Mathematical Proof Reveals How To Make The Internet More Earthquake-Proof

Posted March 5th, 2014


From MIT Technology Review

Decentralized networks are naturally robust against certain types of attack. Now one mathematician says advanced geometry shows how to make them even more robust.

One of the common myths about the internet is that it was originally designed during the Cold War to survive nuclear attack. Historians of the internet are quick to point out that this was not at all one of the design goals of the early network, although the decentralized nature of the system turns out to make it much more robust than any kind of centralized network.

The Skinny on IPv6

Posted October 18th, 2013


From AZZURI DOT ORG

So what is IPv6, and why do I need to know about it?

IPv6 or IP version 6 is the next generation Internet protocol which will eventually replace the current protocol IPv4. IPv6 has a number of improvements and simplifications when compared to IPv4. The primary difference is that IPv6 uses 128 bit addresses as compared to the 32 bit addresses used with IPv4. This means that there are more available IP addresses using IPv6 than are available with IPv4 alone. For a very clear comparison, in IPv4 there is a total of 4,294,967,296 IP addresses. With IPv6, there is a total of 18,446,744,073,709,551,616 IP addresses in a single /64 allocation.

To also help illustrate the sheer magnitude of available IP addresses using IPv6, you can get 65536 /64 allocations out of a single /48, and then 65536 /48 allocations out of a single /32. Many Service Providers are getting /32 allocations from their Regional Internet Registry (RIR) like ARIN, APNIC, RIPE, etc.

A significant difference between IPv6 and IPv4 is the address notation. IPv4 uses a period (.) between each octet, compared to IPv6 which uses a colon (:). With IPv6, if you have a series of zeroes in a row, the address need not be written out completely. You can use a double colon (::) to represent that series of zeroes, however you can only use that once. For example, if you have an address like “2001:0DB8:0000:0003:0000:01FF:0000:002E”, it can be written like “2001:DB8::3:0:1FF:0:2E” or “2001:DB8:0:3:0:1FF::2E”, but would never be written like “2001:DB8::3::1ff::2E”. You also cannot have three colons in a row (:::).

IPv6 availability depends on your Service Provider, either at home or for work. In a dual-stack environment, IPv4 and IPv6 co-exist along the same connection and don’t require any special kind of connection. If dual-stack is not available, you might find yourself using an IP tunneling product or service to bring IPv6 connectivity to you. Even though IPv4 exhaustion has happened at IANA, IPv4 won’t simply disappear off the face of the Internet, but continued explosive growth requiring more unique IP address assignments will mean using more and more of the abundant IPv6 address space.

Many Operating System platforms have native IPv6 support these days. The UNIX based platforms like Linux, BSD (Free, Open, Net) & MacOSX have had IPv6 support enabled for years now. Microsoft Windows starting having native IPv6 support enabled by default with its Vista and Windows 2008 products. Earlier Windows versions like 2000/2003/XP had to have it installed optionally, and did not have as robust features that are available in the newer versions of Windows. Even common web browsing and email software will use IPv6 if it is enabled and available, without having to check off an option or special configuration. The transition from IPv4 to IPv6 is being worked on to be as seamless as possible, and many might not even notice the subtle changes in the coming years.

Agreement Signed to Expand L-Root Servers Across Africa

Posted October 19th, 2012


From ICANN News & Press

ICANN and the Africa Network Information Center (AFRINIC) have signed an agreement pledging to work collaboratively to identify additional potential locations for the expansion of L-Root anycast instances in Africa.

The placement of instances of root servers is important to the infrastructure of the Internet in Africa.

“This agreement comes in at a perfect time here in Toronto when ICANN has unveiled a new initiative to increase presence and participation across our region” said Adiel Akplogan, AFRINIC’s Chief Executive Officer. “Besides policy related discussions and participation, Africa needs to strengthen the resiliency of its Internet Infrastructure in order to attract local contents investments.”

“This very important agreement is a further reflection of the hard work of the Africa stakeholders and their spirit of engagement” said Fadi Chehadé, President and Chief Executive Officer of ICANN. “Our commitment to this sort of cooperative effort is framed by the initiative of the Africa Support Working Group, which is aimed at increasing African participation in ICANN.”

The Africa Support Working Group presented its three year initiative during ICANN‘s 45th public meeting in Toronto, Canada. The agreement between AfriNIC and ICANN marks the first implementation of the Africa Strategy.

Under the signed agreement, AFRINIC is willing to help ICANN strengthen the resilience of the DNS further by helping to identify potential additional physical locations that host L-Root.

Internet powers flip the IPv6 switch

Posted June 4th, 2012


From CNET

The time for testing is over as Facebook, Cisco, Comcast, and others will soon permanently enable next-generation Internet technology with vastly more elbow room. What’s it all mean?

What began as a 24-hour test a year ago will become business as usual on Wednesday as a range of big-name Internet companies permanently switch on the next-generation IPv6 networking technology.

And now there’s no turning back.

“IPv6 is being enabled and kept on by more than 1,500 Web sites and ISPs in 22 countries,” said Arbor Networks, a company that monitors global Internet traffic closely.

Internet Protocol version 6 has one big improvement over the prevailing IPv4 standard it’s designed to supplant: room to grow. However, moving to IPv6 isn’t simple, which is why many organizations on the Internet have banded together for Wednesday’s World IPv6 Launch event overseen by a standards and advocacy group called the Internet Society.

IBM Busts Record for ‘Superconducting’ Quantum Computer

Posted February 29th, 2012


From WIRED

Today’s quantum computers are no more than experiments. Researchers can string together a handful of quantum bits — seemingly magical bits that store a “1″ and “0″ at the same time — and these ephemeral creations can run relatively simple algorithms. But new research from IBM indicates that far more complex quantum computers aren’t that far away.

On Tuesday, IBM revealed that physicists at its Watson Research Center in Yorktown Heights, New York have made significant advances in the creation of “superconducting qubits,” one of several research fields that could eventually lead to a quantum computer that’s exponentially more powerful than today’s classical computers.

According to Matthias Steffen — who oversees Big Blue’s experimental quantum computing group — he and his team have improved the performance of superconducting qubits by a factor of two to four. “What this means is that we can really start thinking about much larger systems,” he tells Wired, “putting several of these quantum bits together and performing much larger error correction.”

Robot bee assembles in pop-up origami trick

Posted February 27th, 2012


From CNET

Army-funded researchers at the Harvard Microrobotics Laboratory are popping out Harvard Monolithic Bees (“Mobees”) from multi-layered, laser-cut blocks about the size of a quarter.

Inspired by pop-up books, the manufacturing process could allow for rapid production of dozens of flying robots and other electromechanical devices. The research is being published in the March edition of the Journal of Micromechanics and Microengineering.

In the RoboBees project, Pratheev Sreetharan and colleagues want to build bee-size robots that can fly and act autonomously as a colony. Until recently, it used a painstaking manual assembly method.

Apple tactics in China iPad deal unusual: experts

Posted February 27th, 2012


From Reuters

Proview Electronics, the firm trying to stop Apple Inc from using the iPad name in China, has a plausible claim over the unusual methods Apple used to conceal its identity when attempting to acquire Proview’s trademarks, according to several legal experts.

But Apple also has some strong defenses against a lawsuit Proview filed last week in California – including the argument that Proview cannot sue Apple, but can only sue the corporation that actually bought the trademarks, the experts said.

“UN Expert Urges Governments To Ensure Free Flow of Information On Internet”

Posted October 25th, 2011


As posted to Un.org: “21 October 2011 – An independent United Nations human rights expert today urged Governments to ensure that the Internet is made widely available, accessible and affordable to all, and to guarantee the free flow of information online.

“Governments are using increasingly sophisticated technologies and tactics which are often hidden from the public to censor online content and to monitor and identify individuals who disseminate critical or sensitive information,” says Frank La Rue, the Special Rapporteur on freedom of expression.”

“Who Should Run The Internet?”

Posted October 3rd, 2011


The Economist.com weighs in on Internet governance:

“NETHEADS build, run and protect the internet. They often profit from it too. More than 2,000 of them from more than 100 countries descended on Nairobi this week for the latest Internet Governance Forum (IGF), a conference organised under United Nations auspices. The ponderous official theme was the internet “as a catalyst for change”, with a lot of nodding to WikiLeaks and the Arab spring. The reality outside the conference hall, the UN headquarters in the Kenyan capital, was more striking. Kenyans nowadays often go online on their mobile phones. Surfing the web is getting faster and cheaper by the day. The internet is no longer a geeks’ affair in the rich world, but woven into the fabric of business and life even in the poor one.

The IGF is not a typical UN meeting with a carefully staged agenda and much diplomatic protocol. All participants had the same right to take the floor. Government suits had to listen patiently to the complaints of internet activists. And the end of the shindig was not marked by a finely tuned communiqué, but by a workshop dedicated to what the organisers should do better.

All this makes the IGF an unusual grouping. It is in effect a poster child for what insiders like to call the “multi-stakeholder” model. All involved have a say and decisions are taken by “rough consensus”. This approach has worked for the internet so far, but it is increasingly under attack. Governments now want to be given the last word on contentious issues rather than being merely treated as just another stakeholder.”

“Al Gore gives way to Mikhail Gorbachev for control of .eco domain”

Posted September 30th, 2011


As reported by Guardian.co.uk: “A bid by an Al Gore-backed consortium to control a major new “green” web domain has been dropped, paving the way for a rival pitch by an organisation supported by Mikhail Gorbachev.

The global power struggle, with echoes of the cold war, is over control of the new .eco internet domain which could be up and running by 2013. This is one of hundreds of new top level domains (TLDs) set to be created soon, meaning that .guardian, .nyc and .bank could soon join the existing 22 suffixes including the more familiar .com and .net (which are separate of the country-specific domain endings such as .uk), following a decision by the internet regulator Icann in June 2011.”
