.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
Ethernet MAC addresses are expressed as six hexadecimal numbers separated
|
|
by colons, e.g. "08:00:20:00:5a:bc".
