Right, and the bad thing is if yu alias another IP on that device, the

But didn't you say that you effectively wipe the database once a month,
(or expire entries over that age)? I can't find the post that mentioned
that now, naturally... :-) if you aren't using the 'key' as a database
key, then what do you care that it changes as long as it uniquely
identifies the system (which it definitely would)?

I don't know how typical I am, but I don't really remember the last time
I added an IP alias on a running server, for our few dozen production
systems. I would imagine that those types of changes might well be lost
of systems coming and going.

I add/remove IPs from our servers several times each week, as we add VPS and remove them, or move then between boxes ...
