Why should I install a private DNS on iPhone?
Most users add a private DNS service on their iPhones to increase protection against tracking. Some services can log and monetize your browsing, but most popular private DNS providers don't. While your internet provider has a built-in DNS, you're left unprotected when you use public Wi-Fi networks, like at a hotel, short-term rental, or airport.
