There is a much cheaper and effective way to support multiple IP addresses
per interface: number and bit mask, e.g.
ifconfig le0 ipaddr 220.127.116.11 hostmask 0.0.0.15
for this example, the host would accept 18.104.22.168 through 22.214.171.124, and
it would only cost you a mask & compare to implement. Granted, this only
works for ranges of addresses, but given how cheap this can be, and that
you can easily assign ranges of addresses on a single network...
just a thought,
