Until then ISPs can only fix it with P2P aware caches, if the protocols did it then they wouldn't need the caches though P2P efficiency may go down It'll be interesting to see how Akamai & co. counter this trend. At the moment they can say it's better to use a local Akamai cluster than have P2P taking content from anywhere on the planet. Once it's mostly local traffic then it's pretty much equivalent to Akamai. It's still moving routing/TE up the stack though so will affect the ISPs network ops. > I have to admit that I have no idea how BT charges > ISPs for wholesale ADSL.

New GRH feature: Missing IPv6 prefixes => Many ISP's need IPv6 filter updates!
by Jeroen Massar 21 Jan '07

21 Jan '07

Hi, It seems that there are quite a few ISP's with IPv6 capabilities that are nicely filtering. Of course they also forget to actually update those filters. Blocks that are filtered by quite a number of ISP's that should not be filtered are: 2001:500::/30, 2001:678::/29, 2400::/16, 2600::/12, 2620::/23, 2a00::/16, and 2a01::/16 Note that some of these also have blocks upto /48's because of IPv6 PI space and micro allocations. Pay also special attention to 2001:678::/29 as that contains RIPE's Anycast TLD prefixes sized /48. It seems that these are nicely filtered out (then again RIPE stuck it in the middle of a block where only /32's come from normally) The recommended filters can be found here: http://www.space.net/~gert/RIPE/ipv6-filters.html Please check your filters, to be able to easily able to do what you are missing, you can use the following new GRH features: Want to know what ISP's are missing your prefix? See: http://www.sixxs.net/tools/grh/lg/ enter your prefix and look at the bottom. Want to know which ISP's filter what exactly? For ASN's peering with GRH, those can be looked up at: http://www.sixxs.net/tools/grh/dfp/ see under the heading for Missing prefixes, select and go. There are cross references between the tools so that you can look it easily from both references. Not peering with GRH yet? Check http://www.sixxs.net/tools/grh/peering/ and show the world that your IPv6 routing tables are okay. Which benefits you, but also other folks as they can check without having to find where to debug it ;) Of course, for comments, questions, suggestions, bug reports, don't hesitate to yell to info(a)sixxs.net! Enjoy the week ;) Greets, Jeroen

ISIS SNMP monitoring help
by Robert Boyle 20 Jan '07

20 Jan '07

Hello, I am posting here because I haven't been able to find what I need despite much searching and a previous unanswered post to cisco-nsp and I'm hoping someone here will have the answer. I need to find the SNMP OID for monitoring ISIS / CLNS neighbors: I tried walking: 1.3.6.1.3.37. and 1.3.6.1.3.37.1.5. and 1.3.6.1.3.37.1.5.1.1.2. and 1.3.6.1.3.37 which is the only OID I have found for ISIS seem to be invalid. I tried on a 7206 running 12.3(19) and a 6506 Sup720-3BXL running 12.2(18)SXF7 both of which are running ISIS and have many neighbors. I am looking for the ISIS roughly equivalent command to the BGP OID which we use to monitor BGP peers, but instead to monitor ISIS neighbor adjacencies: For BGP: 1.3.6.1.2.1.15.3.1.2.a.b.c.d For ISIS: ???? Thanks, Robert btw- For those who helped with my Foundry questions and those who wanted a summary, I am working on the summary now and we are also wrapping up our testing of the MLX/XMR boxes.

what happens when you put a typo in a DNSBL server?
by Wes Hardaker 20 Jan '07

20 Jan '07

A number of ISPs use njabl.org as a DNS BL server. However, starting jan 2 a new domain exists "njalb.org" which is serving A records for anything queried against it's DNS server. (note the difference: njaBL vs njaLB). Previous to this date a misconfigured ISP was just not being protected by the BL. Now, it's potentially dropping all mail from anyone because of the typo. # dig +short mail.merit.edu a 198.108.1.11 # dig +short 11.1.108.198.combined.njabl.org # dig +short 11.1.108.198.combined.njalb.org 64.20.43.107 66.45.232.66 66.45.232.75 66.45.237.187 I know of at least one ISP that is likely dropping mail from everyone... -- "In the bathtub of history the truth is harder to hold than the soap, and much more difficult to find." -- Terry Pratchett

Drone Armies C&C Report - 19 Jan 2007
by randy_vaughn＠Baylor.edu 19 Jan '07

19 Jan '07

This is a periodic public report from the ISOTF's affiliated group 'DA' (Drone Armies (botnets) research and mitigation mailing list / TISF DA) with the ISOTF affiliated ASreport project (TISF / RatOut). For this report it should be noted that we base our analysis on the data we have accumulated from various sources, which may be incomplete. Any responsible party that wishes to receive reports of botnet command and control servers on their network(s) regularly and directly, feel free to contact us. For purposes of this report we use the following terms open the host completed the TCP handshake closed No activity detected reset issued a RST This month's survey is of 5187 unique, domains (or IPs) with port suspect C&Cs. This list is extracted from the BBL which has a historical base of 14723 reported C&Cs. Of the suspect C&Cs surveyed, 678 reported as Open, 1769 reported as closed, and 812 issued resets to the survey instrument. Of the C&Cs listed by domain name in the our C&C database, 5845 are mitigated. Top 20 ASNes by Total suspect domains mapping to a host in the ASN. These numbers are determined by counting the number of domains which resolve to a host in the ASN. We do not remove duplicates and some of the ASNs reported have many domains mapping to a single IP. Note the Percent_resolved figure is calculated using only the Total and Open counts and does not represent a mitigation effectiveness metric.
