1039 One can configure more than one IPv4 address with the
1040 .Va ipv4_addrs_ Ns Aq Ar interface
1042 One or more IP addresses must be provided in Classless Inter-Domain
1043 Routing (CIDR) address notation, whose last byte can be a range like
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
1050 With the interface in question being
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"
1066 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

1081 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
1084 Then note that alias4 would
1086 be added since the search would

1130 Also, if you want to configure your wireless interface with
1131 .Xr wpa_supplicant 8
1132 for use with WPA, EAP/LEAP or WEP, you need to add
1135 .Va ifconfig_ Ns Aq Ar interface
1138 Finally, you can add
1140 options in this variable, in addition to the
1141 .Pa /etc/start_if. Ns Aq Ar interface
1143 For instance, to initialize the
1145 device via DHCP, using WPA authentication and 802.11b mode, it is
1146 possible to use something like:
1148 ifconfig_wi0="DHCP WPA mode 11b"

1153 form, a fallback variable
1154 .Va ifconfig_DEFAULT
1156 It will be used for all interfaces with no
1157 .Va ifconfig_ Ns Aq Ar interface
1159 This is intended to replace the no longer supported
1163 It is also possible to rename interface by doing:

1166 ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
1168 .It Va ipv6_network_interfaces
1170 This is the IPv6 equivalent of
1171 .Va network_interfaces .
1172 Instead of setting the ifconfig variables as
1173 .Va ifconfig_ Ns Aq Ar interface
1174 they should be set as
1175 .Va ipv6_ifconfig_ Ns Aq Ar interface .
1176 Aliases should be set as
1177 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
1178 .Va ipv6_prefix_ Ns Aq Ar interface
1180 Interfaces that do not have a
1181 .Va ipv6_ifconfig_ Ns Aq Ar interface
1182 setting will be auto configured by
