ethers - ethernet address to hostname database
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:
official host name
Items are separated by any number of blanks and/or tabs. 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 ether_line() routine from the ethernet address manipulation library,
ethers(3Y) may be used to scan lines of the ethers file.
