This command is the same as mDNS (see the entry later in this section), with the addition of the -P and -Q options.
As -R, but registers a service provided by a different host than the one on which dns-sd is run. It also creates a multicast DNS address record for that host.
Queries for arbitrary DNS resource records. The arguments are the fully qualified domain name of what you want to learn about, an RR type (such as A, PTR, TXT, SRV, etc.), and optionally an RR class (which defaults to 0, the IN class).
