NAME
       ethers - Ethernet address to IP number database

DESCRIPTION
       /etc/ethers  contains  48  bit  Ethernet addresses and their corresponding IP numbers, one
       line for each IP number:

              Ethernet-address  IP-number

       The two items are separated by any number of SPACE and/or TAB  characters.   A  #  at  the
       beginning  of a line starts a comment which extends to the end of the line.  The Ethernet-
       address is written as x:x:x:x:x:x, where x is a hexadecimal number between 0 and ff  which
       represents  one byte of the address, which is in network byte order (big-endian).  The IP-
       number may be a hostname which can be resolved by DNS or a dot separated number.
