Abstract: Network address date groups are defined that are associated with a group of electronic objects. Where network address date groups appear to relate to the same person or group, they are assigned an entity group identifier that allows tracking the electronic objects across network address changes. The entity group identifier may then be used by an advertiser or other service provider.
