Re: Number of addresses

There is an additional risk to mention, strictly related to limitation of IP addresses. Set of home devices interconnected to Internet by using only one address (as per mostly configuration deployed), increases a lot the risk of contamination of the whole set, by only one un-secure action. Then, to avoid huge risk as per example mentioned, the migration to IPv6 should appear more safety.

Re: Avoiding NAT, allowing p2p

Exactly Cryptoman, good point; by eliminating NAT, full visibility among users' devices is deployed by adopting IPv6. As natural step no limitation in peering for allowing any-to-any interaction !

Number of IPv6 addresses = 3.4 x 10^38

Just a quick note of correction: the definition on the Internet Society page is based on IPv4, which supports 32 bit addresses. The key advantage of IPv6 is that it supports 128 bit addresses and therefore provides a much larger pool of available device addresses compared to IPv4.

IPv6 is very important in terms of accommodating vastly more devices and users on the internet as well as providing greater flexibility in allocating addresses and efficiency for routing traffic. IPv6 will also eliminate the need for "Network Address Translation" (NAT) that was widely used to avoid IPv4 address exhaustion.

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.

You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically. Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions? Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
