  Reverse Address Resoloution Protocol.  When someone connects to me,
  I can always geet the IP address they are connecting from.  Using
  RARP, I can turn the address into a machine name, and compare it
  with what you tell me on the "HELO" and "MAIL FROM:" lines.

RARP does hardware address/IP address translation.
