NAME
     ethers - ethernet address to hostname database
SYNOPSIS
     /etc/ethers
DESCRIPTION
     The ethers database translates ethernet addresses to hostnames for use by
     the RARP daemon (see rarpd(8).)  /etc/ethers may look like this:
          0:0:c0:a:77:23      flotsam
          0:0:c0:a:68:ce      jetsam
     The six octet ethernet numbers must be entered as shown  above,  the  hex
     constants  must  use  lowercase  letters  and may not have leading zeros.
     Comments are marked with '#'.
     See rarpd(8) on why you shouldn't list Sun hosts in this file.
