Many users experience unstable internet performance: pages load slowly, and some resources don't open at all, even though the connection indicator is green. Often, the root cause of the problem lies not with the provider or physical damage to the cable, but with the settings. DNS serversThis component is responsible for converting human-readable domain names (e.g., yandex.ru) into machine IP addresses, which are necessary for routing data packets.
By default, your device uses DNS, which is automatically provided by your ISP when you connect to the internet. However, these servers aren't always fast or reliable, which can cause delays when opening websites. Knowing how find out the Wi-Fi DNS server, allows you to diagnose your connection, identify configuration errors, or manually enter faster public addresses from Google or Cloudflare to speed up your internet experience.
In this article, we'll cover in detail methods for checking current network parameters on various operating systems, including Windows, Android, and iOS. You'll learn not only how to find the necessary numbers but also whether they need to be adjusted to improve connection quality. This is a basic home network administration skill that will help you quickly resolve resource access issues.
What is DNS and why should you check its address?
DNS stands for Domain Name System. Think of it like a giant internet phone book: when you type a website address into your browser, your device sends a request to a DNS server to get the corresponding IP address. If this "directory" is slow or contains erroneous entries, you'll wait a long time for pages to load or see a "Server not found" error.
Checking your current DNS server is necessary in several cases. First, it's to diagnose issues accessing specific websites while the internet is generally working. Second, it's a way to ensure that your router hasn't been reconfigured by a virus or malicious software to use malicious servers that could redirect you to phishing copies of banking websites. Connection security It directly depends on who you trust to resolve domain names.
⚠️ Attention: If you discover unknown DNS IP addresses during the scan that don't belong to your ISP or major public services (Google, Yandex), immediately reset your router settings and scan your computer for malware.
Furthermore, changing your DNS to a faster one can significantly speed up network response. Standard ISP servers are often overloaded, especially in the evenings, while specialized public services are optimized for high request processing speeds. Understanding how find out the Wi-Fi DNS server, gives you control over the speed and stability of your digital experience.
How to find DNS on a Windows computer
The Windows operating system provides several built-in tools for viewing network configurations. The fastest and most reliable method is using the command line. This method is universal and works on all OS versions, from Windows 7 to Windows 11, without requiring any additional software.
To obtain information, you need to launch the command line. Press the key combination Win + R, enter cmd and press Enter. In the window that opens, enter the command ipconfig /all and press Enter. The system will display a detailed list of all network adapters. Find the section that corresponds to your wireless connection (usually it's called "Wireless" or contains the word "Wireless").
☑️ DNS check on Windows
In the list of parameters for your adapter, look for the "DNS Servers" line. One or two IP addresses will be listed there. The first address is the priority, and the second is used as a backup if the first fails to respond. You can also use the graphical interface: go to Control Panel → Network and Internet → Network and Sharing Center, click on the name of your Wi-Fi connection, then select "Details." The window that opens will list "DNS Server."
It's important to distinguish between addresses obtained automatically and those entered manually. If the field says "Obtain DNS server address automatically," the device is taking its settings from the router. If the field shows specific numbers, it means changes have been made to the TCP/IP protocol properties. For most users, automatic acquisition is the best option, but manually setting public DNS (e.g., 8.8.8.8) often resolves speed issues.
Checking DNS settings on Android and iOS
Mobile device owners may also need to check network settings. Interfaces on smartphones and tablets may vary depending on the OS version and manufacturer's shell, but the general principle remains the same. Mobile operating systems often hide detailed technical data from the average user, but access to it is still possible.
On devices running Android the process looks like this:
- 📱 Open "Settings" and go to the "Wi-Fi" or "Connections" section.
- 🔍 Click the gear icon or arrow next to the name of the network you're connected to.
- ⚙️ Find "View advanced settings" or "IP settings".
- 👁️ If "Static" is selected, DNS servers will be explicitly specified. If "DHCP" is selected, click the "Advanced" button (if available) to view the current values.
On Apple devices (iOS) The situation is slightly different. In the standard iPhone and iPad interface, when connecting via DHCP (automatic), you can't see the current DNS server—the fields will be empty or hidden. To view or change them, go to Wi-Fi settings, tap the blue "i" icon next to the network, scroll down to the "DNS Setup" section, and switch the mode from "Automatic" to "Manual." Only then will the server addresses become visible or editable.
Why is DNS hidden on my phone?
Mobile operating systems strive to simplify the user interface. Since 95% of users never change their DNS manually, developers hide these technical details to avoid accidental errors that could lead to internet loss.
It's worth noting that Android 9 and later has included a feature called "Private DNS." This encrypts DNS requests, protecting them from ISP eavesdropping. If this feature is enabled, checking the default Wi-Fi settings may show empty fields, as requests are routed through a secure tunnel to a specified host (e.g., dns.google), rather than the standard IP address.
Viewing DNS through the router's web interface
The most accurate way to find out which DNS server your Wi-Fi network is using is to look at the router's settings. This is what distributes addresses to all connected devices. To do this, you'll need to access the router's control panel. Open a browser and enter the router's IP address (usually 192.168.0.1, 192.168.1.1 or 192.168.31.1).
After entering your username and password (they're located on a sticker on the bottom of the device, if you haven't changed them), find the section responsible for your internet connection. It may be labeled "WAN," "Internet," "Connection," or "Network." This is where you enter the settings received from your ISP or manually set by the user.
Interfaces from different manufacturers vary greatly, but the search logic is the same:
- 🌐 TP-Link: Network section → WAN → see the Primary DNS and Secondary DNS fields.
- 📡 Asus: "Internet" section → "Connection" tab → "DNS Settings" block.
- 🔴 Keenetic: "Internet" section → click on the active connection (WAN) → "IP and DNS settings" tab.
- 🟠 MikroTik: section “IP” → “DNS” (global router settings are indicated here).
⚠️ Attention: Router interfaces are constantly being updated. Menu locations may vary depending on the firmware version. If you don't find an exact match, look for sections labeled WAN, Internet, or DNS.
If the DNS fields contain addresses 0.0.0.0 If the parameters are blank, this means the router automatically receives settings from the provider. If they contain specific numbers (for example, 8.8.8.8), it means someone has manually changed the configuration. Changes in the router's web interface are applied to all devices on the network immediately, which is a huge advantage for centralized management.
Table of popular public DNS servers
If a review reveals that your current settings are ineffective, or you want to improve security and speed, it's worth considering alternatives. Several large organizations offer free DNS resolving services. They are often faster than ISP servers and have built-in protection against phishing sites.
Below is a table with the addresses of the most reliable and fastest servers currently available. You can use this information to manually configure your router or individual devices.
| DNS provider | Primary address (IPv4) | Alternate address (IPv4) | Peculiarities |
|---|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 | High speed, stability |
| Cloudflare | 1.1.1.1 | 1.0.0.1 | Focus on privacy, does not log requests |
| Quad9 | 9.9.9.9 | 149.112.112.112 | Blocking malicious domains |
| OpenDNS (Cisco) | 208.67.222.222 | 208.67.220.220 | Flexible content filtering settings |
| Yandex.DNS | 77.88.8.8 | 77.88.8.1 | Optimized for Russia, includes virus protection |
The choice of a specific provider depends on your goals. If maximum anonymity is important to you, Cloudflare is the best choice. If network-level virus protection is essential, consider Quad9 or Yandex.DNS (in secure mode). For most users, Google DNS remains the gold standard for reliability.
Diagnosing and changing network parameters
Once you've found your Wi-Fi server's current DNS address, you may need to change it. This can be done in the same menus where you checked it. On Windows, this is in the protocol properties. TCP/IPv4, on routers - the WAN section, on phones - Wi-Fi network settings.
When manually entering addresses, it's important to be precise. One extra digit or a misplaced period will result in a lost connection. After making changes, be sure to save the settings. Your computer may require a configuration update. To do this, run two commands in the command prompt (cmd):
ipconfig /flushdns
ipconfig /renew
The first command clears the local DNS cache, forcing the computer to re-query addresses from the server. The second refreshes the IP addressing. On routers, changes often require a reboot, although modern models apply the settings on the fly.
To diagnose problems, you can use the command nslookup. Enter in the command line nslookup google.comIn the response, you'll see which server processed the request (the Server line) and the IP address it received. This allows you to verify that your selected DNS is working correctly and isn't spoofing addresses.
Frequently Asked Questions (FAQ)
Can changing DNS speed up my internet?
Yes, it's possible. DNS doesn't affect file download speed (bandwidth), but it significantly speeds up response times when opening websites. If your ISP's server is slow, pages will take longer to load. Public DNS often processes requests faster.
Is it safe to use Google or Cloudflare DNS?
Absolutely. These are large international companies that value their reputation. Using their servers is often safer than using servers from unknown providers, which may intercept or log your requests. Furthermore, they support modern DNS-over-HTTPS encryption protocols.
What should I do if the Internet stops working after changing DNS?
Return to network settings and select "Obtain DNS server address automatically." You likely entered the numbers incorrectly, or the selected server is temporarily unavailable. Resetting to automatic settings will restore access through your ISP's servers.
Do I need to change DNS on each device separately?
No, it's not necessary. If you enter new addresses in your router settings, all devices connected to that Wi-Fi network (phones, TVs, laptops) will automatically start using the new DNS. Changing the settings on each device only makes sense if you want different devices to use different servers.
Does DNS affect ping in games?
DNS itself doesn't reduce ping (connection latency) during gameplay, as it's only used when establishing a connection to the game server. However, a fast DNS will help you find the optimal game server faster when launching the game, which can indirectly improve the experience, but won't change the physical packet latency.
