ETHERS(5)                 FreeBSD File Formats Manual                ETHERS(5)

NAME
       ethers - Ethernet address to hostname database or NIS domain

DESCRIPTION
       The ethers file contains information regarding the known (48 bit)
       Ethernet addresses of hosts on the Internet.  For each host on an
       Ethernet, a single line should be present with the following
       information:

              Ethernet-address    official-host-name

       Items are separated by any number of blanks and/or TAB characters.  A
       `#' indicates the beginning of a comment extending to the end of line.

       The standard form for Ethernet addresses is ``x:x:x:x:x:x'' where x is
       a hexadecimal number between 0 and ff, representing one byte.  The
       address bytes are always in network order.  Host names may contain any
       printable character other than a SPACE, TAB, NEWLINE, or comment
       character.  It is intended that host names in the ethers file
       correspond to the host names in the hosts(5) file.

       The ether_line() routine from the Ethernet address manipulation
       library, ethers(3N) may be used to scan lines of the ethers file.

NOTES
       The Network Information Service (NIS) was formerly known as Sun Yellow
       Pages (YP).  The functionality of the two remains the same; only the
       name has changed.

                                19 October 1987                      ETHERS(5)
