into a digital IP-address, such as 192.168.1.1. By default, your smartphone uses DNS-servers automatically provided by a mobile provider or Wi-Fi router.
The problem with standard ISP servers is that they are slow, unencrypted, and censorable. The provider sees all your requests and can redirect you to advertising pages or block access to certain resources. Private DNS (DNS over TLS) solves these problems by forcibly encrypting all traffic requests between the phone and the server selected.
⚠️ Attention: Use of private DNS-The main data traffic (page content, videos, files) remains unencrypted if the site does not use the protocol. HTTPS.
Unlike the old methods of change. DNS, Which required superuser rights or configuring each Wi-Fi connection separately, a modern approach in Android 9 And above, you can set a global rule, which means you're on a home network, in a cafe, or on a mobile Internet. 4G/5G, Your requests will always be sent through the secure channel of the selected provider.
Technically, this is done through the protocol. DNS over TLS. It creates a protected tunnel, preventing substitution. DNS-And the intermediaries are listening to you, and this is especially true for Xiaomi owners, because it's a system that's very important. MIUI It has many background processes actively interacting with servers, and their traffic also becomes hidden from prying eyes.

Advantages of using alternatives DNS-server
Switching to third-party DNS-There are a number of tangible benefits that even an inexperienced user will notice, especially in terms of response speed. Public servers from giants like Google or Cloudflare often handle requests faster than local nodes of small providers, which speeds up the loading of “heavy” sites.
The second important aspect is security. DNS They offer built-in filtering of software and phishing sites, and if you try to go to a dangerous resource, the server will not give it away. IP-This is the first line of defense for the entire system.
- 🚀 Accelerating Download: Decreasing ping and faster domain resolution, especially in gaming and streaming.
- 🛡️ Privacy protection: Your ISP can’t see which websites you visit because requests are encrypted.
- 🚫 Advertising Blocking: Specialized DNS-servers can cut off requests to ad trackers even before the ad loads in the app or browser.
In addition, the use of reliable DNS It helps to bypass simple blockings set by the provider at the domain name level, if the site is blocked only by DNS, Changing the server to a foreign one often allows you to access it without using complex servers. VPN-protocols that can cut speed.
Popular Private DNS providers for Xiaomi
Choosing the right provider is key. Not all servers are equally useful: some are geared toward speed, others are focused on privacy, and others are focused on content filtering. For Xiaomi devices that are heavily using system services and shell advertising, servers with a blocker function are often the best choice.
One of the most popular solutions is AdGuard DNS, which specializes in blocking ads and trackers at the network level. When you use it, you may notice that ads disappear not only in the browser, but also in some applications and games where they are loaded dynamically.
For those who care about speed and stability, Cloudflare or Google servers are ideal, with huge infrastructure and minimal response times. Cloudflare also claims a strict privacy policy, claiming it does not store user logs or sell data to advertisers.
| Provider | Server address (Hostname) | Substantive function | Speed. |
|---|---|---|---|
| Google Public DNS | dns.google | Stability and speed | Tall. |
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com | Privacy and speed | Very high. |
| AdGuard DNS | dns.adguard.com | Blocking ads | Medium/High |
| Quad9 | dns.quad9.net | Security (Malware) | Tall. |
There are specialized servers, like Quad9, that focus solely on security by blocking access to known malicious domains, and the choice depends on your priorities: if you're annoyed by ads on Xiaomi, choose AdGuard. If you want maximum network responsiveness, Cloudflare.
💡
When choosing an AdGuard server, use the address dns.adguard.com to block ads. There are also family versions with adult content filtering, but they require a separate search for current hosts.
Step-by-step instructions for setting up Private DNS
Setup private DNS on Xiaomi, Redmi and POCO smartphones is done through the standard Android settings menu. The interface may vary slightly depending on the version of MIUI or HyperOS, but the logic remains the same. You do not need root rights or install additional software.
To start, open the Settings menu and go to Connect and Sharing (or just Connection).Look for Private DNS. In some firmware versions, it may be in advanced Wi-Fi settings or in Security and Privacy.
☑️ Checking before setting up
The default is Auto or Disconnected, and you have to select Host Name of the Provider. DNS» (Or "manually"). This is where the server address is entered. Be careful: it's the domain name you type in, not the domain name. IP-address, as the protocol is private DNS Domainwork.
dns.googleAfter entering an address, such as dns.google or dns.adguard.com, click Save.The system will check the server's availability. If the address is entered correctly and the server is available, a connection notification will appear at the top of the screen, and a DNS icon may appear in the status bar.
⚠️ Note: Do not use prefixes when entering an address http:// or https://, Do not add ports (for example,:53 or:853). Enter only a clean domain name, otherwise the system will give a connection error.
If you have received a message “Disconnected” after saving, or the Internet is lost, then the address was entered with an error or the selected server is blocked by your ISP, in which case try the alternative option from the list above or return the setting to the “Auto” position.
Diagnosis of problems and possible errors
Despite the ease of customization, users may face problems, the most common of which is the complete or partial disappearance of the Internet. DNS-The server is not available in your region or blocked by the carrier, in which case the smartphone can not resolve domains, and the applications stop working.
Another common problem is local area network conflict: some corporate networks or public Wi-Fi (airports, hotels) require authorization through a portal page, and if you have Private DNS enabled, this page may not load because the request is redirected to an external server, in which case the function has to be temporarily disabled.
- 📉 Speed reduction: If the server is geographically far away, response times may increase and sites may open more slowly.
- 🔒 Blocking legitimate resources: Aggressive filters (like AdGuard) can break the layout of some sites or interfere with the work of banking applications.
- 📡 Connection Instability: When a mobile network signal is poor, encryption DNS-Requests can add delays, leading to timeouts.
You can use commands in the terminal or special analysis applications to diagnose, but the easiest way is to compare the speed of opening sites before and after changing settings. It is also useful to periodically check whether protection works on specialized test sites.
💡
If the Internet is lost after setting up Private DNS, first return the setting to Auto or Disconnected mode to restore access, and then try another server.
The Impact of DNS on Autonomy and Battery
The impact of a DNS change on battery life is a common concern for Xiaomi users. Theoretically, using an encrypted channel (TLS) requires additional processing resources to shake hands and encrypt queries. However, on modern smartphones with Snapdragon or MediaTek processors, this load is negligible.
Moreover, the use of fast DNS-And servers can even extend the life of the battery. Why? Because the communication module gets a response from the server faster and goes into standby mode, less time being active in the search for a signal or downloading data. Domain resolution errors that lead to repeated connection attempts, on the contrary, land the battery faster.
So for Xiaomi owners, switching to an optimized DNS is likely to have a positive impact on power consumption, especially in the context of unstable network coverage, where the phone is constantly trying to reconnect.
It’s worth noting that some of Xiaomi’s smart features, such as browser preloading or Mi back-end synchronization, also benefit from a stable and fast DNS. This makes the system more responsive overall, without requiring a battery-less casualty by the evening.
