IFALIASES(5)              NetBSD File Formats Manual              IFALIASES(5)

NAME
     ifaliases -- interface aliases file

DESCRIPTION
     The ifaliases file specifies the additional addresses (aliases) that each
     interface has.  ifaliases is processed by /etc/rc.d/network at system
     boot time.

     Each line of the file is of the form:
           address interface [netmask]

     The address is a network address of the alias.  This must be a number, or
     must be in /etc/hosts, since the nameserver is not running at this point.

     The interface is the network interface the alias will be configured on.

     The 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 address.

FILES
     /etc/ifaliases, /etc/rc.d/network

HISTORY
     The ifaliases file appeared in NetBSD 1.2.

BUGS
     ifaliases assumes IPv4, and does not support other protocol families.
     Please check rc.conf(5) for alternatives like /etc/ifconfig.xxN.
