- Add CIDR notation support like 192.168.1-2.10-16/24 to $ifconfig_IF_aliasN.
This is an extended version of ipv4_addr_IF which supports both IPv4 and IPv6, and multiple range specifications. To avoid to generate too many addresses, the maximum number of the generated addresses is currently limited to 31. - Add $ifconfig_IF_aliases, which accepts multiple IP aliases in a variable. - ipv6_prefix_IF now supports !/64 prefix length. In addition to the old 64-bit format (2001:db8:1:1), a full 128-bit format like 2001:db8:1:1::/64 is supported. - Replace ifconfig command with $IFCONFIG_CMD variable to support a dry-run mode in the future. - Remove IP aliases before removing all of IPv4 addresses when doing "rc.d/netif down". - Add a DAD wait to network6_getladdr() because it is possible to fail to configure an EUI64 address when ipv6_prefix_IF is specified. A summary of the supported ifconfig_* variables is as follows: # IPv4 configuration. ifconfig_em0="inet 192.168.0.1" # IPv6 configuration. ifconfig_em0_ipv6="inet6 2001:db8::1/64" # IPv4 address range spec. Now deprecated. ipv4_addr_em0="10.2.1.1-10" # IPv6 alias. ifconfig_em0_alias0="inet6 2001:db8:5::1 prefixlen 70" # IPv4 alias. ifconfig_em0_alias1="inet 10.2.2.1/24" # IPv4 alias with range spec w/o AF keyword (backward compat). ifconfig_em0_alias2="10.3.1.1-10/32" # IPv6 alias with range spec. ifconfig_em0_alias3="inet6 2001:db8:20-2f::1/64" # ifconfig_IF_aliases is just like ifconfig_IF_aliasN. ifconfig_em0_aliases="inet 10.3.3.201-204/24 inet6 2001:db8:210-213::1/64 inet 10.1.1.1/24" # IPv6 alias (backward compat) ipv6_ifconfig_em0_alias0="inet6 2001:db8:f::1/64" # IPv6 alias w/o AF keyword (backward compat) ipv6_ifconfig_em0_alias1="2001:db8:f:1::1/64" # IPv6 prefix. ipv6_prefix_em0="2001:db8::/64" Tested by: Kimmo Paasiala

One can configure more than one IPv4 address with the
