1042 One or more IP addresses must be provided in Classless Inter-Domain

1045 In this case the address 192.168.0.5 will be configured with the
1046 netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
1047 the non-conflicting netmask /32 as explained in the

1052 an example could look like:
1054 ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
1057 It is also possible to add IP alias entries using
1060 Assuming that the interface in question was
1063 something like this:
1065 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"

1136 Finally, you can add
1138 options in this variable, in addition to the
1139 .Pa /etc/start_if. Ns Aq Ar interface
1141 For instance, to initialize the

1151 form, a fallback variable
1152 .Va ifconfig_DEFAULT
1154 It will be used for all interfaces with no

1157 This is intended to replace the no longer supported
1161 It is also possible to rename interface by doing:

1164 ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
1166 .It Va ipv6_network_interfaces
1168 This is the IPv6 equivalent of
1169 .Va network_interfaces .
1170 Instead of setting the ifconfig variables as

1172 they should be set as
1173 .Va ipv6_ifconfig_ Ns Aq Ar interface .
1174 Aliases should be set as
1175 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
1176 .Va ipv6_prefix_ Ns Aq Ar interface
1178 Interfaces that do not have a
