Which Providers Offer Smart DNS?

FastestVPN: Smart Connect

Built-in Smart DNS for streaming. Easy setup on smart TVs and consoles. Included free with all plans.

NordVPN: SmartPlay

Automatically combines VPN + Smart DNS for optimal streaming. Transparent to the user — just works.

FastestVPN: Smart DNS

Available in account settings. DNS addresses for US and Netherlands. Manual setup required.

The Bottom Line

For remote work, security, and privacy: Always use a VPN. Smart DNS provides zero security.

For streaming on smart TVs/consoles: Smart DNS is faster and works natively on devices that can't install VPN apps. Use it for streaming only, on your secure home network.

Best of both worlds: Install a VPN on your router. This gives VPN encryption to all devices (including smart TVs) without needing Smart DNS.

Frequently asked

Frequently Asked Questions

Smart DNS reroutes only your DNS queries through a proxy in another country, making geo-restricted services think you're in that country. Unlike a VPN, it doesn't encrypt your traffic or change your IP address.
Yes, because Smart DNS doesn't encrypt your traffic. There's essentially zero speed penalty. This makes it ideal for streaming 4K content on devices that can't run VPN apps (smart TVs, older consoles).
No. Smart DNS provides zero encryption, zero privacy, and zero security. Your ISP can still see everything you do. It's purely for content unblocking — not security. For security, use a VPN.
Use a VPN for security, privacy, and remote work. Use Smart DNS only when you need geo-unblocking on a device that can't run a VPN app AND you don't need encryption (streaming on a smart TV at home).
