Make sure you use servers from trustworthy parties. The takeaway here is that the DNS server is very important. Indeed, while traveling to certain countries, you can access services not available in the local area by using different DNS servers.
Changing DNS settings allows you more control over your Internet access and can even free you from censorship. What is my DNS server?īy default, if you don’t do anything, your DNS server is that of your Internet provider, which gets the job done but is not necessarily the best. In short, a DNS server can impact the speed, privacy, and security of your online life. (As such, using DNS is one of the popular ways for networking vendors to provide “ Parental Controls” features.) More importantly, it has the ultimate control of where you can go on the Internet or block you from accessing specific sites, and so on. Since your first need to reach the DNS server before anywhere else on the Inter-web, as you can imagine, the server’s owner, among other things, has the first dibs on your online activities.Ĭonsequently, your DNS server has a log of what websites you visit. DNS is a matter of privacy and control, too The faster a DNS server is, the less time you need to wait to reach a website, resulting in a “faster” Internet experience - there’s less wait time before a webpage starts to materialize on the screen. In many ways, a DNS server is similar to the once-commonplace telephone directory service, where you only need to remember a person’s name and not their phone number. This page appears on your screen right now because such a process has worked. This process is necessary because computers only understand numbers while humans are pretty bad at remembering them. The browser then follows that IP address to load the website. web address or URL) and returns its IP address, which is a string of seemingly random numbers, to the browser - each website resides at an IP address. This server then looks up the website’s domain name (a.k.a. By default, that’s the server of the Internet provider. Whenever you access a website via its domain name, such as, the browser (Chrome, Firefox, Edge, etc.) first queries your DNS server.įor most homes, the Wi-Fi router holds the information of the DNS server in use. Here’s a typical example of the role DNS plays: (A DNS server is not to be confused with Dynamic DNS, which works somewhat the opposite way.)
