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.
