Sh NAME
Nm ifaliases
Nd interface aliases file
Sh DESCRIPTION
The
Nm
file specifies the additional addresses (aliases) that each interface
has.
Nm
is processed by
Pa /etc/rc.d/network
at system boot time.
Pp
Each line of the file is of the form:
D1 address interface [netmask]
Pp
The
Em address
is a network address of the alias.
This must be a number, or must be in
Pa /etc/hosts ,
since the nameserver is not running at this point.
Pp
The
Em interface
is the network interface the alias will be configured on.
Pp
The
Em netmask
is the netmask of the alias' network address.
Although this is optional, omitting the netmask is discouraged.
Omission results in the use of the classful netmask associated with
Em address .
Sh FILES
Pa /etc/ifaliases ,
Pa /etc/rc.d/network
Sh HISTORY
The
Nm
file appeared in
Nx 1.2 .
Sh BUGS

Please check

for alternatives like
