What is Private DNS?<\/h2>\n

Private DNS is a security feature that encrypts your DNS (Domain Name System) queries. To better understand why this matters, let’s first break down what DNS is.<\/span><\/p>\n

What is DNS?<\/h3>\n

DNS can simply be described as the \u201cphonebook\u201d of the internet. For instance, when you type a website name into your browser, like fastestvpn.com, your device needs the corresponding numerical IP address to connect to it.<\/span><\/p>\n

Upon this, a DNS server then translates that domain name into an IP address, which lets your browser load the site.<\/span><\/p>\n

However, what is the common problem with DNS requests? Unfortunately, most DNS queries, by default, are sent as unencrypted plaintext. This means your ISP, anyone on the same public Wi-Fi network, or a hacker with the right tools can see what websites you’re visiting.<\/span><\/p>\n

How Does Private DNS Work?<\/h3>\n

Private DNS encrypts your DNS queries with secure protocols. Instead of sending requests in plain text, it wraps them in an encrypted tunnel. This makes them unreadable to anyone monitoring your network traffic.\u00a0<\/span><\/p>\n

In layman\u2019s terms, it\u2019s like sealing a postcard in an envelope. The address is still visible, but no one can read the message inside.<\/span><\/p>\n

Private DNS vs Public DNS<\/h2>\n

Here are the differences:<\/span><\/p>\n

Public DNS (Default)<\/h3>\n

A public DNS is when your queries are sent in plain text. Your ISP or network administrator can see every domain you look up. Even though it\u2019s convenient, it exposes your browsing activities.<\/span><\/p>\n

Private DNS<\/h3>\n

It’s is when your queries are encrypted. Your ISP can see that you’re making DNS requests, but cannot read the particular domain names you visit. This significantly improves your online privacy.<\/span><\/p>\n

Is Private DNS Safe?<\/h2>\n

Yes, private DNS is generally considered safe, but not entirely. However, even though it\u2019s not the complete privacy solution, it does offer several important security benefits. It’s a specific tool for protecting one part of your internet traffic. Take a look below at a few privacy benefits of Private DNS:<\/span><\/p>\n

1. Enhanced Online Privacy<\/h3>\n

By encrypting your DNS queries, private DNS makes it much harder for third parties to see the domains your device is looking up. Regardless of whether you\u2019re worried about being tracked by your ISP, an advertiser, or a malicious actor over public Wi-Fi, private DNS adds an important layer of protection to your online activity.<\/span><\/p>\n

2. DNS Attack Prevention<\/h3>\n

Private DNS helps protect against several types of DNS-based cyber threats. These include:<\/span><\/p>\n
