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 num‐
ber:
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.
