rc.conf config more than one IP address on one interface

the best way to configure more than one IP to one interface in freebsd is to edit /etc/rc.conf

ipv4_addrs_vr0="192.168.0.1/24 192.168.1.1-5/28" #I prefer this way


It is also possible to add IP alias entries using ifconfig(8) syntax. Assuming that the interface in question was ed0, it might look something like this:

ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"
ifconfig_ed0_alias1="inet 127.0.0.254 netmask 0xffffffff"
