Whilst not 100% sure about this, I suspect that this might be caused by our IPv6 Matrix Crawler which we are running pro-bono to track the spread of IPv6 content. Having officially announced some of its results at the conference which was hosted in London by the Internet Society on 29th September 2010, I wanted to announce this here too: ISOC England was awarded a Community Grants Programme award in November 2009, for the design and implementation of an ?IPv6 crawler,? a computer and its software that would crawl through the DNS at pre-set intervals in order to detect, for example, IPv6 DNS servers and IPv6 compliant Web servers, SMTP mailers, and NTP servers. The search for project partners led to a link-up with Nile University (Egypt) where professors and their research assistants got to grips with IPv6, and started the task of writing the software required in the project, as part of their experience. In the meantime, the London team of partners built and installed two servers and a router at Telehouse East, one of the UK's most connected facilities. One server was set-up as a crawler, and one as a Web server and information storage, both connected to the Internet backbone via Dual Stack IPv4/IPv6. The list of domains tested consisted initially of the world's 1 million most popular Web sites, as referenced by alexa.com. After a cleaning up process, about 980 000 domains supported by nearly 5.6 million hosts were tested periodically. Results were surprising, and showed how little dual stack IPv4/IPv6 was supported by major Web sites. Without content, it is no wonder that the current volume of IPv6 traffic on the Internet is so low! The results were saved in text files and SQL databases were created for easy interrogation. The Web site found on: http://www.ipv6matrix.org/ is an example of a front end which interrogates those databases, and displays results using the Google Charts APIs. Ultimately, we plan to document the SQL database structure, so as to allow for other projects to retrieve data directly from the databases. Currently, a full scan of all TLDs in the database takes just over a month, and results are stored for future analysis. It is hoped that a growth trend of IPv6 will be seen in a few months. In the long term, the data collected will enable researchers to find out exactly how major new technologies, such as the migration to IPv6, spread on the Internet, and will answer the questions relating to finding the early and late adopters of new technology. In the short term, the maps show a snapshot of real world IPv6 penetration data at a glance, and detailed results are also made available, helped by a system of user-configured filters. A presentation of the September 2010 data for Europe and Asia was made at the INET London conference, its deck of slides downloadable from: http://www.slideshare.net/ocl999/ipv6-matrix-exec-summary One final note, before you ask: we have received 9 enquiries (out of 980 000 domains) about Firewalls erroneously detecting a port attack of some sort during the scanning process. The only ports which the Crawler tests connectivity to are: - Port 25 (SMTP) - Port 53 (DNS) - Port 80 (HTTP) - Port 443 (HTTPS) - Port 123 (NTP) This generates an insignificant amount of traffic in the order of a few bytes only. Let me make this clear: we are not performing port scans. At this early alpha (or beta) stage, we would look forward to any feedback regarding the data we collect, and for any bugs to be pointed out for the Team to resolve. On the question of accuracy of results, we have found that results are less accurate in TLD sample sizes under 900 domains. Larger TLD sample sizes increase accuracy. We therefore appeal to any Registry whose zone data sample size is less than 1000 domains to contact us, should they wish to provide a wider sample of input domains for the zone they are responsible for.

This morning when I turned it on the computer started hissing and cracking, then started smoking and a bad smell, then nothing'. TECH SUPPORT: 'I will have a technician come over first thing this morning. Leave the computer just like it is, so they can find the problem and fix it, or change it out with another computer. Give me your address; phone number and the technician will be there just as soon as he can'. When the technician got there, the lady showed him where the computer was, said what happened to it, ... this is what the technician found wrong. Take a look at the pictures... YOU WON'T BELIEVE YOUR EYES ... And you thought YOU had computer problems!!! The technician told her: ... 'It must have been after the mouse!' ...
