It’s possible that you don’t know however, you should know that the Domain Name System (DNS) is an essential component of your ability to use the web.
What is DNS does? It transforms an Unified Resource Locator (the URL you type in to access the website) into an IP.
Instead of having recall and type in a complicated IP such as 18.104.22.168 instead, just enter google.com.
Also there are many of servers online that solely serve to transform the URLs you input into IP addresses which can be efficiently routed through the network to get to their destinations.
Of course, typing in the URL in your browser won’t immediately send an online request to translate. The browser first checks its local cache and determine whether the URL has been translated. Photo by Umberto on Unsplash
If it is it is, the process will be faster than if it must contact your configured DNS servers. If it is not, the request will be transmitted to the public DNS servers.
What is a DNS Server?
The servers responsible for the translation process described in the previous paragraphs are known as DNS Servers, and generally do just one thing. These servers employ some kind of software like BIND (also known as named) (pronounced name-dee) for handling translating between IP addresses as well as URLs. What is the location of those DNS servers?
Nearly each Internet Service Provider (ISP) has its individual DNS servers. In general you don’t have to be concerned about the configuration of these servers. But, there could be situations (such such as when your ISP’s DNS servers aren’t working properly) in which you’d like to utilize DNS servers provided by an outside party. For instance, Google has their own DNS servers located at 22.214.171.124 as well as 126.96.36.199.
It is possible to, with no issues using Google’s DNS in lieu of your ISP’s. If your job requires outsource to Latin America, your computer won’t care about which DNS servers you choose to use for as long as they can properly translate.
But there’s a caveat, however when you’re using the traditional DNS servers, you run the risk of privacy.
The Lack Of Privacy in DNS
If you’re using standard DNS servers, each URL you type as well as every search query you input are transmitted as simple text. That is, anyone who has the ability to monitor the activities you’re performing through your internet browser.
Imagine back in the days when you’d write letters to loved ones, friends and companies, that each letter you wrote was sealed in an envelope. Anyone who came into contact with the letter could easily open it and read it before putting it back into the envelope the envelope, and mail it to its way. It’s a lot like the way you work using the standard DNS servers.
The system causes an extremely poor level of privacy, such the theft of identities. That’s where Private DNS can help.
What is Private DNS?
The proper definition of Private DNS is DNS with TLS or DNS using HTTPS. TLS is a shorthand for Transport Layer Security and HTTPS is the abbreviation for Hypertext Transfer Protocol Secure.
If you choose to use DNS using TLS and DNS over HTTPS All of your DNS requests are encrypted. In this way, you make it much harder for malicious third-party hackers to listen in on your web traffic.
Even if your work requires outsourcing software for outsourcing to Latin America, that DNS-dependent network traffic will be secure from hackers. It’s not obvious but it’s an additional security measure you’d like to use.
How Do You Use It?
How you utilize Private DNS will be based on the operating system you are using. Each operating system has different methods for setting up DNS entries. The majority of desktop operating systems default to automated DNS setup, meaning that the DNS server will match the ones provided from your ISP.
If you’re interested in configuring private DNS you’ll need to figure out how to set up DNS addresses on your particular platform and then choose the DNS server provided by a third party which offers DNS using TLS as well as DNS using HTTPS. An example of this would be CloudFlare. CloudFlare’s DNS servers have 188.8.131.52 as well as 184.108.40.206. These are the addresses you can use for DNS configuration.
If you happen to have an Android device running version 10, you can enable Private DNS Mode (from Settings > Network & Internet > Advanced) and then enter 1dot1dot1dot1.cloudflare-dns.com. Note it is that the CloudFlare address that is required to be used for the Android platform differs from the ones used on the standard PC operating system.
After you’ve set up your chosen platform to utilize private DNS you won’t see any noticeable slowdown in the speed of your network, but you’ll enjoy a lot more privacy while using the internet.
Give It a Try
There’s nothing wrong with trying Private DNS to try. It is possible to configure the operating system of your choice to utilize DNS via TLS as well as DNS via HTTPS. If you discover that your new DNS servers aren’t working the same way as your ISP’s servers, you are able to restore your original configuration. But the security that you can get by using Private DNS will outweigh the tiny change in speeds.
