1035 One can configure more than one IPv4 address with the
1036 .Va ipv4_addrs_ Ns Aq Ar interface
1038 One or more IP addresses must be provided in Classless Inter-Domain
1039 Routing (CIDR) address notation, whose last byte can be a range like
1041 In this case the address 192.168.0.5 will be configured with the
1042 netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
1043 the non-conflicting netmask /32 as explained in the
1046 With the interface in question being
1048 an example could look like:
1050 ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
1053 It is also possible to add IP alias entries using
1056 Assuming that the interface in question was
1059 something like this:
1061 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
1062 ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"

1077 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
1080 Then note that alias4 would
1082 be added since the search would

1113 It is possible to bring up an interface with DHCP by adding
1116 .Va ifconfig_ Ns Aq Ar interface

1126 Also, if you want to configure your wireless interface with
1127 .Xr wpa_supplicant 8
1128 for use with WPA, EAP/LEAP or WEP, you need to add
1131 .Va ifconfig_ Ns Aq Ar interface
1134 Finally, you can add
1136 options in this variable, in addition to the
1137 .Pa /etc/start_if. Ns Aq Ar interface
1139 For instance, to initialize the
1141 device via DHCP, using WPA authentication and 802.11b mode, it is
1142 possible to use something like:
1144 ifconfig_wi0="DHCP WPA mode 11b"

1149 form, a fallback variable
1150 .Va ifconfig_DEFAULT
1152 It will be used for all interfaces with no
1153 .Va ifconfig_ Ns Aq Ar interface
1155 This is intended to replace the no longer supported
1159 It is also possible to rename interface by doing:

1162 ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
1164 .It Va ipv6_network_interfaces
1166 This is the IPv6 equivalent of
1167 .Va network_interfaces .
1168 Instead of setting the ifconfig variables as
1169 .Va ifconfig_ Ns Aq Ar interface
1170 they should be set as
1171 .Va ipv6_ifconfig_ Ns Aq Ar interface .
1172 Aliases should be set as
1173 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
1174 .Va ipv6_prefix_ Ns Aq Ar interface
1176 Interfaces that do not have a
1177 .Va ipv6_ifconfig_ Ns Aq Ar interface
1178 setting will be auto configured by
1181 .Va ipv6_gateway_enable
