# doh.dns.apple.com

`doh.dns.apple.com` is an Apple host for DNS over HTTPS. Apple lists it for encrypted DNS resolution in iOS 14, iPadOS 14, tvOS 14 and macOS Big Sur and later.

Run by Apple · Ports: 443 TCP · Checked: 1 November 2026

## Short answer

Apple's DNS over HTTPS (DoH) host. Apple lists it for encrypted DNS resolution in macOS Big Sur and later.

Block with care

Blocking it can break the encrypted DNS lookups that macOS sends to Apple. Normal DNS through your router isn't affected.

Matches

`doh.dns.apple.com`

A name with `*.` covers every name under it: `*.push.apple.com` matches `1-courier.push.apple.com`.

## What it serves

Apple's enterprise host list names `doh.dns.apple.com` in its Domain Name System resolution section, “Used for DNS over HTTPS (DoH)”, on port 443. It supports proxies.

On a Mac, [`mDNSResponder`](https://kilobat.app/processes/mdnsresponder) does all DNS lookups. With encrypted DNS, the lookups go out over HTTPS instead of plain DNS.

Apple doesn't say which features use this host. Apple Platform Security says that iCloud Private Relay covers all DNS lookups.

## Processes that use it

- [mDNSResponder](https://kilobat.app/processes/mdnsresponder): Part of macOS. It handles system DNS lookups for apps and runs Bonjour on the local network, so its traffic can include other apps' name lookups.

## What breaks if you block it

Block with care

Blocking it can break the encrypted DNS lookups that macOS sends to Apple. Normal DNS through your router isn't affected.

What breaks if you block it

- Encrypted DNS lookups to Apple fail. Apps that depend on them may not connect.
- Features that use Apple's DoH, which Apple doesn't list, may fail.

With Kilobat Pro and the network filter, you can block a host for every app or for one app: in Connections, select a connection and choose Block. Apple’s own services are never blocked by Kilobat’s [Protection](https://kilobat.app/docs/blocking#protection) lists.

## Notes

Your own encrypted DNS profile, such as one from Cloudflare or NextDNS, uses its own host instead. See [Use encrypted DNS on a Mac](https://kilobat.app/guides/encrypted-dns-mac).

## Apple’s rules for its hosts

Apple’s list, [Use Apple products on enterprise networks](https://support.apple.com/en-us/101555), says that devices open these connections, not Apple’s servers. Apple services fail any connection that uses HTTPS interception, so a proxy that inspects TLS should leave Apple’s hosts alone.

If a firewall allows hosts by name, allowing `*.apple.com` covers most Apple services, Apple says. A firewall that works only with addresses can allow `17.0.0.0/8` for IPv4, and `2403:300::/32`, `2620:149::/32` and `2a01:b740::/32` for IPv6.

To see which app on your Mac opened a connection to this host, use Kilobat’s Connections tab, or the [agent network log](https://kilobat.app/docs/agents#agent-network-log) for AI agents.
