What is a DNS profile?

A DNS profile is Apple's official mechanism for configuring DNS at the system level. Once installed, it automatically protects all apps on the device: Safari, Chrome, Mail, TikTok, and any other app — no additional configuration needed.

The profile uses DNS-over-HTTPS (DoH) — your DNS requests are encrypted and transmitted over the secure HTTPS protocol. Your internet provider cannot see which sites you visit, and ads and trackers are blocked before the page even loads.

The profile is active on all networks: Wi-Fi, mobile data, and others.

Step 1. Download the profile

Log in to your ADnull dashboard → Settings → click "DNS Profile for Apple".

The file adnull-apple-XXXXX.mobileconfig will be saved to your device.

FAQ

Does the profile work on mobile data?

Yes. The profile is active on all networks — Wi-Fi, 4G/5G, and others.

Does the profile affect internet speed?

No. DNS requests take milliseconds and have no impact on connection speed.

Is the profile safe?

Yes. The profile is generated individually for your account and only configures DNS. It does not collect data, intercept traffic, or change any other device settings.

Do not share the profile with anyone — it is tied to your personal DNS domain.

What if the profile won't install?

Make sure you are downloading the profile using Safari — on iOS, other browsers may not support installing configuration profiles.
