We should not make such assumptions. I have already seen hosts
configuring many global addresses.
You are right of course. We shouldn't assume this, and it was in no way
my intention to say the number of addresses _should_ be just two. It's
just that the address selection problem is complex and having very many
addresses really doesn't help. Removing known low quality addresses is
the easiest way to optimize this.
You have also to consider things like
privacy extensions and temporary addresses -- addresses which, by the
way, should never be placed in a database...
Yes. However, for the purposes of what we're trying to do we can
usually aggregate different addresses with the same prefix and treat
them as one address for optimization purposes.
