1000 One can configure more than one IPv4 address with the
1001 .Va ipv4_addrs_ Ns Aq Ar interface
1003 One or more IP addresses must be provided in Classless Inter-Domain
1004 Routing (CIDR) address notation, whose last byte can be a range like
1006 In this case the address 192.168.0.5 will be configured with the
1007 netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
1008 the non-conflicting netmask /32 as explained in the

1013 an example could look like:
1015 ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
1018 It is also possible to add IP alias entries using

1024 something like this:
1026 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"

1097 Finally, you can add
1099 options in this variable, in addition to the
1100 .Pa /etc/start_if. Ns Aq Ar interface
1102 For instance, to initialize the
1104 device via DHCP, using WPA authentication and 802.11b mode, it is
1105 possible to use something like:
1107 ifconfig_wi0="DHCP WPA mode 11b"

1112 form, a fallback variable
1113 .Va ifconfig_DEFAULT
1115 It will be used for all interfaces with no

1118 This is intended to replace the no longer supported
1122 It is also possible to rename interface by doing:

1127 .It Va ipv6_network_interfaces
1129 This is the IPv6 equivalent of

1133 they should be set as
