aren't you mistaking it for /etc/networks ?

ETHERS(5) FreeBSD File Formats Manual ETHERS(5)
NAME
ethers - ethernet address database
DESCRIPTION
The ethers database contains information regarding known 48-bit ethernet
addresses of hosts on an Internetwork. The data is stored in a file
called /etc/ethers in the following format:
ethernet-address fully-qualified-host-name
Items are separated by any number of blanks and/or tab characters. A
``#'' at the start of a line indicates the beginning of a comment that
extends to the end of the line. A ``+'' at the start of a line will
cause the ethers(3) library functions to use data stored in the NIS(4)
ethers.byname and ethers.byaddr maps in addition to the data in the
/etc/ethers file.
An ethernet address is expressed in ASCII form as "x:x:x:x:x:x" where x
is a hexadecimal value between 0x00 and 0xFF. The address values should
be in network order. Hostnames specified in the /etc/ethers database
should correspond to entries in the hosts(5) file.
