locator A locator is a name that has topological sensitivity and

A locator is defined as a designator which has topological
significance and provides reachability information for endpoints; the
locator(s) associated with an endpoint change if/when the point(s) of
attachment of an endpoint within the network topology changes.
identifier An identifier is the name of an endpoint. It has no
topological sensitivity. That is, the identifier will not
change, even if the endpoint changes its attachment within
the topology. Identifiers may have other properties, such
as the scope of their uniqueness (global or local) and the
probability of their uniqueness (absolute or statistical).
An identifier is the designator of an endpoint; identifiers have no
topological significance, and do not change even if the endpoint
changes its point(s) of attachment within the network topology.
Identifiers may exhibit other properties such as global uniqueness,
local uniqueness (for varying definitions of 'local'), absolute
uniqueness, statistical probability of uniqueness, etc.
address An address is a name that is both a locator and an
identifier.
An address is a designator which conflates the properties of a locator
with the properties of an identifier.
