Internet address space: new technical paper and browsable map

A number of folks expressed interest in our ANT census of the Internet address space at <>.

We have three recent updates, a new TECHNICAL REPORT and a BROWSABLE INTERNET ADDRESS MAP, and a PROJECT BLOG.

We have have released a new TECHNICAL REPORT describing the methodology,  ISI-TR-2008-649 at <>.
This report should completely supersede our previous report (#640), adding:

  • evaluation in ping accuracy, both absolutely and relative to TCP probing
  • estimation of error in our evaluations of hosts and server counts
  • validation of our approach to firewall detection
  • significant improvements in organization and presentation

We have also put up a BROWSABLE INTERNET ADDRESS MAP at <>.

With the Google maps engine, this map lets you zoom from an overview to any part of the address space, including showing individual hosts (permuted for anonymization).

Finally, we now have a PROJECT BLOG to allow folks to track future developments: <>.  We plan to do all future announcements via the blog rather than with general e-mail messages, so folks can opt-in to what they want to hear.

We welcome any comments about the map or technical report, either to our group mailing list (ant, then at, or to individuals.

Hello world!

Welcome to the ANT Project Blog.  Folks are welcome to subscribe to the RSS feed for this blog if they wish to track research related to the analysis of Internet traffic in the ANT group at ISI, USC, and CSU.  We expect this blog to be very low traffic (research takes time!).
