However, it can have a massive impact on your online safety and cybersecurity. This may seem very technical and it is, but most users can actually make this change themselves just by following instructions. ## DNS Introduction When you type a website's name into your browser, it's not as simple as it seems. The Domain Name System (DNS) translates that name into a numeric IP address that computers understand. This translation allows you to access the desired web server. But why should you care about DNS? Well, it plays a crucial role in your online security, privacy, and even the speed of your internet surfing. ## What Do DNS Servers Do? Computers speak in numbers, but we prefer using memorable website names like pcmag.com. DNS servers act as translators, converting these names into numeric IP addresses, enabling our devices to reach the correct servers. ## Change DNS Servers? Your device usually sets up your DNS servers to work with your Internet Service Provider (ISP) but these servers are not always optimal or especially safe. Slow DNS servers can drag down your internet speed, especially when loading pages with content from various domains like ads. Switching to faster DNS servers can speed up your browsing, but more importantly, switching can also keep you much safer online - this is not a 'nice to have' - this is a MUST HAVE! ### Under the Hood for Security & Safety The DNS server setting impacts your device security in several ways. DNS stands for Domain Name System, which is a service that translates human-readable domain names (such as [www.AgainstScams.org](http://www.AgainstScams.org)) into numerical IP addresses (such as 254.254.254.254) that computers can understand. DNS servers are the ones that perform this translation service. By default, your device uses the DNS server provided by your Internet Service Provider (ISP), which may not be very secure or private. Your ISP can see and log all the websites you visit and may use this information for advertising or other purposes and may restrict or slow down some services, such as streaming video. A malicious DNS server can also redirect you to fake or harmful websites, or block access to certain websites. Some businesses offer specialized DNS services, such as what SCARS recommends: [Quad9](http://www.quad9.net). They filter out harmful websites, blocking them before reaching employees' browsers. Additionally, DNS-based parental controls help limit children's access to inappropriate content across all devices. Also, importantly, this is FREE! It is not a service you must subscribe to. In the case of QUAD9 it is based by IBM and the Global Cyber Alliance so it is not going away! ## Why Changing Servers Must Be Done For Your Online Safety To improve your device security, you should change your DNS server to a more secure and reliable one, such as Quad9 DNS. Their DNS servers offer features such as encryption, malware protection, phishing prevention, and content filtering. They also support DNS over HTTPS (DoH), which is a protocol that encrypts your DNS queries and prevents third parties from snooping on them. **Here's why you might want to change your DNS servers:** - **More security:** Some DNS servers offer additional security features, such as filtering out malicious websites or preventing DNS hijacking and cache poisoning attacks. - **Privacy:** Your ISP can see what websites you visit through their DNS servers. Some people prefer to use a different DNS server to keep their browsing history private. ## Privacy Concerns with DNS Servers When you browse the internet, your ISP's DNS servers see every domain you visit. Some ISPs use this to their advantage by redirecting your browser to an ad-laden page when you mistype a web address. This might seem harmless, but it compromises your privacy by sharing your browsing habits. Also, some 'typo' domains (domain names deliberately off a character or two) are malware delivery sites. ## DNS Threats: Phishing and Cache Poisoning Phishing scams involve fake websites that mimic legitimate ones, aiming to steal login credentials. By manipulating DNS caches, attackers can direct you to fraudulent sites without altering the address bar, making it difficult to spot the scam. Cache poisoning and DNS hijacking are techniques these scammers use to deceive users. Understanding these DNS threats and the potential downsides of using default DNS servers provided by your ISP can help you make informed decisions about your online security and privacy. Changing your DNS server to more reliable and secure options can greatly enhance your internet experience, ensuring a faster, safer, and more private browsing experience. ## Summary It is essential to change your DNS to a safer alternative, such as QUAD9. The best feature of Quad9 is that it prevents your browser from visiting dangerous domains and websites.
