Device discovery from a Host computer (mDNS Scanning)#

Device discovery for commissioning over the operational network happens over DNS-SD. DNS-SD is handled over mDNS on WiFi and using an SRP server on a boarder router for thread. On a computer, you can use the built-in mDNS applications to discover devices for the purposes of testing. Avahi is the standard mDNS program for linux, dns-sd is used on macs.
