ethers — Ethernet
host name database
ethers file maps Ethernet addresses to
host names. Lines consist of an address and a host name, separated by any
number of blanks and/or tab characters. A
#’ indicates the beginning of a
comment; characters up to the end of the line are not interpreted by
routines which search the file.
Ethernet addresses are expressed as six hexadecimal numbers separated by colons. The functions described in ether_aton(3) can read and produce this format.
ethers file format was adopted from
SunOS and appeared in NetBSD 0.9b.
A name server should be used instead of a static file.
Lines in /etc/ethers are limited to
BUFSIZ characters (currently 1024). Longer lines
will be ignored.
