Network World: Researchers ping through first full “Internet Census” in 25 years.
Over two months, researchers at the Information Sciences Institute pinged (pung?) every IP address in IPv4. Even more interesting:
These addresses appear in the chart as a grid of squares, each square representing all the addresses beginning with the same first number (“128,” in the preceding example). The map is arranged in ascending numerical order, but instead in a looping pattern called a Hilbert curve, which keeps adjacent addresses physically near each other, on chart,” but also makes it possible to zoom seamlessly in to show greater detail. “The idea of using a Hilbert curve actually came from a web comic, xkcd,” said Heidemann.
The process took 62 days. A similar census of the IPv6 ranges would, if my math is right, take 40,483 years and 41 days. Hmm, there’s got to be a better way to figure out IPv6…
Ordigami: IPv6 in Origami.
Conservative estimates on deployment imply that there will be about 2000 addresses for each square meter of the Earth’s surface. To illustrate that, Etienne Cliquet created an origami sheet one meter square, with 2000 triangles on it – one for every IP address in that theoretical meter.
Beskerming.com: The difference between theory and practice.
McAfee recently put out a study that while 90% of users believe they’re using up-to-date Antivirus software, only 51% actually were.
While the figures demonstrate an increase in the percentage of users over the last three years who believe that they are maintaining up-to-date antivirus protection (weekly or daily updating), the percentage of users who are not actually running any protection (or maintaining protection at the level they think they are) have been dropping a lot slower than the first set of figures would suggest. With more than 90% of respondents indicating that they were maintaining daily / weekly coverage from their antivirus software, it might be somewhat of a surprise to see that 49% of respondents were actually not running any antivirus software, or antivirus software that was not updating definitions on a daily or weekly basis.
Of course, there are those smug guys who will point out that this is mainly a Windows problem…
Slashdot Firehose: Do Content Provider Executives Read Online Forums?
This was a question submitted to Ask Slashdot – it wasn’t picked up, but it’s still a good question.
Given the hundreds — if not thousands — of submissions to slashdot, digg, techdirt, et al regarding DRM and all of its catastrophic failures (let’s use Blu-Ray and HD-DVD as the main example), do the decision makers and visionaries at these companies put any stock into the horribly negative feedback all over the web concerning these topics?
The cynic answers: “No, what does Joe CIO care about some Internet portal?” But is that being too cynical? Does online commentary and popular opinion online matter?
