You should also create a bogons list for your BGP routes which you accept from your upstream. Block all RFC1918 space and unassigned public addresses too. Just keep on top of it when new allocations are put into use. We see all kinds of crazy things which people try to announce (and successfully too - up to our borders anyway.) -Robert Tellurian Networks - Global Hosting Solutions Since 1995 http://www.tellurian.com | 888-TELLURIAN | 973-300-9211 "Well done is better than well said." - Benjamin Franklin

RE: Verizon PSTN continued
by Wallace Keith 10 Nov '06

10 Nov '06

Working with 2 other carriers on a similar issue, response I rec'd was congestion due to automated political dialers. Not sure if I believe that or not... -Keith -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of David Hubbard Sent: Tuesday, November 07, 2006 12:32 PM To: nanog(a)merit.edu Subject: Verizon PSTN continued The thread yesterday didn't seem to get into much detail; I'm wondering if anyone knows more about what is going on with Verizon? Our PSTN service with XO seems to be affected again by what XO claims is a Verizon problem but they wouldn't elaborate on why they feel that to be the case; I was just amazed to even get someone on the phone at XO since normally they are unreachable. I am inclined to partially believe them since I've found other numbers that I know to be with other carriers that are not working. XO claimed this was at least a regional issue of Verizon's that is affecting multiple carriers. David

Hello; There has been discussion on the list before about the problems caused by placing IP networks on large mobile platforms (i.e., mobile platform internetworking, or MPI). Terry Davis and Will Ivancic are presenting on this to the NEMO WG at the IETF right now; we have created a mailing list and a web site devoted to this. Mailing list information and presentations and documents can be found at http://www.multicasttech.com/mpi/ If you interested, you are welcome to join and contribute. Regards Marshall Eubanks

Yahoo! Mail Servers
by Dave Mitchell 09 Nov '06

09 Nov '06

Hey all, Sorry for the delay. Thanks to Peter Moody for letting me know some of you were looking for Yahoo!. The issue some of you are seeing is that your mailserver IPs are being grey-listed after a certain number of emails and being traffic shaped. To have your legitimate mailservers added to a white list, please refer to the following info. http://help.yahoo.com/help/us/mail/defer/defer-06.html Thanks! -dave p.s. Chuck, must be 'game on' in hell twice since Petach and I both work for Yahoo. :) "suspect I'll be refereeing a Flyers** vs Chiefs*** Ice Hockey game in hell before that happens. However, if an actual human being affiliated with Yahoo does get back to you prior to the Zamboni being delivered to the netherworld, please pass them over my way when your done with them. --chuck" -- ----------------------------------- Dave Mitchell Yahoo!

RE: SprintLink peering issue in Chicago?
by Soren Telfer 09 Nov '06

09 Nov '06

Via our sprintlink , connectivity to Level3 in Chicago was down for about an hour, we got confirmation from sprint at 4:00 that it was a major router issue, and they were investigating the root cause. Transit to Level3 seems to be working not at 4:00 PM

To answer a slightly different question, I was actually thinking about the issues of address space hijacking. So this is where address space that has been legitimately allocated and is properly maintained in routing registries is announced unauthorized by a third party. Theres nothing weird about the BGP announcement or the address space, except your Yahoo traffic seems to traceroute to North Korea rather than California..... Less nasty things would be caused by fat fingers, typos in prefixes, accidental announcment of supernets or subnets.... What I'm getting at here is that if someone announces 1.0.0.0/16 then when I spot it I'll raise an issue and alert whoever screwed up but does it break anything? Not normally. But if I accidentally redistribute my static routes to google.com into BGP my phone's going to get busy PDQ! Steve
