The Internet Society has announced the world launch of IPv6, which will dramatically expand the number of Internet addresses.  IPv6 creates fixed IP addresses, allowing routine tracking of Internet-connected devices, such as laptops, cellphones, and soon many consumer appliances.  This will make it easier for law enforcement agencies and advertisers to track users of Internet-based services.  A Privacy Extension allows the use of IPv6 without persistent identifiers, though it is not clear how widely it will be be adopted.  In 2008, EPIC testified before the European Parliament on IP addresses and privacy, and said that companies that use IPv6 linked to identifiable users should be subject to data privacy requirements.  The EU classifies IP addresses as personal information.  For more information: See EPIC: Search Engine Privacy.
