I’m confused, the mDNSResponder code is very lightweight and already runs on embedded devices such as printers, cameras and may other low-memory and low-cpu devices.

What is your target memory and cpu size for an IoT device? Given that we’ve been using mDNS for more than a decade, the steady pace of improvement in semiconductors means that even the smallest device will have more than sufficient resources for mMDS.

Best,
Alf
