The speed of loading web pages and the stability of the connection on your smartphone often depend not only on the provider, but also on the domain name server used. By default, Android uses DNS servers provided by your ISP or carrier, which are not always the fastest or most secure. Changing these addresses to more performant alternatives, such as Google or Cloudflare, can significantly reduce response times and bypass some resource access restrictions.
The procedure for changing DNS settings on the platform Android has become much easier in recent versions of the operating system. Now users have access to both classic configuration methods for each Wi-Fi network individually, and a global parameter Private DNSthat encrypts requests and applies to all connections, including the 4G/5G mobile network. In this article, we will analyze both approaches in detail, consider the necessary addresses and answer common troubleshooting questions.
Before you start editing system parameters, it is important to understand that incorrect data entry can lead to a complete loss of Internet access. However, unlike changing the IP address, a DNS error can usually be easily corrected by returning to automatic settings. We will look at safe ways to make changes that do not require obtaining root access or installing complex third-party software.
Why do you need to change DNS on your smartphone?
The main reason for switching to third-party name servers is the desire to speed up request processing. When you enter a website address in your browser, the device sends a request to the DNS server, which resolves the domain name into a digital IP address. If the provider's server is overloaded or located geographically far away, this process takes extra milliseconds, which adds up to a noticeable delay. Using optimized services, such as Cloudflare or Quad9, often solves this problem.
The second important aspect is security and privacy. Many providers log your requests or use DNS to redirect to pages with advertising if you enter an address incorrectly. Modern protocols such as DNS-over-TLS (DoT), supported in Android 9 and above, encrypt this traffic, making it invisible to intermediaries. This is especially true when connecting to public hotspots in cafes or airports.
⚠️ Attention: Some corporate networks or educational institutions use their own DNS to filter content. Changing settings in such networks may violate internal regulations or block access to the organization's local resources.
Also, changing DNS helps to bypass blocking of individual sites if the provider uses filtering at the domain name level. Although it is not a full-fledged anonymization tool like a VPN, for many users it becomes an easy way to access the information they need without installing additional tunneling.
Preparation: choosing a reliable DNS service
Before getting into the system settings, you need to decide on a service provider. The market offers several proven options, each of which has its own advantages. The choice depends on your priorities: maximum speed, enhanced protection from malicious sites, or complete anonymity.
The most popular solution remains the infrastructure from Google. Their public servers are highly stable and fast almost anywhere in the world. For those who prioritize privacy and protection against phishing, an excellent choice would be Quad9, which automatically blocks access to known threats.
- 🚀 Google Public DNS: Main addresses 8.8.8.8 and 8.8.4.4. The ideal balance of speed and reliability for most users.
- 🛡️ Cloudflare: Addresses 1.1.1.1 and 1.0.0.1. Positioned as the fastest in the world with an emphasis on privacy (they do not sell user data).
- 🔒 Quad9: Address 9.9.9.9. Specializes in security, blocking domains associated with malware and botnets.
- 🇷🇺 Yandex.DNS: Offers "Basic", "Safe" and "Family" modes. Convenient for those who want to filter content at the provider level.
Write down the selected addresses or domain host name, as you will need them during the setup process. To use the feature Private DNS in new versions of Android, you often need a domain name (for example, dns.google), rather than a digital IP address.
If you don't know which server to choose, start with Cloudflare (1.1.1.1). Statistics show that it often provides the lowest latency (ping) for mobile devices in Europe and the CIS.
Setting up DNS for a specific Wi-Fi network
The classic method of changing parameters is suitable for all versions of Android, starting with the earliest ones. This method allows you to set individual settings for each access point. This is useful if you want to use fast DNS at home, but leave automatic settings at work.
To begin, open the menu Settings and go to the Wi-Fi (or Network and Internet). Find the network you are currently connected to in the list and click on it. On some devices, you need to long press (tap and hold) on the name of the network, after which a context menu will appear.
Select item Change network or Manage network settings. In the window that opens, find the section IP settings and switch the value from DHCP to Static (Static). This action unlocks fields for manually entering addresses.
☑️ Algorithm for changing DNS in Wi-Fi
Scroll down the list to the fields DNS 1 i DNS 2. Enter the previously selected addresses there. For example, for Google it will be 8.8.8.8 in the first field and 8.8.4.4 in the second. The remaining fields, such as IP address and gateway, do not need to be changed if you do not understand network addressing - the system usually substitutes them automatically when switching modes.
After entering the data, press the button Save. The device will reconnect to the network and the new settings will take effect. To check the result, you can open a browser and load several “heavy” sites or use special services to check for DNS leaks.
Global setting of Private DNS (Android 9+)
Starting with version Android 9 Pie, the system has a function Private DNS (Private DNS). This is a more advanced method that uses the DNS-over-TLS protocol. The main advantage is that the setting is applied globally: it works for both Wi-Fi and mobile data, protecting all device traffic.
Unlike the static setting, you cannot enter IP addresses like 1.1.1.1 here. You are required to enter the provider hostname. You can find this parameter in the menu Settings → Network and Internet → Private DNS. On smartphones Samsung or Xiaomi the path may be slightly different, but the name of the item is usually preserved.
| Provider | Host name to enter | Features |
|---|---|---|
dns.google |
High speed, global network | |
| Cloudflare | 1dot1dot1dot1.cloudflare-dns.com |
Maximum privacy, DDoS protection |
| Quad9 | doh.quad9.net |
Blocking malicious domains |
| AdGuard | dns.adguard.com |
Ad blocking at the DNS level |
Select a mode Private DNS provider host name and enter the appropriate value from the table above. After saving, the system will check the availability of the server. If the name is entered correctly, the error icon will not appear, and the Internet will continue to work stably.
Private DNS mode encrypts your requests, so the Internet provider does not see which sites you visit, seeing only the encrypted data stream to one server.
Worth Please note that if the server you specified becomes unavailable, the Internet on your phone may completely disappear until you return the setting to Auto or Disabledmode. Therefore, use only proven and reliable services.
Use of third-party applications for DNS management
If the built-in system tools seem inconvenient to you or you want to quickly switch between different profiles (for example, "Home", "Work", "Games"), you can use specialized applications from Google Play. Such utilities often have a one-click interface and additional monitoring functions.
Popular applications such as Intra or DNS Changercreate a local VPN tunnel on the device. This allows you to redirect DNS queries without the need for root privileges. When you launch such an application, a key icon will appear at the top of the screen, indicating that the service is active.
The advantage of software solutions is flexibility. You can configure a specific DNS to automatically turn on when connecting to a specific Wi-Fi network or set an operation schedule. In addition, many of them provide statistics on the number of requests blocked or loading speedup.
⚠️ Warning: Applications that use a local VPN to change DNS may conflict with real VPN services. You cannot activate them at the same time - you will have to choose what is more important to you at the moment: IP anonymity or a specific DNS server.
When choosing an application, pay attention to the permissions and reputation of the developer. Since all your traffic goes through their service, you should only trust open projects with a good review history and a transparent privacy policy.
Why do apps require permission to create a VPN?
This is a technical feature of Android. To intercept and modify a system's DNS requests without root privileges, the application must create a virtual network interface. In this case, the data does not go to third-party servers (if this is not a proxy mode), but is processed locally and redirected to the DNS of your choice.
Diagnosing problems and clearing the DNS cache
After changing the settings, you may encounter a situation where some sites do not open, and others load incorrectly. This is often due to the fact that old recordings are stored in the device's memory. Android caches DNS responses to speed things up, and sometimes this cache needs to be cleared manually.
The easiest way to update information is to use airplane mode. Turn it on Airplane mode for 10-15 seconds, and then turn it off. This will forcibly recreate the network connection and reset temporary network tables.
Deeper cleaning is possible through the hidden developer menu or special commands, but for the average user, rebooting the smartphone is enough. If the problem persists, check to see if there are any typos in the addresses you entered. Even one extra digit in 8.8.8.8 will make the server unavailable.
It is also worth considering that some applications have their own built-in name resolution mechanism, which can ignore system settings. In such cases, only updating the application itself or using the Private DNS mode, which intercepts traffic at a lower level, helps.
☑️ What to do if the Internet is lost after changing the DNS
Frequently asked questions (FAQ)
Will changing DNS reduce my Internet speed?
In the vast majority of cases, the speed will increase or remain the same, since the response time of Google or Cloudflare servers is less than that of local ones providers. However, if you choose a server physically located on another continent, the delay may increase by several milliseconds.
Do you need to change DNS on the mobile data (4G/5G)?
If you use the setup method for a specific Wi-Fi network, then the changes will not be applied on the mobile data. To change DNS for a cellular network, you need to use the Private DNS function (available on Android 9+) or third-party applications with local VPN mode.
Is it safe to use public DNS servers?
Yes, it's safe. Major providers such as Google and Cloudflare have strict privacy policies and use advanced encryption protocols. This is even safer than using standard servers from small providers, which may not encrypt requests.
How to return all settings back?
For Wi-Fi, go to the network settings, select Static and switch back to DHCP. For global settings, go to the menu Private DNS and select mode Disabled or Auto.
Will changing help? DNS bypass Roskomnadzor blocking?
Partially. If a site is blocked by adding its domain name to the blacklist of the provider's DNS servers, then changing the DNS will help open the resource. However, if the blocking is carried out by IP address or using DPI (Deep Packet Inspection), simply changing the DNS will not help, and a VPN will be required.
