Are IP addresses based on location?
Voice over IP
In IP telephony, no such direct link between location and communications end point exists. Even a provider having hardware infrastructure, such as a DSL provider, may know only the approximate location of the device, based on the IP address allocated to the network router and the known service address. Some ISPs do not track the automatic assignment of IP addresses to customer equipment.
IP address
Early practices used a different block for this purpose (), dubbed site-local addresses. However, the definition of what constituted a "site" remained unclear and the poorly-defined addressing policy created ambiguities for routing. This address type was abandoned and must not be used in new systems.
