Not if you are running pure IP. Either you can uniquely identify each
machine,
or you can't, but you cannot have it both ways.
Nor did I say you could. The point is that how IP addresses are used varies. If
you want to use IP address to uniquely identify your systems you can. And
someone else can use a single IP address to refer to multiple systems. As
long as people are clear on what they are doing and don't assume what
they do applies to others there's no conflict.
Why is this so hard for you to understand?
