I'm having a particularly bad time with dispatch/install for ATT broadband in the GA region. Does anyone have any email-phone numbers of an exec/helpful person for that region? Steven White? Thanks andrew

Re: NY ranks #1 in Internet b/w

>But if you look at trunks going into *another* country the same report comes >to this ranking. > > London > Paris > New York > Amsterdam > Frankfurt > >This report also says that the relevance of US for Internet is decreasing. Well, yeah. Interregional Internet bandwidth: connects between world regions. Based on aggregate sum, New York is most significant metro. International Internet bandwidth: connects between countries. Based on aggregate sum, London is most significant metro. (Hint: Europe has all those border-crossing fiber rings.) Relevance of US for [global] Internet: decreasing. Region-to-region traffic still goes mostly through US, but in most regions, historical trend is for country-to-country traffic to stay in-region more often, eg more intraregional links in Asia (7 percent of its aggregate international Internet bandwidth at mid-1999, 13 percent at 2000, 18 percent at 2001). Not particularly earthshattering news, but perhaps interesting. Definitions: http://www.telegeography.com/products/books/pg/faq.html >As ever: never trust a statistic unless you faked it yourself ... Yup. But if people put enough time and (properly-directioned) effort into their fakes, they can end up with something distinctly usable for a limited set of applications. Statistics are a trade-off. cheers Bram --

214/8 and 215/8
by smd＠clock.org 01 Nov '01

01 Nov '01

Hi - 214/8 and 215/8 seem to have been allocated to the U.S. DoD in ca. 1998. There does seem to be a few sizeable announcements (which overlap a few not-so-sizable ones), but I have to wonder if anyone can explain the grounds on which they were allocated these two /8s, and which body did the allocation. Anyone? Sean.

Nimba Question.
by Gyorfy, Shawn 01 Nov '01

01 Nov '01

Hey what's going on? Question for you all. We are a BLEC, we give each building a T1 and router and back haul the circuit to our NOC were we distribute the packets to our service providers. The problem I see, some of our clients in the building, there computers are infected with the NIMBA virus / Code Red. I get emailed from firewall administrators about the possible port scan, and then I disconnect the customer until he updates his servers and cleans them. I was wondering if I can do anything on my end to prevent the Nimba going out on my end. I have been reading about Cisco's NBAR feature with class maps but I don't want to put that on the core because it will kill the box (Cisco 10K ESR, (2) 7507, (2) 7206). Plus cisco stated that it can only hand 24 concurrent web hits. So that's out. I was also thinking about putting that on the building routers but 75% aren't Cisco, they are Lucent Access Points. Any suggestions would be appreciated. shawn.

/8 mysteries
by David Barak 01 Nov '01

01 Nov '01

Personally, I find the bogus /8s which are actually IN the routing table to be about as interesting as those which are not - According to route-views.oregon-ix.net, only 22 /8s are routed in the whole, and several of them are bogus - B 64.0.0.0/8 [20/0] via 195.211.29.22, 00:17:00 B 80.0.0.0/8 [20/21040] via 4.0.0.2, 00:53:17 B 66.0.0.0/8 [20/24403] via 198.32.162.18, 09:19:59 B 62.0.0.0/8 [20/21040] via 4.0.0.2, 09:15:21 B 39.0.0.0/8 [20/24403] via 198.32.162.18, 09:19:59 -David Barak "Quis custodes ipsos custodiet?" - Juvenal __________________________________________________ Do You Yahoo!?

| The full RFC2050 justification for a /7's worth of space would | be a mighty and wondrous thing to behold. Indeed, and since 2050 predates the allocation date listed at http://www.iana.org/assignments/ipv4-address-space by a year and a half, I hope such a full justification exists for what otherwise would be a rather creepy land-grab. Maybe someone who does FOIAs regularly could start on one, since nobody seems to have jumped up to justify the two /8s? Sean. (studiously avoiding the issue of the IANA institutionalization process underway now, which presumably will have a practical bearing on such matters...)
