- Encrypts traffic between your device and the VPN server
- Makes it harder for your ISP to see the sites you visit directly
- Can reduce exposure on public or shared networks
If you’re trying to make your browsing more private, two terms come up often: VPN and private DNS. They sound similar, and both can improve your internet experience, but they solve different problems.
Knowing the difference can help you choose the right tool instead of paying for something you may not need.

In simple terms, a VPN hides more of your activity from the network you’re using, while private DNS mainly protects the lookup step that turns a website name into an IP address. That distinction matters when you’re deciding how much privacy you actually want.
What a VPN does, and what it doesn’t
A VPN creates an encrypted tunnel between your device and a VPN server.
That means your internet service provider, public Wi-Fi operator, or local network can see that you’re connected to a VPN, but not the specific sites or services you visit through that tunnel in the same way they otherwise might.
A VPN is often useful if you use public Wi-Fi, want to reduce tracking on shared networks, or prefer to keep your browsing less visible to the network operator.
It can also help you add a layer of privacy when you travel or work outside your home network.
But a VPN is not a magic invisibility cloak. Websites can still recognize you if you log in, and advertisers may still track you through cookies, browser fingerprinting, or the accounts you use.
A VPN also does not make unsafe downloads safe or replace good account security practices.

Common VPN privacy benefits
- Encrypts traffic between your device and the VPN server
- Makes it harder for your ISP to see the sites you visit directly
- Can reduce exposure on public or shared networks
- May help separate your browsing from your home IP address
What private DNS does
DNS, or Domain Name System, is the service that translates human-friendly web addresses into the numerical addresses computers use. When you type a site name into your browser, your device usually asks a DNS resolver where to go.
Private DNS means that this lookup is encrypted, typically using DNS over HTTPS or DNS over TLS . That keeps third parties on the network from easily seeing which site names you are requesting during the DNS step.
Private DNS can be a smart privacy upgrade, especially if you’re worried about a network observing or tampering with your DNS requests. It can also help prevent some forms of DNS-based blocking or redirection.
