IPv4 Address Market Takes Off

count.dat2-3

As the available supply of IPv4 addresses dwindles, the market for these virtual commodities is heating up.  In recent months, the pace of the address transfers has greatly accelerated as evidenced by RIPE’s table of IPv4 transfers, as well as the increasing number of IPv4 brokers facilitating the exchange of IPv4 address space.  However, the transfer of IPv4 address space isn’t always problem-free and, in this blog, we’ll review this new trend and some of the issues that can arise.

Buying and selling IPv4

In 2011, when Microsoft paid $7.5 million for 666,624 IPv4 addresses as part of the Nortel bankruptcy, observers wondered whether this development would usher in the era of the commercial sale of IPv4 address space.  As statistics from European registrar RIPE show, the market may have had a slow start, but we’re in that new era now.

RIPE’s table of transfers of provider independent IPv4 address clearly shows a rapidly increasing rate of transfers of IPv4 address blocks and unique IPv4 addresses.  The following two graphs illustrate the uptick in recent months of address space movement.  February 2015 saw that most organizational transfers (373), while November 2014 saw the Continue reading

Acer’s Revo One RL85 desktop comes to US with Broadwell chips

Acer isn’t as well known as Apple for product design, but its new Revo One RL85 compact desktop looks dapper—and with Intel’s latest Broadwell chip it also has muscles.The multifaceted desktop can be a PC, but it also can sit in a corner and serve as a media player or be used for backup storage. The desktop is now available in the U.S., and starts at US$249.99 with Intel’s entry-level Celeron processors, and at $479.99 with Intel’s Core i3 chips code-named Broadwell.With its unorthodox design, the Revo One RL85 stands out from today’s mundane beige boxes. Its sharp finish resembles a smaller version of a Kenmore bread maker, but it looks attractive nonetheless. It is just 15.5 centimeters tall.To read this article in full or to leave a comment, please click here

You’ve seen Apple logo a million times, but what’s it look like?

UCLA Actual Apple logo? None of the above Even Apple fanboys and fangirls might be sick of seeing the company's logo, but that doesn't mean they actually would remember exactly what it looks like when pressed. In a new study published in the Quarterly Journal of Experimental Psychology, UCLA psychologists found that only 1 of 85 undergraduates could draw the logo correctly from memory.  Fewer than half correctly ID'd the logo when shown it among a number of similar logos. Most of the participants used Apple products.To read this article in full or to leave a comment, please click here

Microsoft gives one of Windows Phone’s best features to iOS, Android

Windows Phone is not setting the world on fire, which means that only about 3% of all mobile phone users even know about some of its cool features. Rather than keep those features to itself, Microsoft is making them available to other platforms.The company has announced that Office Lens, its photo scanning app that crops pictures and automatically drops them into OneNote or Onedrive, is available for free at Apple's App Store, and that the Office Lens Android Preview is available for testing.The idea behind Office Lens is comparable to the Scannable feature in Evernote. It lets you take a quick picture of a whiteboard, receipt, billboard, or anything else similar and quickly scan and save it to a storage service. The app will auto-crop receipts, whiteboards, and anything else where there is a white object against a dark background.To read this article in full or to leave a comment, please click here

Vulnerable Dell support tool now detected as risky software

Security vendor Malwarebytes has flagged the Dell System Detect tool as a potentially unwanted application after older versions of the program were found to put computers at risk.Last month a security researcher named Tom Forbes warned that attackers can exploit a weakness in older versions of Dell System Detect to remotely install malware on computers when users visit specially crafted websites.The program allows Dell’s support website to automatically detect the service tags of users’ PCs, so it can offer the corresponding drivers. The tool is offered for download when users click the “Detect Product” button on the website for the first time and continues to run in the background after installation.To read this article in full or to leave a comment, please click here

The best way to stop DDoS attacks

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

Experiencing a distributed denial-of-service (DDoS) attack is like having your home flood. Without warning, attackers can upend your enterprise. Every moment counts, but unfortunately by the time some DDoS solutions identify and report the attack, the damage is already done. You need a faster, more immediate means of threat detection to prevent severe damage. 

When a DDoS attack hits your network, a long time can pass before the security/network staff fully realizes it is actually a DDoS attack that is affecting the services, and not a failing server or application. Even more time may pass before the actual mitigation of the threat starts to take effect.

The Upload: Your tech news briefing for Monday, April 6

Camera chip could turn phones into 3D scannersCaltech researchers have developed a camera chip that could let you use your smartphone to take 3D scans of an object, then send the results to a 3D printer to duplicate the thing. The device works by shining perfectly aligned beams of light on a targeted object. It detects subtle differences in the light that is reflected back from that object and uses those differences to build a digital 3D image.U.S.—and IBM—are surging in mobile patents raceThe days are gone when the U.S. was the notable laggard behind Europe in mobile technology: a new report on mobile patents won last year show a sizable increase in the U.S. but a decrease in Europe. And while Samsung still has the biggest mobile patent portfolio, IBM is gaining on it with the most new mobile patentTo read this article in full or to leave a comment, please click here

Camera chip could turn phones into 3D scanners

U.S. researchers have developed a camera chip that could give smartphones the ability to take 3D scans of everyday objects, a sought-after feature in the 3D-printing world.Engineers at the California Institute of Technology (Caltech) said their device is based on a cheap silicon chip less than 1 millimeter square and it can produce 3D scans with extremely fine resolution.The chips could be incorporated into phones and the data could be sent to 3D printers to duplicate scanned objects, eliminating the need to use large desktop devices.To read this article in full or to leave a comment, please click here
