Short on Time? Here Are the Best VPNs With SmartDNS in 2025

DNS vs VPN vs SmartDNS

Let’s dive into each one so you can figure out which best suits your needs:

What Is DNS and Custom DNS?

DNS is like the internet’s phonebook — it translates website names (like google.com) into IP addresses that servers can understand. By default, your Internet Service Provider (ISP) handles your DNS, but switching to a custom DNS like 1.1.1.1 (Cloudflare) or 8.8.8.8 (Google) can help speed things up and even add a little extra privacy, as it makes it harder for your ISP to monitor the websites you visit. Cloudflare’s DNS ranks among the fastest resolvers globally, with an average speed of about 15.21ms².

Keep in mind, though, that DNS doesn’t encrypt your traffic. So, while it might improve speed, your ISP can still see your general activity, and you’re unprotected on public WiFi. If you want to change your DNS settings, here’s how:

Step 1. Open your device’s network settings. On Windows, go to Network & Internet, then click on Wi-Fi or Ethernet (depending on your connection type). On Macs and Linux, go to Network, and on iOS and Android, you’ll find it under Wi-Fi.

You can configure a DNS to work with all networks

Step 2. Look for the DNS settings under the DNS server assignment section. Click on Edit.

Automatic (DHCP) lets your device automatically get network settings from the router

Step 3. Enter the custom DNS addresses: 1.1.1.1 and 1.0.0.1 (Cloudflare) or 8.8.8.8 and 8.8.4.4 (Google).

You can also set a manual DNS for the iPv6 protocol

What is SmartDNS?

SmartDNS is ideal for streamers who want access to region-locked content without the slowdown of full encryption. It works by redirecting specific DNS requests that reveal your location, using proxy servers to make it appear as though you’re in a different country.

Because it only targets certain traffic and doesn’t encrypt your data, SmartDNS is much faster than a VPN for streaming. Just keep in mind that it’s designed for convenience, not privacy — so while it’s great for unblocking content, it won’t protect your online activity from snooping.

What is a VPN?

A Virtual Private Network (VPN) encrypts all your internet traffic and routes it through a secure server in a location of your choice. This not only disguises your real IP address but also protects your data from snoopers, hackers, and ISP throttling. According to a study, around 40% of the total VPN users rely on them to prevent tracking from search engines or social media sites³.

With the popularity of VPNs soaring — nearly one-third of internet users rely on them — they’re widely recognized as the go-to solution for privacy, secure browsing, and accessing region-locked services. Plus, an overwhelming 93% of organizations globally rely on VPN services⁴, driven by rising concerns over privacy, security, and the need for unfettered access to information.

While they can sometimes reduce your connection speed, many premium VPNs now offer optimized servers that keep buffering to a minimum.

Types of DNS, VPNs, and Smart DNS

There’s no one-size-fits-all when it comes to DNS, VPNs, or Smart DNS — each type is designed for specific needs, from speeding up lookups to securing networks to unblocking content. Here’s a quick overview of the most common types and what they’re used for:

DNS Types:

• Recursive DNS: Handles lookup requests by querying other servers on your behalf.
• Authoritative DNS: Stores and answers with the original domain records.
• Dynamic DNS (DDNS): Automatically updates DNS records for devices with changing IP addresses.
• Public DNS: Freely available services like Google DNS or Cloudflare’s 1.1.1.1.
• Private DNS: Used within organizations to manage internal traffic securely.

VPN Types:

• Remote access VPN: Lets individuals connect securely to a private network from anywhere.
• Site-to-site VPN: Connects entire networks (like office locations) over the internet.
• SSL/TLS VPN: Runs through a browser for easy, software-free access.
• IPSec VPN: Encrypts data at the network level for strong protection.
• Client-based VPN: Requires an app for access and control.
• Cloud VPN: Hosted in the cloud for flexible, remote access.

Smart DNS Types:

• Region-specific Smart DNS: Helps bypass restrictions in certain countries.
• Streaming-focused Smart DNS: Tailored for platforms like Netflix or Hulu.
• ISP-provided Smart DNS: Comes preconfigured from some internet providers.
• Customizable Smart DNS: Lets you tweak DNS settings manually.
• Dedicated Smart DNS: Built for businesses or specific devices like game consoles.

How to Use a VPN

Using a VPN is easier than you might think, and it can help keep your online activities private and secure. Here’s how to get started:

Step 1. Choose a VPN

Look for a reputable VPN that works with all your devices. If you have multiple gadgets, pick one that supports simultaneous connections or offers router compatibility to protect your entire network. ExpressVPN is a solid choice with a user-friendly setup, but most premium VPNs follow a similar process.

Step 2. Sign Up

Visit the VPN’s official website and select a purchase offer. Longer-term options often save you more money, and signing up directly (instead of through an app store) usually guarantees a money-back policy. Provide an email address and a valid payment method to complete the process.

Step 3. Install the App

Log in to your VPN account on the website, find the download page, and select your operating system. The installer will handle the rest. On Linux, you’ll typically use the command line. Luckily, ExpressVPN and other premium VPNs offer step-by-step guides for this.

Installing ExpressVPN is super quick

Step 4. Configure Your App

Sign in with your account details and any activation code you’re given. The VPN might ask if you want to share crash reports or auto-start on boot. You can also explore app settings to optimize your security (like using custom DNS servers) or enable any features specific to your needs.

You need an activation code, which you can usually find in your account on the VPN website

Step 5. Connect to a Server

In the app, choose a server in the country you want to virtually reside in. Some VPNs let you connect with a single click, while others may require you to press an additional connect button. Once it shows Connected, you’re ready to browse safely.

ExpressVPN has a “Smart Location” feature that connects you to the fastest server available

Step 6. Go Online Securely

With the VPN active, your traffic is encrypted and rerouted through a private server — often using the VPN’s own DNS or your custom DNS settings. This keeps your online activities both private and location-flexible.

You’ll find more configuration options in the settings

Where Can I Use DNS and VPN Online?

DNS and VPNs are super versatile and can be used together across various online activities, especially when you want to bypass geo-restrictions or keep your data secure. Here are a few common uses:

• Streaming. Safely access the popular streaming platforms (like Netflix, Hulu, and BBC iPlayer) from anywhere.
• Gaming. Reduce lag (prevent ISP speed throttling) and protect yourself from DDoS attacks with custom DNS and VPN servers (DDoS attacks will hit the VPN servers, rather than your home network).
• Online banking and email. Keep your transactions and communications safe with encryption.
• Work and remote access. Securely connect to company resources, even when faced with regional firewalls.

ExpressVPN uses automatic obfuscation to disguise VPN traffic as regular HTTPS traffic, so it can slip past firewalls and network filters undetected. This allows you to access websites and apps even on tightly restricted networks — like those in schools, workplaces, or countries with heavy censorship, where custom DNS services and non-obfuscated VPNs often get blocked.

MediaStreamer is ExpressVPN’s Smart DNS feature that reroutes DNS requests for supported streaming services. It doesn’t encrypt your data, but it improves speed and works on devices that don’t typically support VPN apps, like some smart TVs and game consoles. When we tested ExpressVPN with streaming platforms, our average download speed only dropped by 5%. This is impressive compared to other VPNs, which can slow you down by more than 50%.

One downside is that it can be costly. Luckily, ExpressVPN runs regular discounts. Best of all, you can try it risk-free, thanks to its 30-day money-back guarantee.

CyberGhost’s optimized server network makes it easy to find the best server for your needs. In our tests, we safely accessed multiple streaming platforms with minimal buffering, even though speeds were around 8% slower than ExpressVPN. Its user-friendly interface clearly labels specialized servers based on the platform they work with, and the ability to save favorites means you can reconnect with a single click any time you want.

Beyond that, CyberGhost provides SmartDNS for devices lacking native VPN support and dedicated IPs to reduce identity checks and blocks. My only gripe is that the monthly plans are expensive, with only a 14-day refund period. However, long-term options are more affordable. They also include a generous 45-day money-back guarantee so you can try CyberGhost for free.

How to Decide Between DNS and VPN

Trying to choose between DNS and a VPN? It really comes down to what matters most to you — speed, privacy, or a mix of both. DNS is great for speeding up your connection and handling simple access issues, while VPNs are the go-to for privacy, security, and getting around tougher restrictions. Here’s a quick breakdown to help you figure out what fits best:

• Privacy and protection. Want to keep your data private and hide your IP address? A VPN has you covered with strong encryption and IP masking.
• Speed. DNS can give you a slight speed boost since there’s no encryption involved, but it won’t protect your traffic from snooping.
• Accessing content. DNS changes might help with basic content restrictions, but if you’re dealing with stricter firewalls, VPNs tend to be more reliable.
• Cost. Tweaking your DNS settings is usually free or low-cost. VPNs, especially good ones, typically require an ongoing subscription.
• Setup. DNS settings are pretty easy to change manually. VPNs are just as user-friendly these days, with simple apps for most devices.
• Device support. DNS can work on nearly anything if you’re willing to configure it. VPNs offer dedicated apps, which makes setup even easier across multiple platforms.
• Extra features. VPNs often include added perks like kill switches, malware blocking, and multi-hop servers for better security and control.

Which Is Better: Custom DNS, Smart DNS, or VPNs?

We ran internal tests comparing custom DNS, Smart DNS, and VPNs to see how each one stacks up in terms of speed, content access, and privacy. Here’s a quick breakdown of what we found:

FAQs on DNS vs VPN

Is 1.1.1.1 DNS a VPN?

No, 1.1.1.1 is not a VPN — it’s a free public DNS resolver provided by Cloudflare that helps speed up your internet and improve privacy by handling your DNS queries securely, but it doesn’t encrypt your full internet traffic or hide your IP address like a VPN does.

Can I use DNS and VPN at the same time?

Yes, you can use DNS and a VPN at the same time — in fact, many VPN providers offer built-in SmartDNS features that let you combine the privacy of a VPN with the speed and streaming convenience of DNS. For example, services like ExpressVPN include SmartDNS (called MediaStreamer) so you can protect your traffic on one device while optimizing others for smoother streaming.

Why does DNS make use of UDP instead of TCP?

DNS typically uses UDP for most standard queries because it’s faster and more efficient — perfect for quick, one-off lookups that fit in small packets. But when responses are too large or certain operations are involved (like DNSSEC or zone transfers), DNS automatically switches to TCP for reliability and completeness.

What is a DNS leak?

A DNS leak is when your device sends DNS requests outside the encrypted VPN tunnel, typically to your internet service provider’s DNS servers, instead of routing them through the VPN. This exposes the domain names of the websites you visit, even if the rest of your internet traffic is encrypted and your IP address is hidden. Make sure you use a premium VPN to avoid DNS leaks.

DNS leaks can happen due to misconfigured network settings, operating system behavior, or VPNs that don’t fully protect DNS queries, and they undermine the privacy and anonymity a VPN is supposed to provide. You can easily check for DNS leaks yourself.

What is the DNS server 1.1.1.1 or 8.8.8.8?

1.1.1.1 and 8.8.8.8 are public DNS servers provided by Cloudflare and Google, respectively, that anyone can use to resolve domain names (like turning example.com into an IP address). They’re known for being fast, reliable, and more private alternatives to the DNS servers offered by most internet service providers. Cloudflare’s 1.1.1.1 emphasizes speed and privacy, while Google’s 8.8.8.8 is popular for its stability and wide compatibility.

To summarize, these are the best VPNs with SmartDNS enabled…
