Hi there :)
You need to:
(a) use netmask 0xffffffff
(b) place entries in rc.conf for your aliases. rc.conf already has
functionality for you to do this. For example, here is a segment of my
rc.conf:
# primary address
ifconfig_xl0="inet 10.0.0.2 netmask 0xffffff00"
# aliases
ifconfig_xl0_alias0="inet 10.0.0.10 netmask 0xffffffff"
ifconfig_xl0_alias1="inet 10.0.0.11 netmask 0xffffffff"
ifconfig_xl0_alias2="inet 10.0.0.12 netmask 0xffffffff"
Hope I helped some ;)
