mDNS Discovery

mDNS (multicast DNS) lets you reach your ESP3D device using a human-readable hostname like esp3d.local instead of an IP address — no DNS server required.

By default, ESP3D advertises itself as esp3d.local on the local network.

By operating system

Windows

Windows 10 and later include built-in mDNS support.

If it does not work, install Bonjour from Apple (included with iTunes).

You can also use a dedicated browser like Bonjour Browser for Windows to list all mDNS services.

Then navigate to:

http://esp3d.local

macOS / iOS / iPadOS

Supported natively via Bonjour — no installation needed.

Use Discovery - DNS-SD Browser to browse all mDNS services and find your ESP3D device.

Search for esp3d in the app.

Linux

Install Avahi, the standard mDNS daemon for Linux:

sudo apt install avahi-daemon avahi-utils

Then browse or resolve:

avahi-browse -a
avahi-resolve -n esp3d.local

Android

Use mDNS Discovery — search for esp3d to find your device.

Note

The mDNS hostname can be changed in your ESP3D settings. If you have multiple ESP3D devices on the same network, give each a unique hostname to avoid conflicts.
