Hi,

Network 1.0.0.0/8 has been assigned by IANA to APNIC on the 19th January 2010, for use for as public unicast space for further address allocations and assignments. Before APNIC commences allocations and assignments from this space, APNIC has undertaken a study into 1.0.0.0/8. The particular question under investigation here is the extent to which addresses in network 1.0.0.0/8 are an "attractor" for unwanted traffic. In particular, is there a significant level of "leakage" of supposedly private use traffic directed to addresses in 1.0.0.0/8 that leak into the public Internet?

The report on this study is now available at http://www.potaroo.net/studies/1slash8/1slash8.html, and two recommendations are included in this report regarding reservations of particular address blocks and further followup studies.

We would be interested in any comments on this report and its recommendations. Please followup to apnic-talk@lists.apnic.net, or directly to us at research@apnic.net if you prefer.

thanks,

Geoff Huston Chief Scientist, APNIC
