• We’re using pretty much all of them (for the first time in about 30 years)

Future Growth Challenges With IPv4
• Subtended NATs • Short IP Leases
• Tunnels and Overlays • Global routing table growth
• Buying/Selling IP address space • Less IP aggregation
• Camping on bogon IP space • Application-Level Gateways
• Reviving 240 reserved space • Shared-SP IPv4 space

IPv6
Summary IP is the fundamental building block of the Internet. IPv4 has been so successful, it is facing scaling challenges due to IPv4 address scarcity. IPv6 is the next version of IP. After more than a decade of preparation, the transition from IPv4 and IPv6 began in earnest in June 2011 with the World IPv6 Day and World IPv6 Launch. Global IPv6 adoption has been doubling every 9 months since. If the trend continues, global IPv6 traffic will eclipse IPv4 within 3-5 years. IoT standards such as 6lowpan, RPL, CoAP, and others are based on IPv6 from day one. IPv6 is not only about more devices, it is a fundamental upgrade to the kind of information we can carry in IP. We are seeing IPv6-based innovation not only in IoT, but in home network technology, core routing, and IPv6-only data centers. The Human Internet is in transition to IPv6, The Internet of Things is Coming, when the two meet we will have the IPv6 Internet of Everything. IPv6 is setting the stage for IoE.
