Parameter

 

node-specification

   Supplies either the node name or the node address of the target
   node. If you supply the node name, the node address is obtained
   by looking up the node name in the LAN volatile node database. If
   you supply the node address, the corresponding node need not be
   defined in the LAN volatile node database. The canonical form of
   the address consists of 6 hexadecimal byte characters separated
   by hyphens. Use a colon as the separator character to indicate
   the bit-reversed form of the address.
