When you’re setting up a network on your computer, your IT team will set up both your preferred DNS server and a backup server. The primary DNS will always be contacted when your computer requests DNS, but if the preferred DNS server is unavailable, the alternate DNS will take over. The preferred DNS is the primary choice for most users. If your computer can’t reach your preferred IP address, your operating system will try another DNS until it finds the correct IP address.
A DNS server works by translating the addresses on the Internet. This process is affected by many factors, such as your ISP’s connection speed. However, the best DNS servers are designed to overcome such issues and provide the fastest possible route for information. Often, people blame their slow internet speed on their ISP or just bad luck. Changing your DNS server is not as difficult as it might seem. If your computer is capable of connecting to a third party DNS server, consider using it as your primary server.
While your ISP’s DNS servers are the default option, you can choose an alternative DNS server in case the preferred DNS server doesn’t respond within the specified time. Most of the time, the preferred DNS server is the best choice for most users, but if you have any concerns, you can check their FAQs before you select a server. You can also mix and match the two. For example, if you want to use Google Public DNS as your primary DNS, but want to access more websites, try using OpenDNS as an alternate.
When browsing the web, your preferred DNS server is the most reliable option. You may want to use a third-party DNS server to avoid logging your web activity and circumvent censorship policies. Some third-party DNS servers are more reliable and can help you prevent tracking and monitoring of your online activity. Although not all DNS servers avoid traffic logging, make sure to check out the FAQs on the DNS provider’s website.
The primary DNS server is the preferred DNS on your PC. If it’s unavailable, the alternate DNS is the second choice. The second is the secondary one. You can choose either one of them based on your needs. A third-party DNS server will give you the most reliable results. If you have more than one DNS, make sure that each of them is secure. Then you can switch to the preferred DNS when you need to.
If your DNS server is not available, you should switch to another server. The primary DNS server should be available at all times. You should also check whether your preferred DNS server allows you to block certain IPs. In some cases, it can even send out a notification that your primary DNS server is unavailable. But, you can’t change the IP address of your preferred DNS server. It is best to set a DNS server that’s compatible with your operating system.
Your preferred DNS server should be the same as your primary DNS server. If you’re using a cable modem, you should choose a DNS server that has an IPv4 address. You can also choose a DNS server for IPv6 if you don’t use the same protocol as your primary one. If you’re using a dial-up connection, your preferred DNS should be listed as your primary.
The DNS server is the first server your system uses to resolve name resolutions. It can resolve DNS queries for your computer. Then, your computer will find your preferred DNS server. Your alternate DNS server will be the one that is used when the primary DNS fails. Your IP address will be based on the IP address of your primary DNS. This can also be a temporary DNS server that is available if your internet service provider has changed its IPv6 addresses.
You can also specify the DNS server in your operating system. You should note the IP addresses of both the DNS servers you use. The preferred DNS is the one that you use when creating a DNS query. The alternate DNS is used when your primary DNS fails. In case of a DNS server failure, you should select the alternate. If your preferred DNS server is unavailable, the alternate DNS will be used. The alternative DNS server is the one that is selected if the primary fails.

Understanding DNS Servers
DNS, or Domain Name System, is a system that translates domain names (such as google.com) into IP addresses (such as 216.58.194.174), which are used by computers to communicate with each other over the internet. DNS servers are the backbone of this system, responsible for resolving domain names into IP addresses so that internet users can access websites and other online services.
Types of DNS Servers
There are two main types of DNS servers: recursive and authoritative.
Recursive DNS Server
A recursive DNS server is responsible for resolving domain names on behalf of the user. When a user types a domain name into their web browser, their computer sends a request to a recursive DNS server, which then queries other DNS servers to resolve the domain name into an IP address. Recursive DNS servers cache this information for a period of time so that subsequent requests for the same domain name can be resolved more quickly.
Authoritative DNS Server
An authoritative DNS server is responsible for providing information about a specific domain name. When a recursive DNS server queries an authoritative DNS server, it is asking for information about a specific domain name (such as the IP address associated with that domain name). Authoritative DNS servers are typically operated by the organization or entity that owns the domain name in question.
How DNS servers work
When a user types a domain name into their web browser, their computer sends a request to a recursive DNS server. The recursive DNS server then queries other DNS servers (starting with the root DNS servers) to resolve the domain name into an IP address. The process of resolving a domain name typically involves multiple DNS servers, with each server providing information about the domain name until the IP address is finally resolved.
Once the IP address is resolved, the user’s computer can connect to the web server associated with that IP address and retrieve the web page or other online content they requested.
DNS servers are critical to the functioning of the internet, as they allow users to access websites and other online services using human-readable domain names rather than hard-to-remember IP addresses. Without DNS servers, the internet as we know it would be much more difficult to use and navigate.
What is a Preferred DNS Server?
A preferred DNS server is the DNS server that a computer or device uses first when looking up IP addresses for domain names. In other words, it is the DNS server that a device will use by default unless otherwise instructed. The preferred DNS server is typically provided by the user’s internet service provider (ISP), but it can be changed to a different DNS server if desired.
How to set up a Preferred DNS Server
Setting up a preferred DNS server is a relatively simple process that can be done in the settings of most devices. The exact process may vary slightly depending on the operating system and device being used, but the general steps are as follows:
- Open the Network Settings or Internet Settings menu on the device.
- Locate the DNS settings or DNS server settings.
- Change the DNS server settings to the IP address of the preferred DNS server.
- Save the changes and exit the settings menu.
Benefits of using a Preferred DNS Server
There are several benefits to using a preferred DNS server, including:
- Increased internet speed: A fast and reliable DNS server can help improve the speed and responsiveness of web browsing and other online activities.
- Improved security and privacy: Some DNS servers offer additional security and privacy features, such as filtering out known malicious websites or blocking tracking cookies.
- Bypassing restrictions and censorship: Some DNS servers can be used to bypass website blocks or censorship imposed by governments or other entities.
Overall, using a preferred DNS server can help improve the speed and security of online activities, and give users more control over their internet experience.
It is important to note, however, that changing DNS server settings can sometimes cause issues with certain websites or online services, particularly if those services are designed to only work with specific DNS servers. Additionally, not all DNS servers are created equal, and some may be faster or more reliable than others depending on the user’s location and internet service provider. As such, it is important to do some research and choose a preferred DNS server that is appropriate for the user’s needs and location.
How to Change Your Preferred DNS Server
Changing the preferred DNS server on a device is typically a straightforward process that can be completed in a few steps. The exact process may vary depending on the device and operating system being used, but the general steps are as follows:
- Open the Network Settings or Internet Settings menu on the device.
- Locate the DNS settings or DNS server settings.
- Change the DNS server settings to the IP address of the preferred DNS server.
- Save the changes and exit the settings menu.

Tips for choosing a Preferred DNS Server
When choosing a preferred DNS server, there are a few factors to consider:
- Speed and reliability: Look for a DNS server that is fast and reliable, with a high uptime and low latency.
- Security and privacy: Some DNS servers offer additional security and privacy features, such as filtering out known malicious websites or blocking tracking cookies.
- Location: Choose a DNS server that is geographically close to your location, as this can help reduce latency and improve overall performance.
- Compatibility: Some websites and online services may only work with certain DNS servers, so make sure to choose a DNS server that is compatible with the websites and services you use.
Common issues when changing your Preferred DNS Server
Changing the preferred DNS server on a device can sometimes cause issues with certain websites or online services. For example, some websites may not load properly or may be blocked if the DNS server being used is not compatible with the website’s security protocols. Additionally, changing the DNS server settings can sometimes cause issues with network connectivity or other aspects of the device’s performance.
To avoid these issues, it is important to choose a DNS server that is reliable and compatible with the websites and services you use, and to test the new DNS server thoroughly before making it the preferred DNS server. If problems do arise, it may be necessary to switch back to the default DNS server or try a different preferred DNS server.

What is DNS in WIFI settings?
DNS in Wi-Fi settings refers to the Domain Name System (DNS) server that the device uses to translate domain names (such as google.com) into IP addresses that can be used to connect to websites and other online services. When a device connects to a Wi-Fi network, it typically receives DNS server information from the network’s router, which is then used by the device to resolve domain names.
In Wi-Fi settings, the DNS server can usually be set to either automatic (in which case the device will use the DNS server provided by the router) or manual (in which case the user can specify a preferred DNS server). Changing the DNS server in Wi-Fi settings can help improve network performance, increase security and privacy, or unblock websites that may be restricted by the default DNS server.
How do I find my DNS server?
The process for finding your DNS server depends on the device and operating system you are using. Here are some general methods for finding your DNS server on different devices:
- Windows 10: a. Click on the Start menu and select Settings. b. Click on Network & Internet. c. Select Change adapter options. d. Right-click on the network connection you want to check and select Status. e. Click on Properties. f. Look for the “Internet Protocol Version 4 (TCP/IPv4)” entry and click on Properties. g. The DNS server information should be listed under “Preferred DNS server” and “Alternate DNS server” (if applicable).
- Mac: a. Click on the Apple menu and select System Preferences. b. Click on Network. c. Select the network connection you want to check (such as Wi-Fi or Ethernet). d. Click on Advanced. e. Select the DNS tab. f. The DNS server information should be listed in the box labeled “DNS Servers.”

Scroll down and select “Show advanced options.” f. Look for the “IP settings” entry and select “Static.” g. The DNS server information should be listed under “DNS 1” and “DNS 2” (if applicable).
If the above methods do not work or you are using a different device or operating system, you may need to consult the user manual or perform a web search to find instructions for checking your DNS server.
Do you need DNS for Wi-Fi?
Yes, DNS is necessary for Wi-Fi to work properly. DNS (Domain Name System) is the system that translates human-readable domain names (such as google.com) into IP addresses that computers use to connect to websites and other online services. Without DNS, it would be difficult for people to remember the IP addresses of all the websites they want to visit, and it would be harder for computers to connect to those websites.
When a device connects to a Wi-Fi network, it typically receives DNS server information from the network’s router. This DNS server information is used by the device to resolve domain names into IP addresses. If there is a problem with the DNS server, the device may not be able to connect to the internet or may experience slow or unreliable network performance.
In some cases, users may want to change the DNS server used by their Wi-Fi network to improve network performance, increase security and privacy, or unblock restricted websites. However, DNS is still an essential component of Wi-Fi and is required for it to function properly.
