Some people need whatever bandwidth they can get for ranting. Of course routing reports, virus reports and botnet bgp statistics take away a lot of valuable bandwidth that could otherwise be used for nagging. On the other hand without Gadi's howling for the wolves those wolves might be lost species and without the wolves all the nagging and ranting would make less fun.
lets see, should we be concerned? here are a few interesting tables, the cnt column is new IP addresses we have seen in the last 5 days. The first table is Tier-2 ASNs as classified by Fontas's ASN Taxonomy paper [1] The second table is Universities. The ASN concerned are just in the announced by orgs in USA as to imply that they should be on NANOG. Let me say it again the counts are NEW observations in the last 5 days. also note I'm not Gati, and I've got much more data on everyones networks. -rick New compromised unique IP addresses (last 5 days) Tier-2 ASN +-------+------------------------------------+-------+ | asnum | asname | cnt | +-------+------------------------------------+-------+ | 19262 | Verizon Internet Services | 35790 | | 20115 | Charter Communications | 4453 | | 8584 | Barak AS | 3930 | | 5668 | CenturyTel Internet Holdings, Inc. | 2633 | | 12271 | Road Runner | 2485 | | 22291 | Charter Communications | 2039 | | 8113 | VRIS Verizon Internet Services | 1664 | | 6197 | BellSouth Network Solutions, Inc | 1634 | | 6198 | BellSouth Network Solutions, Inc | 1531 | | 9325 | XTRA-AS Telecom XTRA, Auckland | 1415 | | 11351 | Road Runner | 1415 | | 6140 | ImpSat | 1051 | | 7021 | Verizon Internet Services | 961 | | 6350 | Verizon Internet Services | 945 | | 19444 | CHARTER COMMUNICATIONS | 845 | +-------+------------------------------------+-------+ Universities, new unique ip last 5 days +-------+--------------------------------+-----+ | asnum | left(asname,30) | cnt | +-------+--------------------------------+-----+ | 14 | Columbia University | 93 | | 3 | MIT-2 Massachusetts Institute | 45 | | 73 | University of Washington | 25 | | 7925 | West Virginia Network for Educ | 24 | | 4385 | RIT-3 Rochester Institute of T | 20 | | 23369 | SCOE-5 Sonoma County Office of | 19 | | 5078 | Oklahoma Network for Education | 18 | | 3388 | UNM University of New Mexico | 18 | | 55 | University of Pennsylvania | 13 | | 159 | The Ohio State University | 12 | | 104 | University of Colorado at Boul | 12 | | 4265 | CERFN California Education and | 11 | | 693 | University of Notre Dame | 10 | | 2900 | Arizona Tri University Network | 9 | | 2637 | Georgia Institute of Technolog | 9 | +-------+--------------------------------+-----+ [1] http://www.ece.gatech.edu/research/labs/MANIACS/as_taxonomy/
