Actually, I think I probably said something as follows: If we define 'locator' is a 'internetwork-level location-sensitive name for an interface', then one obvious design option for a 'full' locator, for the typical Ethernet interface, is some sort of hierarchical name for the physical network (i.e. subnet), with the MAC address appended. In other words, an IEEE MAC address is *part* of a locator (if you are defining 'locator' to be 'internetwork-level location-sensitive name for an interface'). Yes, if you plug that interface in somewhere else, the locator changes - but the low-order part (the MAC address) will be the same. Similarly, because to me a 'locator' is the name of an interface, the MAC address (or something that maps to it, as in IPv4) would have to be part of the locator. Does that make sense? > I am pretty confused at this point about what your perspective is. I > gather your thinking has evolved since this precise question last came > up. No, not really. The things I think have changed are that i) I'm more sensitive now to understanding how all these terms (e.g. "locator") all mean different things to different people, and ii) I'm slowly becoming more precise (with all these different axes of name attributes: locationality, level, object, etc) about the taxonomy of names.
