ethers(4)                                                         ethers(4)

NAME
     ethers - Ethernet address to hostname database or domain

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

          Ethernet-address    official-host-name

     Items are separated by any number of SPACE 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(4) file.

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

FILES
