Web page loading speed and the availability of certain resources directly depend on your network hardware settings. Users often encounter situations where the internet is unstable, or their ISP blocks access to essential websites. In such cases, the first step to solving the problem is DNS check servers that your device uses to route requests.
Understanding where to look for these parameters allows you to not only diagnose network problems but also improve the security of your connection. Modern routers They provide flexible tools for network management, but access to them is sometimes hidden deep within the interface. We'll explore all the ways to obtain this information, from using the command line to logging into the administrator's web interface.
It's important to know your current settings so you can replace them with faster or more reliable alternatives, such as Google or Cloudflare, if necessary. This is especially true if your ISP provides slow or unstable default addresses. Let's look at the technical details that will help you take control of your network.
What is DNS and why should I check it?
Domain Name System, or DNS, acts as the internet's phone book. When you type a website address into your browser, your computer sends a request to the server, which converts the human-readable name into a digital number. IP address, which is necessary to establish a connection. If this process is slow or the server is unresponsive, pages will take a long time to load or may not open at all.
Checking your current values can help you determine whether you're using your provider's servers or third-party resources. Internet providers often assign their own nodes by default, which can be overloaded or filter traffic. Replacing them with publicly available ones can sometimes improve network response times.
In some cases, incorrect settings can cause certain websites to be redirected to ad-supported pages or blocked entirely. Therefore, knowing what address is registered in your router, is a basic skill for home network administration.
Checking DNS via the Windows command line
The fastest way to find out which addresses your computer is currently using doesn't require logging into your router settings. The Windows operating system stores this information in the network stack, and you can access it in seconds. This is useful if you need to quickly check whether changes to your router are being applied.
First, you need to open the command prompt. Press the key combination Win + R, enter cmd and press Enter. In the black window that opens, enter the command ipconfig /all and press Enter. The system will display a huge list of options, in which you need to find the section corresponding to your active connection (Ethernet or Wi-Fi).
In this list, look for the "DNS Servers" line. It will contain one or two numeric addresses. These are the ones your device uses for name resolution. If you see addresses that differ from what you expect, they may have been manually configured in the network adapter properties, overriding the router settings.
What should I do if addresses are not displayed?
Sometimes the command line may be empty or show 0.0.0.0. This means the computer hasn't received settings from the router's DHCP server. Try renewing the IP address lease with the ipconfig /renew command or rebooting the network equipment.
An alternative method for more advanced users is to use a utility nslookup. By entering in the command line nslookup google.com, you'll see the name and address of the server that processed your request in the response. This allows you to verify that the DNS is working correctly and responding to requests.
Login to the router's web interface
To change or view global network settings, you must log in to the administrative panel of your routerThis is where parameters are entered, which are then automatically distributed to all connected devices via the DHCP protocol. This interface can be accessed through any web browser.
You need to enter the gateway IP address in the browser's address bar. Most often, this is 192.168.0.1 or 192.168.1.1, however, the exact address depends on the device model and manufacturer. If the standard addresses are not suitable, they can be found through the command line (the "Default gateway" parameter in the command output). ipconfig).
After entering the address, the system will ask for your username and password. By default, many devices use admin/admin or admin/password, but if you've previously changed them for security reasons, use your own credentials. If you forget your password, you'll need to perform a factory reset.
☑️ Preparing to access your router settings
Interfaces vary greatly from manufacturer to manufacturer, but the logic is the same. Find the section responsible for WAN or Internet settings. This is where the fields for entering DNS addresses are located. Be careful: in some firmware versions, these settings may be hidden within additional menus.
DNS lookup in the settings of popular models
Navigating a router's menu can be confusing for a beginner, as each manufacturer names sections differently. Below is a table to help you navigate the interfaces of the most common brands.
| Router brand | Menu section | Subsection | Field names |
|---|---|---|---|
| TP-Link | Network | WAN | Primary DNS / Secondary DNS |
| ASUS | WAN | WAN DNS Setting | DNS Server 1 / DNS Server 2 |
| Keenetic | Internet | Main (or provider) | Preferred DNS |
| D-Link | Setup | Internet | DNS (manually) |
In devices TP-Link And D-Link It's common for addresses to be obtained automatically from your provider. To enter your own, switch the radio button to "Use the following DNS addresses." Only then will the fields become active for editing.
Routers ASUS And Keenetic have more advanced interfaces, where DNS settings can be duplicated in the LAN/DHCP section. It's important to understand the difference: WAN settings affect how the router itself accesses the internet, while LAN/DHCP settings affect the addresses it distributes to your phones and laptops. In most cases, you'll need to change them in the WAN section or in the basic connection settings.
⚠️ Note: Firmware interfaces are updated regularly. The menu item layout may differ from that described above. If you don't find an exact match, look for sections with the words "Internet," "WAN," "Network," or "Broadband."
Using public DNS servers
Once you've found the input fields, the question arises: what addresses should you enter? Standard provider servers aren't always the fastest. There are a number of time-tested public services that are faster and more reliable.
The most popular option is Google Public DNSTheir servers are located all over the world and provide high response speeds. To use, enter the following values:
- 🌐 Preferred DNS:
8.8.8.8 - 🌐 Alternative DNS:
8.8.4.4
Another reliable option is Cloudflare, which positions itself as the fastest and most privacy-focused in the world. They don't sell user data and maintain modern security protocols.
- 🚀 Preferred DNS:
1.1.1.1 - 🚀 Alternative DNS:
1.0.0.1
For users from Russia and the CIS, servers are also relevant Yandex.DNS, which have the function of filtering fraudulent sites.
- 🛡️ Basic:
77.88.8.8And77.88.8.1 - 🛡️ Safe (virus-free):
77.88.8.88And77.88.8.2
⚠️ Important: When manually entering DNS addresses, make sure you enter the numbers correctly. One incorrect number will completely disable internet access on all devices.
Diagnosing problems after changing settings
After saving the new settings, the router may require a reboot or reconnection to the provider's network. If the internet connection goes away immediately after changing the settings, first check that the numbers you entered are correct. A typo in the IP address is the most common cause of network downtime.
It's also worth checking whether your ISP blocks third-party DNS services. Some telecom operators use DNS hijacking, redirecting all requests to their servers regardless of your settings. In this case, changing the addresses in your router may have no visible effect, although your settings will still be displayed in the interface.
To check the availability of the new server, you can use the command pingOpen the command prompt and type, for example, ping 8.8.8.8If you see responses from the server with time in ms (for example, time=24ms), then there is a connection. If you see the message "Timeout exceeded," the server is unavailable.
Why hasn't the speed increased?
Changing your DNS doesn't increase your bandwidth (file download speed). It only speeds up website address lookups. If websites open instantly but videos take a long time to load, the problem is your bandwidth, not your DNS.
In rare cases, your ISP may bind network access by MAC address or require login through a portal. Changing your DNS won't help; other configuration methods are required. Always check your service provider's technical requirements.
Is it possible to set different DNS for different devices?
Yes, this is possible. To do this, don't change the settings in the router itself (leave them set to "Automatic"), but enter the desired DNS addresses in the network adapter settings of a specific computer or smartphone. In Windows, this is done through the TCP/IPv4 protocol properties; in Android, it's done in the Wi-Fi settings for the specific network.
Does DNS affect gaming speed (Ping)?
Indirectly. DNS is used only when establishing a connection to the game server. Once the connection is established, DNS is no longer involved. However, if the game server has multiple IP addresses, a fast DNS can help select the optimal route more quickly.
What is DNS 64 and NAT64?
These are IPv6 transition technologies. If your provider uses IPv6 and the site only operates on IPv4, these mechanisms help resolve the address. The average user typically doesn't need to tweak these settings unless the provider explicitly specifies such a requirement.
Is Google DNS safe to use?
Yes, it's technically safe. However, it's important to understand that Google will see your domain name search history. If complete anonymity is crucial to you, you should consider more private alternatives or using a VPN.
My router isn't saving DNS settings. What should I do?
Try updating your router's firmware to the latest version. If the problem persists, there may be a software glitch. Perform a full reset using the button on the device and set up the device again, carefully checking the information you enter.
