IPv6 includes improvements over IPv4 such as a wider range of Internet addresses, improved routing and autoconfiguration, embedded encryption, and more. Not all operating systems and applications can utilize IPv6; however, new software is slowly making the transition. On June 6, 2012, Google and several thousand other companies migrated to IPv6. Since then, more companies have updated their services and products as well.
