John Hessler, a member of the US Library of Congress’ Geography and Map Division wrote a nice blog post about our IPv4 Internet maps: “Computing Space V: Mapping the Web or Pinging your Way to Infinity“. Check out his take on our IPv4 data!
You too can browse the IPv4 Internet at our website. Or for detailed analysis, get the data from IMPACT or us.
Thanks to the DHS IMPACT program for supporting collection of this data.
We’ve been taking Internet IPv4 censuses regularly since 2006. In each census, we probe the entire allocated IPv4 address space. You may browse 8 years of data at our IPv4 address browser.
We recently put together an animation showing 8 years of IPv4 censuses, from 2006 through 2014.
These eight years show some interesting events, from an early “open” Internet in 2006, to full allocation of IPv4 by ICANN in 2011, to higher utilization in 2014.
All data shown here can be browsed at our website.
Data is available for research use from PREDICT or by request from us if PREDICT access is not possible.
This animation was first shown at the Dec. 2014 DHS Cyber Security Division R&D Showcase and Technical Workshop as part of the talk “Towards Understanding Internet Reliability” given by John Heidemann. This work was supported by DHS, most recently through the LACREND project.
We’re happy to welcome Greece to our browsable Internet map at http://www.isi.edu/ant/address/browse/ ! Of course Greece has always been in our Internet censuses, but George Xylomenos and George Polyzos of the Athens University of Economics and Business (their lab) helped set up a new observation site. Greece now provides a new vantage point for Internet censuses.
The differences in the census are small, as one would hope, since it’s a global Internet. However, when we look at latency (the time it takes for an IP address to reply to our requests), Greece gives us a European view.
Compare the lower-left corner of the Internet, since that is European IPv4 address space:
In addition to big thanks to George Xylomenos and George Polyzos of AUEB (σας ευχαριστώ!) and AUEB for institutional funding for this work. We also thank Christos Papadopoulos (Colorado State) for helping with many details, and Colin Perkins (U. Glasgow) for discussions about potential European hosts.
Data from our Greece census is available to researchers at no cost on the same terms as our existing census data. See our datasets page for details. Greek data starts with it61 as of 2014-08-29.
