ETHERS(5)                 NetBSD Programmer's Manual                 ETHERS(5)


NAME

     ethers - Ethernet host name data base


DESCRIPTION

     The ethers file maps Ethernet MAC addresses to host names.  Lines consist
     of an address and a host name, separated by any number of blanks and/or
     tab characters.  A ``#'' character indicates the beginning of a comment;
     characters up to the end of the line are not interpreted by routines
     which search the file.

     Ethernet MAC addresses are expressed as six hexadecimal numbers separated
     by colons, e.g. "08:00:20:00:5a:bc".  The functions described in
     ethers(3) and ether_aton(3) can read and produce this format.


FILES

     /etc/ethers  The ethers file resides in /etc.


SEE ALSO

BUGS

     A name server should be used instead of a static file.
