mld6query —
| mld6query | [ -dr] intface
      [maddr] | 
mld6query sends an IPv6 multicast listener discovery
  (MLD) query packet toward the specified multicast address,
  maddr, toward interface intface.
  If you omit maddr, linklocal all nodes multicast
  address(ff02::1) is used.
After sending a query, mld6query waits for
    replies for at most 10 seconds. If a reply is returned,
    mld6query prints it with its type and then waits for
    another reply.
This program is provided only for debugging. It is not necessary for normal use.
With -d, mld6query
    will transmit MLD done packet instead of MLD query packet. With
    -r, similarly, MLD report packet will be
    transmitted. -dr options are for debugging purposes
    only.
mld6query utility exits 0 on success,
  and >0 if an error occurs.
mld6query command first appeared in WIDE/KAME IPv6
  protocol stack kit.
mld6query does not take care of multicast addresses
  which have non link-local scope.
