NAME
       ethers - Ethernet address to hostname database or domain
DESCRIPTION
       The 
ethers file is a local source of information about the (48-bit)
       Ethernet addresses of hosts on the Internet. The 
ethers file can be
       used in conjunction with or instead of other 
ethers sources,
       including the 
NIS maps 
ethers.byname and 
ethers.byaddr, or Ethernet
       address data stored on an LDAP server. Programs use the       
ethers(3SOCKET) routines to access this information.
       The 
ethers file has one line for each host on an Ethernet. The line
       has the following format:       
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 
SPACE, 
TAB, 
NEWLINE, or comment
       character.
