1073 variable is also assumed to exist for each value of

1087 One can configure more than one IPv4 address with the

1090 One or more IP addresses must be provided in Classless Inter-Domain
1091 Routing (CIDR) address notation, whose last byte can be a range like
1093 In this case the address 192.168.0.5 will be configured with the
1094 netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
1095 the non-conflicting netmask /32 as explained in the

1100 an example could look like:

1111 something like this:
1113 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"

1129 ifconfig_ed0_alias4="inet 127.0.0.254 netmask 0xffffffff"
1132 Then note that alias4 would
1134 be added since the search would
1135 stop with the missing

1185 It is possible to bring up an interface with DHCP by adding
1188 .Va ifconfig_ Ns Aq Ar interface
1190 For instance, to initialize the

1198 Also, if you want to configure your wireless interface with
1199 .Xr wpa_supplicant 8
1200 for use with WPA, EAP/LEAP or WEP, you need to add
1203 .Va ifconfig_ Ns Aq Ar interface
1206 Finally, you can add
1208 options in this variable, in addition to the
1209 .Pa /etc/start_if. Ns Aq Ar interface
1211 For instance, configure an
1213 wireless device in station mode with an address obtained
1214 via DHCP, using WPA authentication and 802.11b mode, it is
1215 possible to use something like:
1218 ifconfig_wlan0="DHCP WPA mode 11b"

1223 form, a fallback variable
1224 .Va ifconfig_DEFAULT
1226 It will be used for all interfaces with no

1229 This is intended to replace the no longer supported
1233 It is also possible to rename interface by doing:

1236 ifconfig_net0="inet 10.0.0.1 netmask 0xffff0000"
1238 .It Va ipv6_network_interfaces
1240 This is the IPv6 equivalent of
1241 .Va network_interfaces .
1242 Instead of setting the ifconfig variables as

1244 they should be set as

1246 Aliases should be set as
