Changing DNS settings increases the speed of the Internet. You may not know it, but there are many protocols and processes that work in the background and ensure that your computer can perform all the functions for which it is programmed. An important component for accessing websites is DNS, which stands for Domain Name System.
In essence, DNS translates easy-to-remember web addresses for users (e.g. www.wikipedia.org) into IP addresses that browsers can use to access sites (e.g. 22.214.171.124 is the IP address owned by Wikipedia).
It is important to note that DNS is not managed by a system. In a corporate environment, it could be managed by a firewall or server, while at home it is probably managed by your ISP.
However, you can change your DNS settings in any way you wish. This could benefit you by providing you with greater stability, better performance and/or security if your current DNS configuration is not up to par.
When you change the DNS servers in Windows, you change the servers used by Windows to translate hostnames (such as www.xxx.net ) into IP addresses (for example 2xx.18x.1xx7.40 ). Since DNS servers are sometimes the cause of certain types of Internet problems, changing DNS servers can be a good step in troubleshooting.
Since most computers and devices connect to a local network via DHCP, there are probably already DNS servers automatically configured in Windows for you. What you will do here is to overwrite these automatic DNS servers with others of your choice.
The following are the steps required to change the DNS servers used by Windows. However, the procedure is slightly different depending on the version of Windows you are using.
How to change Windows DNS
In Windows, this is accomplished by first typing Network in the Start menu to access the Network and Sharing Center. Next, click on the name of your network in the upper right corner under Connections and choose Properties in the resulting window.
To access your DNS settings, you will need to double-click Internet Protocol version 4. If IPv6 is enabled, make the same changes to that entry too.
At the bottom of the IPv4 or IPv6 window, you will probably see the DNS server address automatically configured by your ISP. Go ahead and select Use the following DNS server addresses to enter yours.

Now, you will actually need to provide a DNS address. Fortunately, there are many available. Take a look at the list of public DNS servers there are many more than you could ever want or choose one of these two options, the most used.
Google DNS – 126.96.36.199 for primary, 188.8.131.52 for secondary.
OpenDNS – 184.108.40.206 primary, 220.127.116.11 secondary.
Depending on where you live, changing Windows DNS may also allow you to access blocked content. Try it and let me know what you think!
How to change Windows DNS with the command prompt
You can also change your preferred DNS server in Windows via Command Prompt. It is certainly not as simple as following the instructions above because you have to issue commands via the command line, but it is feasible.
- Open an elevated command prompt.
- Type netsh and hit Enter.
- When you see netsh> , type interface ip show config, then hit Enter.
- Find the network connection for which you want to change the DNS server.
- Type this command followed by entering, but be sure to replace Ethernet0 with the name of your connection and 18.104.22.168 with the DNS server you want to start using.
- The command has been entered correctly if netsh> is displayed again. Now you can close the command prompt.
Remember that setting up custom DNS servers for your computer only applies to that computer, not all other devices on your network. For example, you can change Windows DNS with a set of DNS servers and use a completely different set on a desktop, phone, tablet, etc.
Also, remember that DNS settings apply to the “closest” device on which they are configured. For example, if you are using a set of DNS servers on the router, your laptop and phone will also use them when they connect to Wi-Fi.
However, if the router has its own set of servers and the laptop has its own separate set, the laptop will use a different DNS server from the phone and other devices that use the router. The same is true if your phone uses a custom set.
