If you've ever noticed that a page takes forever to load, that certain websites "disappear" for no apparent reason, or you're worried that your internet provider knows too much about what you do online, you'll probably be interested in this. Learn how to configure DNS on your Android mobile step by stepYou don't need to be an engineer or mess with anything complicated: with a few well-placed adjustments you can gain speed, privacy, and, as a bonus, bypass some blocks.
Behind something as simple as turning on Wi-Fi and accessing a website, there's much more to it than meets the eye. DNS servers are a fundamental part of how the internet works, but for most users, they remain... a largely unknown element that, when properly configured, enhances the browsing experienceLet's take a look at what they are, why it's a good idea to change the default ones, and how to do it on Android (and other devices) without getting confused and without depending on strange applications.
What is a DNS and what role does it play in browsing?
When you type "google.com" or "xatakandroid.com" into your browser, your phone doesn't actually understand fancy names, but numbers; what it needs to communicate with the servers is... an IP address like 216.58.211.142 or similar. This is where the Domain Name System or DNS, which acts as a kind of online address book or phone directory.
The DNS server receives the query from your device ("hey, where is this website?") and responds with the correct IP address, so that the browser can connect to the appropriate server. In this way, DNS translates easy-to-remember domain names into IP addresses that machines can understand.Without that intermediate step, you would have to memorize numbers for every page you visit, which would be a real nightmare.
In addition to translating domains, many modern resolvers They cache recent responses for a whileThis means that if you frequently visit the same website, the DNS will remember your IP address and be able to respond much faster the next time, shaving a few milliseconds off each page load time.
DNS servers: types, examples, and what you can use them for
By default, most mobile phones, computers, and routers use the Internet Service Provider's (ISP) DNS servers, which are automatically assigned via DHCP. However, many others exist. Alternative, free, public DNS servers focused on performance, security, or privacy that can be used instead.
Among the best-known providers that you can configure on Android and almost any device, some stand out, such as Google DNS, Cloudflare, OpenDNS or Quad9Its main characteristics and directions are as follows:
- Google Public DNSIt offers a robust, widely used, and stable service.
For IPv4, the addresses are 8.8.8.8 y 8.8.4.4For IPv6, the abbreviated addresses are 2001: 4860: 4860 :: 8888 y 2001: 4860: 4860 :: 8844On some routers or devices that do not accept the abbreviated syntax "::", you must enter the complete addresses with all the blocks, for example 2001:4860:4860:0:0:0:0:8888 y 2001:4860:4860:0:0:0:0:8844. - Cloudflare (1.1.1.1)One of the world's fastest DNS servers, with a strong focus on privacy. Its main IPv4 addresses are 1.1.1.1 y 1.0.0.1and the supplier assures that It does not sell your data and deletes records within 24 hours..
- OpenDNS (Cisco)It adds interesting features such as content filters, blacklists of malicious websites, and parental control options, very useful for businesses, schools or for managing the connection at home.
- Quad9 and security-oriented resolversThey focus on blocking domains associated with malware, phishing, or botnets, adding a additional layer of protection when browsing against dangerous pages.
In many cases it's a good idea to combine two services, for example using Cloudflare as the primary DNS and Google as the secondary for redundancyThis way, if one of the servers fails or is particularly slow, the other continues to respond to requests and your connection doesn't "die".
Why is it worth changing your Android's DNS settings?
Changing the DNS settings on your Android phone or tablet isn't just a geeky hobby; it has a direct impact on your browsing experience. One key reason is performance: If the DNS responds faster when you request a website's IP address, the page will start loading sooner.You're not going to turn a slow connection into NASA-level fiber, but you can gain speed and reduce some latency, especially if you frequently visit many different domains, play online games, or stream.
Secondly, there is security. DNS resolvers can suffer attacks such as... cache poisoning, where an attacker manipulates responses to redirect you to fake pagesSome public providers maintain lists of malicious domains to automatically block phishing websites, malware, or DDoS attack campaigns, providing extra defense without you having to install anything else.
There's also the issue of censorship and blocking. Many governments or operators block access to certain websites using DNS. prevent their resolvers from returning the IP addresses of those domainsIf you switch to a different DNS server, in many cases these blocks will no longer apply and you can access pages that appeared to be "down" but were actually just being filtered.
Finally, there's privacy. Your ISP's DNS usually allows the operator to know which domains you're querying and potentially use that data to monetize your activityFor example, by redirecting unsuccessful searches to pages with ads or by selling aggregated information to third parties. Changing your DNS, and even better, using an encrypted DNSYou reduce that exposure.
Changing DNS on Android: Versions, Limits, and Key Concepts
Android has improved a lot in this area over the years, to the point that Starting with Android 9 (Pie) there is a system-wide private DNS optionThis feature allows you to specify a provider that supports DNS-over-TLS, which encrypts name queries between your device and the resolver, and applies it to both WiFi and mobile data.
On devices with Android 8 or earlier versions, however, things are more limited: There is no global DNS setting for the entire system; you can only modify the settings for each individual WiFi network.This means you'll have to repeat the process network by network if you want to stop using the DNS servers of the router you're connecting to.
It's important to note that the exact menu path varies depending on the manufacturer's interface. What appears as "Networks and Internet" on one phone might be shown as "Connections" or "Wi-Fi and Networks" on another. Even so, The idea is always the same: locate the private DNS option in Android 9+ or the DNS1 and DNS2 fields within the advanced WiFi network settings.
It's important to know that Android 9 had a limitation: When using certain VPNs or DNS changing applications, the private DNS could be ignored.sending unencrypted queries to other resolvers. This behavior was largely fixed in Android 10 and later, but if you use a VPN it's advisable check which DNS server is actually using your connection.
How to set up private DNS on Android 9 (Pie) and later versions
If your mobile phone or tablet runs Android 9 or a later version, you're in luck because the system already includes the feature of Private DNS with DNS-over-TLS support to encrypt queriesThis is the cleanest way to set a DNS provider for the entire device, without having to configure each network individually.
The general stepsThe following steps, which may vary slightly depending on the brand, are for configuring private DNS:
- Open the app Settings on your Android device and go to the "Networks and Internet" section or similar.
- Access the advanced section where the option appears Private DNS (in some models it is directly accessible, in others it is within an "Advanced" submenu).
- Select option Private DNS provider hostname in order to specify a particular service.
- Enter the domain of the provider you want to use, for example:
- dns. google to use Google Public DNS with DNS-over-TLS.
- one.one.one.one if you prefer Cloudflare's encrypted DNS. - Press on Save and wait for the system to apply the new settings.
From that moment, the device will attempt Establish a secure DNS-over-TLS connection with the provider you specified on port 853If the service responds correctly, all your DNS queries will be encrypted between your mobile and that server, both over WiFi and mobile data (if the network allows it).
If at any point you want to revert to the original behavior, simply repeat the process and select the option Automatic or Disabled in the private DNS menuIn automatic mode, Android will attempt to use DNS-over-TLS with the server provided by the network; if this is not supported, it will silently revert to traditional clear-text DNS.
It's important to know that Android 9 had a limitation: When using certain VPNs or DNS changing applications, the private DNS could be ignored.sending unencrypted queries to other resolvers. In Android 10 and later versions, this behavior was largely corrected, but if you use a VPN, it's advisable to check which DNS server your connection is actually using.
How to change DNS on Android 8 and earlier versions (WiFi)
On devices with Android 8 or earlier, you won't have the system-level private DNS setting, so you'll need to change your DNS settings. network by network in the advanced settings of each WiFiAlthough it's a bit more cumbersome, it's still a good way to gain some privacy and bypass blocks when using wireless networks.
The typical procedure for modifying the DNS settings of a WiFi network in Old android It can be summarized in these steps:
- Connect the device to the WiFi network where you want to change the DNSbecause you can only edit its settings if you are connected or the network is saved.
- Open the app Settings and go to the "Wi-Fi" or "Networks & Internet > Wi-Fi" section, depending on the manufacturer.
- Locate the network you are connected to and press and hold its name until a pop-up menu with options appears.
- Choose the option Modify network, Edit network, or Manage network settingsdepending on the text your mobile phone displays.
- Deploy the Advanced from the network configuration form. If you don't see that text, it may be hidden behind an arrow or within the IP settings section.
- In the countryside IP settings, changes the mode from "DHCP" to StaticThis will allow you to manually enter the device's IP address, gateway, and, most importantly, the DNS fields.
- Check that the IP address, gateway, and network prefix length are correct (in many home networks, it's enough to keep the values ​​that appear), and scroll down to the fields DNS 1 y DNS 2.
- Enter in DNS 1 and DNS 2 are the IP addresses of the servers you want to useFor example, for Google DNS you could use 8.8.8.8 in DNS 1 and 8.8.4.4 in DNS 2; for Cloudflare, 1.1.1.1 and 1.0.0.1.
- Save the changes and wait for the phone to reconnect to the WiFi network with the new settings.
Once the network is reconnected, all name requests you make through that WiFi will be processed. They will go through the DNS servers you specified instead of those of the router.If at any time the network behaves strangely or you want to return to the original configuration, simply set the IP settings back to "DHCP" and the automatic values ​​will be restored.
Private DNS option on Android: enabling, disabling, and warnings
On many modern mobile phones with Android 10, 11, 12 or higher, private DNS is already included. enabled by default in automatic mode for all networks that support itThis means that the system will attempt to use DNS-over-TLS with the server provided by the network, and if that is not possible, it will simply revert to traditional unencrypted behavior.
If you want to force the use of a specific provider for reasons of trust, performance, or to bypass filters, you must select the mode Private DNS provider hostname and enter the service domain (such as dns.google or one.one.one.one). This configuration is applied at the system level and It unifies the DNS of all compatible networks, both WiFi and mobile data..
It's worth remembering a couple of practical details. If you misspell the hostname of your private DNS provider or the service becomes unavailable, Your device may stop resolving domains and it may seem like you have lost your internet connection.Even if your data or Wi-Fi connection is still active. If this happens, go back into your private DNS settings and set it to "Automatic" or "Off" to restore normal browsing.
Furthermore, the private DNS only It protects and encrypts DNS queries and responses, but does not encrypt the rest of your web or application traffic.To prevent anyone from seeing what specific data you send and receive, or to completely hide your IP address from third parties, the ideal solution is to combine a private DNS with a VPN with a strict no-logs policy that encapsulates all traffic.
DNS on other devices: Windows, macOS, Linux, ChromeOS, iOS, and routers
Although we focus on Android here, in practice it is recommended that, if you want total control, Configure a consistent DNS on the rest of your devices or directly on the routerThis ensures that computers, tablets, consoles, smart TVs, and mobile phones use the same name resolution policy, with its advantages in speed, privacy, and content unlocking.
DNS in Windows
In Windows (for example, Windows 10 or 11), you can change the DNS server from the network adapter settings: by accessing "Settings > Network & Internet > Status" or the "Network and Sharing Center" in the Control Panel. There, in your connection properties, you should open the properties of Internet Protocol version 4 (IPv4) or version 6 (IPv6) and check "Use the following DNS server addresses"Then, enter the IPs you want (like 8.8.8.8 and 8.8.4.4) and accept.
For macOS
On macOS, the change is made in "System Preferences > Network". Choose your interface (WiFi or Ethernet), click on "Advanced", and go to the tab DNS, where you can add new servers with the + button and remove old ones with the – button.The order in the list indicates which DNS is used first and which is kept as a backup.
In many Linux distributions that use NetworkManager, you access "Network Connections" from the system panel, select the connection, and then configure IPv4/IPv6. The IP addresses of the desired DNS servers are added in the comma-separated DNS server field.In environments without NetworkManager or on servers, the file can be edited directly. / Etc / resolv.conf to add lines like "nameserver 8.8.8.8", "nameserver 8.8.4.4", etc., or configure the DHCP client to prioritize public DNS servers over those of the ISP.
DNS on iOS
On iOS (iPhone or iPad), the adjustment is made for each WiFi network: go to Settings > Wi-Fi, tap the network information icon, then go to Configure DNS, select Manual and add the server addressesThis only affects that specific wireless network, not mobile data, unless you use a VPN or DNS app that handles all traffic.
ChromeOS DNS
On ChromeOS (Chromebook), DNS settings are changed from the network section of the system settings. Go to the network you're connected to, expand the "Network" section, and within that... Name servers, you choose Google Name Servers or Custom Name Servers, where you can write the IPs you prefer.
If you don't want to configure each device individually, the easiest way is usually to configure the DNS settings directly on the router. To do this, open your web browser and enter the router's IP address, which is usually something like this: 192.168.0.1, 192.168.1.1, or 192.168.2.1 192.168.1.100After logging in with your username and password, look for the Internet, WAN, or LAN settings section, where the fields usually appear. Primary DNS and secondary DNSThere you can replace your carrier's addresses with those of Google, Cloudflare, or other providers and save the changes.
Keep in mind that some operator routers They have their DNS locked at the firmware level and do not allow modification.In those cases, the alternative is to manually change the DNS on each device (as we've seen on Android) or use your own third-party router. And again, in IPv6-only environments, some devices require you to enter the complete eight sections of the address, without abbreviations with ::, padding the zeros with 0000 if necessary.
DNS, SmartDNS and VPN: differences and how they fit with Android
Changing the DNS on Android already represents a significant leap in control and privacy, but in the current ecosystem there is also much talk about SmartDNS and VPN, two related technologies but with different objectivesIt's important to understand what each one contributes in order to decide how to combine them.
A service of Smart DNS replaces your ISP's DNS addresses with those of the service provider.This involves adapting some responses to simulate connecting from a different geographic location. This is useful for bypassing certain content blocks, especially from streaming platforms that limit catalogs by country, but it doesn't encrypt traffic or change your public IP address.
The consequence is that, although you may have access to more content, your The connection with SmartDNS is not protected or encrypted on its own.Your operator, governments, or potential attackers on the local network will still be able to observe your activity unless you add additional layers of security.
An VPN (Virtual Private Network) goes much further: it creates an encrypted tunnel between your device and a remote serverBy hiding your real IP address and encapsulating all traffic (including DNS queries), most good VPNs integrate systems to use their own resolvers and prevent DNS leaks, so that even queries to the ISP are not leaked.
Some providers combine both a full VPN and a SmartDNS service in a single subscription, so that You can choose on each device whether you prioritize maximum security and anonymity or speed and access to content (For example, on smart TVs where you can't install a native VPN). On Android phones, it's usually easy to install the official VPN app and let it handle DNS, encryption, and region changes.
If you're simply looking for something easy, free, and without too many complications, Setting up a trusted public DNS on your Android device or router is a great starting point.If you want to secure all your activity, prevent deeper tracking, and minimize any DNS leaks, then it makes sense to consider additional leak protection.
