mDNS [-E -F -A -U -N -T -M] mDNS -B type domain mDNS -L service_name _ app_protocol ._ transport_protocol domain mDNS -R service_name _ app_protocol ._ transport_protocol domain port [ string ] . . .
A basic client for Rendezvous multicast DNS (mDNS), primarily used for testing local mDNS service. When invoked with no arguments, it prints a usage statement to standard error. In most instances, the command doesn't return on its own, so you'll need to use Ctrl-C to break out.
When registering or looking up a name like website._http._tcp.local. , website is the service_name , http is the app_protocol , tcp is the transport_protocol , and local is the domain . For example, to register such a service:
% mDNS -R website _http._tcp local 80 "my web site"
Tests mDNS by repeatedly adding, updating, and then deleting an HINFO resource record for Test._testupdate._tcp.local. .
