ethers - Ethernet address to IP number database
/etc/ethers contains 48 bit Ethernet addresses and their corresponding IP numbers, one line for each IP number:
The two items are separated by any number of SPACE and/or TAB char acters. 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.

ethers - database that maps Ethernet addresses to hostnames
The file is used in conjunction with the reverse address resolution protocol daemon, to map Ethernet addresses to hostnames. It contains
information about the known (48-bit) Ethernet addresses of hosts on the Internet.
For each host on an Ethernet, a single line should be present in the file with the following information:
Items are separated by one or more spaces or tabs. A number sign (#) indicates the beginning of a comment that extends to the end of line.
The standard form for Ethernet addresses is:
The x is a hexadecimal number between 0 and ff, representing 1 byte. The address bytes are always in network order.
Hostnames can contain any printable character other than a space, tab, newline, or number sign (#).
Hostnames in the file should correspond to the hostnames in the file or to those provided by the name service.
The following is a sample file: 08:00:20:01:e5:1c host1 # Comments go here 08:00:20:01:d0:4c host2 # Comments go
here 08:00:20:01:e0:1d host3 # Comments go here 08:00:20:00:c2:4e host4 # Comments go here
