ZigBee IP spec goes public, offers open IPv6 mesh networking

While ZigBee hasn't become as ubiquitous in wireless as the likes of Bluetooth or WiFi, it has carved out niches in home automation and low-power gear. The format is about to expand its world a little further now that a more network-savvy spec, ZigBee IP, is officially available for everyone. The upgrade adds IPv6 and tougher security to the open mesh networking formula, letting it more easily join an internet of things where there's potentially billions of connected devices. The ZigBee Alliance isn't naming customers at this stage, although it's quick to note that ZigBee IP was built for smart grid use: don't be surprised if you first see it behind the scenes, keeping energy use in check.

China’s new internet backbone explained: verified sources, IPv6 at the core

China's new internet backbone detailed for the public verified sources, IPv6 at the core

While most of the world is still coming to grips with malware and weaning itself off of IPv4, we're just learning that China has been thinking further ahead. A newly publicized US Navy report reveals that China's new internet backbone revolves around an IPv6-based architecture that leans on Source Address Validation Architecture, or SAVA. The technique creates a catalog of known good matches between computers and their IP addresses, and blocks traffic when there's a clear discrepancy. The method could curb attempts to spread malware through spoofing and tackle some outbreaks automatically -- and, perhaps not so coincidentally, complicate any leaps over the Great Firewall. Even with the existence of that potential curb on civil liberties, the improved backbone could still keep network addresses and security under reasonable control when China expects that over 70 percent of its many, many homes will have broadband in the near future.

RIPE NCC handing out its last block of IPv4 addresses, tries to fend off internet survivalism

Europe's RIPE NCC handing out its last block of IPv4 addresses, tries to fend off internet survivalism

In a world where IPv6 lives and IPv4 addresses are scarce, network providers must fight for survival... or at least, claim their IP blocks quickly. The RIPE NCC, the regional internet registry for Asia, Europe and the Middle East, warns that it's down to assigning its last set of 16.8 million IPv4 addresses as of this weekend. That sounds like a lot, but we'd do well to remember that the registry churned through about 5.2 million addresses in just the past two weeks. What's left won't be around for long, folks. To cut back on the number of Mad Max-style battles for dwindling resources, RIPE NCC is rationing out IPv4 for local registries in 1,024-address chunks -- and only to those who both have IPv6 assignments as well as proof of a need for IPv4. With just a bit more than half of the RIPE NCC's customers currently on IPv6, that could still trigger a shortfall among networks that haven't prepared for the internet protocol apocalypse. We'd advise that companies stock up on IPv6 supplies before launching the raiding parties.

IPv6 lands today, do you copy?

IPv6 lands today, do you copy

June 6th has arrived, which means that participating ISPs, hardware manufacturers and search engines must stick to their word and permanently enable the IPv6 address system -- not least as an encouragement for others to do the same. The ultimate purpose? To allow trillions of users to have their own IP address, instead of just a paltry few billion permitted by the IPv4 standard that continues to run in parallel. The risk? That the Internet collapses and we all get the day off work. Evidently that hasn't happened, no doubt thanks to Google and others having tested the system during pilot programs, and indeed Vint Cerf's explanatory video seems to be working fine after the break.
