Internet of Everything Cisco defines the Internet of Everything (IoE) as bringing together people, process, data, and things to make networked connections more relevant and valuable than ever before. Cisco estimates that there will be 50 billion “connected” devices by 2020. That’s a lot of addresses!
No more NAT as we know it Using NAT to “hide” IPv6 networks has been the source of some debate. IETF continues to state that NAT is not a security feature. NAT for IPv4 breaks many things. IETF does not support the concept of translating a “private IPv6” address to a “public” IPv6 address... but there are exceptions. 192.168.1.0/24 RFC 1918 Private Address Public IPv4 Address NAT
Benefits of IPv6 Larger address space Stateless autoconfiguration End-to-end reachability without private addresses and NAT Better mobility support Peer-to-peer networking easier to create and maintain, and services such as VoIP and Quality of Service (QoS) become more robust. The “killer application” for the Internet is the Internet itself.
