39 .Nd send multicast listener query
50 utility sends an IPv6 multicast listener discovery (MLD) query packet toward
51 the specified multicast address,
57 linklocal all nodes multicast address(ff02::1) is used.
59 After sending a query,
61 waits for replies for at most 10 seconds.
62 If a reply is returned,
64 prints it with its type and then waits for another reply.
66 This program is provided only for debugging.
67 It is not necessary for normal use.
72 will transmit MLD done packet instead of MLD query packet.
75 similarly, MLD report packet will be transmitted.
77 options are for debugging purposes only.
80 The program exits with 0 on success, non-zero on failures.
87 utility first appeared in WIDE/KAME IPv6 protocol stack kit.
91 utility does not take care of multicast addresses which have non link-local
