Understanding DNS and How It Relates to Windows 10
DNS, or Domain Name System, is essential to the internet. The system translates domain names, such as www.example.com, into IP addresses that computers can use to locate the website. Without DNS, the internet would not be able to function.
In Windows 10, DNS plays a vital role in the smooth functioning of the computer. When you type a website address into your web browser, the browser first contacts your computer’s DNS server. The server looks up the IP address of the website and then sends that address back to the browser. The browser then uses the IP address to contact the website and display it on your screen.
In Windows 10, DNS settings can be found in the Network and Sharing Center. Here, you can configure DNS settings for each network connection you have. These settings include the primary and secondary DNS server addresses and locations related to the DNS cache, which stores website addresses so they can be accessed more quickly.
If you ever experience problems with a website not loading, the issue is likely related to your DNS settings. You can try flushing the DNS cache, which forces the computer to fetch a new copy of the DNS information from the servers. This can help to resolve some issues related to DNS.
In Windows 10, DNS is an essential component for the smooth functioning of the computer and the internet. By understanding how DNS works and how to configure DNS settings in Windows 10 correctly, you can help ensure that your computer is running at its best.
