## 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  begin‐
       ning  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.
