+.Sh DESCRIPTION
+.Nm
+sends an IPv6 multicast listener discovery (MLD) query packet toward
+the specified multicast address,
+.Ar maddr ,
+toward interface
+.Ar intface .
+If you omit
+.Ar maddr ,
+linklocal all nodes multicast address(ff02::1) is used.
+.Pp
+After sending a query,
+.Nm
+waits for replies for at most 10 seconds.
+If a reply is returned,
+.Nm
+prints it with its type and then waits for another reply.
