We are in the midst of tremendous growth of IP content sourced from devices within the home. Improved (faster, higher capacity and more feature rich) networked media storage, networked video cameras, and a range of sensors for security, energy management and home health care are all becoming readily available for the residential market.

  • 1. IPv6 in the Connected Home by Thomas Herbst home router. While it is possible to make this home content available, it is compli- cated and error prone. The IETF’s Interac- tive Connectivity Establishment (ICE) effort does help this in some cases. Another complication is that mobile phones often connect to the local network inside the NAT while at home, and then later connect to that same content from the outside. It is confusing that the same content will need to be located by different names or addresses. Pundit predictions of IPv4 address exhaus- Figure 12 - Current IPv4 Environment tion range across the next several years.
