The way the DNS works allows DNS providers to easily block certain domains such as ad servers. Ad-blocking and parental controls AdGuard DNS Moreover, some DNS providers such as AdGuard DNS and OpenDNS even provide content blocking services such as adblocking, parental controls, and even phishing protection on top of the basic DNS resolver services. Using a sophisticated DNS server with improved security protocols will offer better security from these types of attacks. The hacker then uses these fake DNS entries to route the web traffic to their intended website, thus making users fall for malicious websites designed to trick users into giving away critical personal information such as usernames, passwords, credit card and other bank details, and more. DNS cache poisoning is a method where the hacker replaces genuine website IP addresses with fraudulent IP addresses on the DNS server. This is what enables third-party DNS providers to offer enhanced privacy and security while browsing the web.Īttackers use methods such as DNS cache poisoning to breach user privacy, where the hacker corrupts the DNS cache of the target DNS server, leading to phishing attacks and thus, compromising user security. Modern DNS servers use newer technologies and improved DNS protocols such as DNS-over-HTTPS, DNS-over-TLS, and even the much recent DNS-over-QUIC protocol, which your ISP may not be using. One of the other things that third-party DNS server providers are good at offering is i mproved privacy and security. If you find that your ISPs are slow, you can switch to a DSN server provider that is providing better speeds and latencies for improved internet speed and reliability. On Android smartphones, this can be done via several third-party apps available on the Play Store, and on Mac and Windows, this can be done using the popular DNS benchmark program NameBench or Gibson Research Corporation’s Domain Name Speed Benchmark tool. You can check your current DNS server’s latency to check if you need to switch to a different DNS server. Third-party DNS servers are often faster and more reliable depending on the server locations. If your ISP’s DNS servers slow, your entire internet speed will be affected. Below are some of the benefits that third-party DNS services bring. You can choose to change the DNS server for your entire home network or your individual devices such as an Android device, tablet, laptop, Mac, iPhone, iPad, and more. Changing the DNS server can bring several improvements to your internet experience, including possible speed and reliability improvements, boost security and privacy, and even let you do things like ad-blocking and content filtering. That said, you can change the default DNS server using one of the available third-party DNS servers. You don’t have to rely on the default ISP servers, which might be slow or don’t properly work sometimes due to misconfigured servers. When it comes to DNS servers, you have a choice. Now that you know a little about DNS, here’s why you should change it: Why should you change DNS?ĭNS is one of the crucial infrastructures of the web and any issues with it mean your internet experience will be critically affected.
