No, I wouldn't answer that, because there is no such thing as a primary IP. ?All IPs on an interface are equal. ?The term alias exists only for historical reasons, and it's clearly becoming obsolete.
my dear friend I really do not know why you insist on writing this again and again. Firstable it is wrong what you say. IP Aliasing is a correct and perfect term, used since it is possible to set more then one IP and people use it all over the world, in simple networks and specially in hosting environments. So it probably never will become obsolete because firstable it is THE word in use everywhere, it is grammatically correct and it is easy to understand.
It does not exist for historical reasons. It is part of IP history and an important one, exist because it is in use and so it will stay with us - in all OSs ... and almost all languages it is understood as it is - perfectly by definition.
The only correct thing you say here is that all IPs are equal - and - nobody EVER said something different.
Aliasing does not say anything about priority of the Ip it is simply related to the time the interface was set with the IP so the first IP is the one which was set first and the first alias is the one which was set after.
So by common sense alias describes an additional IP address which was add to an already existent address. Otherwise it would not be an alias.
This understanding, which is completely correct, makes it wrong that "ifconfig nic -alias" removes an IP address which is unique on this interface. At least when done without warning.
And also makes it wrong to remove the IP which was set first on this interface since it is not an alias by common understanding even if it is equal in technical functions.
Then, at the end it is perfectly ok when people say primary address because it might be for them THE address of THEIR machine. This is manner of speaking and they are probably fully aware of that the other IPs are equal.
And so this must be bethought, you can not run against common sense even if there might be something not exactly expressed. By all respect, you are running against the wall here.
