  constant mapping
  
     Some TCP software constructs the destination Ethernet address
     from the top 24 bits of the Ethernet address followed by the
     low 24 bits of the (class A) destination Internet address.
     For this scheme the top 24 bits of the Ethernet address must
     be the same on all hosts on the net.  Contrast ARP.
