!!! info ""

You usually do not need an explicit `mdns` server in addition to a [Local](./local/) server: the local server already routes queries for `*.local.` and IPv4/IPv6 link-local reverse zones via mDNS on non-Apple platforms and via the system resolver on Apple platforms. Add an explicit `mdns` server only when you want to reference it from [`preferred_by`](../rule/#preferred_by) or use it standalone.

Fields

interface

List of network interface names to send mDNS queries on.

When empty, all interfaces that are up, multicast-capable, and non-loopback are used.

Dial Fields

See Dial Fields for details.
