IFALIASES(5) BSD 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 sys-
tem 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.
