Maybe the fact that so may people ask about or are surprised by it is a
sign that it is counter-intuitive and should perhaps be more fully
documented?
The fact that "ifconfig" or "ip addr" show IP addresses as specifically
associated with individual ethernet links may contribute to this
problem--it sure makes it look like the IP address is an attribute of
the link rather than the host.
