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/ -- "Fergie", a.k.a.

bgp question
by adrian kok 25 May '06

25 May '06

Hi all Thank you all for your answer to my previous question 'RFC1918 from ISP' I have another BGP question, and may be related to BGP dampening. We have a client whose IP is in the block X.X.0.0/19 which doesn't show in our router. However, our BGP log records that we have received this route from our peer isp. I reboot the router, seeing that the route was in our router only to disappear again after couple of minutes. I suspect that it may have been removed by the BGP dampening feature in our router. By disabling the feature, the route will stay in our router. Q1/ My only understanding of the benefit of this feature is to prevent 'unstable' route from flooding to our router, causing a CPU overflow. What's the risk of leaving this off? Q2/ What is the cause of these route that frequently send to our router as stated below? Once our other routes are in our BGP DB, then it will not be re-broadcast to us except withdraw from our peer isp > 2006/05/26 08:30:34 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:33:42 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:36:46 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:39:49 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:45:25 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:48:00 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:49:02 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:51:34 BGP: our-peer-isp rcvd x.x.0.0/19 > 2006/05/26 08:52:36 BGP: our-peer-isp rcvd x.x.0.0/19 Q3/ Do you know any good website to montior the routing network? I just heard this scoreboard.keynote.com from http://isc.sans.org/diary.php but it needs register Thank you very much

"Can be" is not sufficient (in and of itself, that is) reason to block. _Anything_ "can be" used as part of a DOS attack. TTL-E messages _do_ have legitimate function in network management. TTL-E messages _can_ originate from RFC1918 space, addressed to 'public internet' addresses. Usefully, and meaningfully. Ever hear of 'traceroute'? Ever use it where packets went across a network using RFC1918 internally? Ever had a route die _between_ two RFC1918 addressed nodes on somebody elses network? If you don't like that example, substitute "host/network unreachable", or 'ICMP redirect'. Or packet-size limit exceeded for a 'DNF' packet.

You need to learn to read. I said "malicious content", not 'used in a malicious fashion'. Packets that could have legitimate meaning should be passed on. Packets that _cannot_ have legitimate meaning should not be. > >It's even more comical when the NSP uses RFC1918 space internally, and does > >*not* filter those source addresses from their customers. > > You mean like Comcast using Cisco routers in their head-ends and > having the 10/8 address show up in traceroutes and so forth? not at all. You're either ignorant of network architecture, or trying to pick fights. I was talking about a situation where a customer machine of a network that uses RFC1918 addresses internally starts sending malicious packets with a RFC1918 source address that _matches_ that of one of the *in*use* addresses on the service-provider network. AND the service-provider does not do ingress (from the customer) or egress (to the customer) filtering of RFC1918 address-space. Customer A's machine starts attacking Customer B, C, D, E, F ...; those ill-informed customers don't null-route outbound RFC1918 addresses; you get an 'inadvertent' smurf attack on the NSP resource. It's comical, because the ISP's 'bad practice' facilitated the attack on the ISP. "Traceroute", by the way, *is* one of those 'legitimate' cases for which RFC1918 source-address packets should be allowed across network boundaries. Proper "good net neighbor" egress filtering of RFC1918 source addresses takes a number of separate rules. Several 'allows', followed by a default 'deny'. > Not sure > to what degree it's the NSP's fault vs. the router vendors', but yes.

If everybody did _egress_ filtering of 'cannot possibly be legitimate' traffic, ingress filtering of that traffic would not be necessary. Unfortunately, not everybody does, so ingress filtering _is_ necessary. 'ingress' filtering is self-defense. 'egress' filtering is about 'being a good net neighbor'. > >Some of us, on the other hand, _do_ object. > > And some of us pay for bandwidth, care about getting congestion > problems from useless traffic, etc. Perhaps it makes the case a lot > clearer for selling "better than equal" service to the highest bidder > if your network is overrun with undesired traffic. > >
