You can have multiple unique unbonded IP addresses per machine since a machine can have multiple NIC cards installed or built-in, e.g. each Xserve G5 and quadcore tower comes with two ethernet ports which can have at least one unique IP address per port, etc.

I never said that "IP uniqueness has to do with the number of NICS." I said that with multiple NICs in a single machine/host (and aliasing as you have brought up), a machine/host might not have a "unique" IP, even on the common network. Whether this is a good or bad practice is not under debate here.

Actually, that would be two NICs since a host can have multiple NICs as you have agreed. Let's all be "precise" here since you decided to wade into the thick of this...

Once he started added the missing bits in square brackets to his sentence which he originally omitted, that is. He was the one who wanted everybody to be "precise" and I fail to see how he is to be exempt from the standards he insists others follow. Or are you saying that he should be granted divine dispensation for some reason?

Obviously it doesn't feel as good when it's you with the target painted on your pointy little head, isn't it? Look who's calling other people twits...

Throwing that into the mix doesn't answer nor excuse his lack of precision to begin with. A lack of precision which he then corrected and backpedaled on and tried to pass off another's comment on it as "nitpicking". My point is that if he doesn't want to nitpicked, then he should not nitpick others.

Excuse me? He later clarified himself after being imprecise, which he accuses others of being (see the threaded rant that ended with the differences between musk oxen and oxen, etc). Now, if he holds others up to the standards of precision he insists on when posting, then he can damned well follow those same standards he imposes on others. Sauce for the goose is sauce for the gander.
And it is true that I dislike the arrogant and their sycophants. And those who think that they can set standards but consider themselves exempt from those standards. This forum is for *ALL* who have to deal with Mac OS X Servers, not solely for those who [mis]perceive themselves as cognoscenti. If nothing else, those who are truly cognoscenti should have a sense of noblesse oblige and help those with less knowledge rather than belittling them. Otherwise why bother participating in this forum?
