First step: Access the router
If you want to change your DNS from the configuration of your router, open your browser and follow the steps presented below to access it:
Open the Windows command line (Windows key + R shortcut), type cmd in the opening line and confirm the entry
Then type ipconfig in the window and copy the number listed as "Standardgateway" to the clipboard
Insert this number in the address bar of your web browser, confirm it and connect with your access data
Second step: Configure another DNS
Select the option "Internet" in the menu and click on "Account Information"
Then click on "DNS Server"
Check the box that says "Use other DNSv4 servers"
If, for example, you want to use Google's DNS server, in the “Preferred DNSv4 server” field enter the address 188.8.131.52 and 184.108.40.206 in “Alternative DNSv4 server”. The specification made in this last field is used as a backup in case of a failure of the preferred DNS server.
Note: If instead of Internet Protocol 4 (IPv4) you prefer to use the sixth version of the protocol (IPv6), you will have to replace the server addresses. Google's public IPv6 DNS addresses are:
2001: 4860: 4860 :: 8888
2001: 4860: 4860 :: 8844
Change the DNS server on the router
In the "Internet" point of the router's configuration menu, a new DNS server can be installed
Change DNS from Windows
Step One: Show Network Connections
To configure DNS in Windows 7, Windows 8 or Windows 10 you must access the network connection settings. Click on the Windows key and enter "Network connections" in the browser, then select the item "View network connections." Alternatively you can enter the command ncpa.cpl and confirm it with the Enter key.
Usually, companies hire IT Specialists to solve technical problems, such as computer systems, software, hardware, networks, cloud platforms, etc.
If you use Windows 10 as your operating system, you just have to right-click on the Windows symbol and select the "Network Connections" option.
