How to turn on Private DNS on your iPhone — and why it matters

To install a configuration profile that controls DNS on an iPhone, open Safari and download the .mobileconfig file. Then go to Settings, General, VPN & Device Management, tap the profile name and install it; you will be prompted for your passcode. Profiles can be removed at any time, so install only from trusted sources.

To confirm installation, return to Settings, General, VPN & Device Management and check for the profile under Configuration Profiles. Most users add a private DNS service to increase protection against tracking and to avoid the limitations of an ISP’s DNS on public Wi‑Fi such as at a hotel, short‑term rental, or airport.

Some services can log and monetize browsing, but most popular private DNS providers do not. A private DNS can also block ads, prevent accidental connections to dangerous domains, and sometimes provide faster name resolution than your ISP. Trusted private DNS options include Cloudflare, NextDNS, Quad9, AdGuard DNS, CleanBrowsing, and Google Cloud DNS.
