Multicast DNS Discovery (mDNS)

Sparky devices use multicast DNS (mDNS) to announce their presence on the local network, enabling automatic discovery without the need for manual IP configuration. This allows other devices to seamlessly detect Sparky devices within the same network.

A typical mDNS broadcast from a Sparky device includes the following information:

Hostname: sparky-6055F9B09714  
FQDN:     sparky-6055F9B09714.local.  
Address:  192.168.2.45:3602  
fw=82  
sn=6055F9B09714  
hwid=V3.0  
device=sparky

In this example:

• Hostname is the local device name on the network.
• FQDN (Fully Qualified Domain Name) shows the device’s network address with the .local domain.
• Address provides the device's IP address and port.
• fw, sn, hwid, device refer to device-specific identifiers like firmware version, serial number, hardware ID, and device type.
