Smart DNS is an advanced service some VPNs offer that configures a device’s Domain Name Server (DNS) to help you connect it to your chosen VPN. It works great at unblocking geo-restricted content, but it does not conceal your IP address.
This means that it can’t encrypt your connection or keep you anonymous online – the true purpose of a VPN.
Apple TVs don’t support native VPNs, so a Smart DNS is a good workaround for users simply looking to bypass firewalls or access foreign streaming libraries. For a full VPN solution on your Apple TV, we recommend installing a VPN on your router directly.
