Problem Statement The Internet is running out of IPv4 addresses The “Internet” edges are IPv4 Most hosts in the home today (Win 9.x, XP,…) are IPv4 and will never be upgraded to work in an IPv6-only environment content servers (Web, Mail,…) hosted by many different parties will take a long time to upgrade to IPv6 Service providers are in between the plumbing in the middle may be the “easier” part to fix first |
