What is private DNS? Should you use it?

use private DNS for security

DNS is a layer in the Internet’s architecture and a protocol that translates domain names to IP addresses. A domain name is a human-friendly name that usually identifies a website or an Internet resource. For example, a domain name such as “example.com” identifies a website.

Types of DNS

There are two types of DNS: public DNS and private DNS. Public DNS is generally provided by an ISP. You can’t change DNS servers or add any more servers unless you have root permissions on your router. Private DNS is usually NOT provided by an ISP, it can also be offered by an ISP, or it can be listed on a second-level DNS server.

Why use Private DNS?

If you are worried about your personal information (name, email, etc..) being exposed on the internet, all you need to do is change your DNS (Domain Name Servers) to a private DNS. The best way to do this is to use a free DNS proxy service. You will still be able to access popular websites like Google, Facebook, Twitter, and Reddit, but you’ll be able to keep your personal information safe from prying eyes. Another way to do it is to update your Phone DNS to a private one.

What is the difference between public DNS and private DNS?

Public DNS is used to allow users to access websites such as Google and Facebook, where there is no type of security but to type the website name. Private DNS is used to secure the DNS requests. It will help you to access websites from any DNS server you want while using the private DNS server.

DNS can be used to track the IP address of anyone using the Internet (“fingerprinting” as they call it). The amount of information you can get and extract depends on the tools you use to find the information and most of the time it is limited. With a private DNS, your ISP cannot see your domain name. This allows you to make your Internet usage anonymous.

You will need to check if your phone accepts private DNS Settings to be updated, otherwise you will need to root your phone.

Should I use Private DNS or a VPN?

The main difference between a VPN service and Smart DNS is privacy. Even both of the tools allow you to access geo-restricted content, only a VPN encrypts your Internet connection, makes it more private and hides your IP address, and protects your online privacy when you access the web.

Is Private DNS better than VPN?

DNS is a better option because does not load the phone since it doesn’t run any software or app. It does not use encryption so you can enjoy the full speed of your standard internet connection. However, keep in mind that VPNs don’t always slow down your connection, If you use top notch quality VPNs ( check our post on NordVPN) you get the full speed and sometimes you online geo restrictions that you don’t otherwise see.. ex. youtube country specific shows (ex. japanese anime). If I were to choose, I would go with a quality VPN since it manages the who encryption process. Best to test the VPN before getting a full subscription since the speed will also depend on the networks it routes from.

Why you should use private DNS now

Your Internet traffic is your digital fingerprint, and if you use the same DNS servers for all of your devices or computers, it can make it easier for someone to track that traffic and possibly build a profile of your behavior online and if with enough data can predict your online activities and behavior for possible ad targeting or possibly something worse. Control what information about you goes out and protect yourself from prying eyes.
