The BGP Visibility Scanner now for IPv6 prefixes
by Andra Lutu 09 Aug '13

09 Aug '13

Dear all, In November 2012 we have released the *BGP Visibility Scanner*, a tool that checks the visibility of IPv4 prefixes at the interdomain level. We are now happy to further make available the *visibility query for IPv6 prefixes*. Back in February 2013 we have presented the BGP Visibility Scanner at NANOG57. Please find the abstract and slides at the following link: http://www.nanog.org/meetings/abstract?id=2072 The tool is publicly available at *http://visibility.it.uc3m.es/* You can use it to retrieve prefixes injected by a certain origin AS that are not distributed everywhere (i.e., the Limited Visibility Prefixes). The tool has already been proven to be of real help to network operators. In particular, it helped identify and eliminate a large number of unintended IPv4 LVPs (e.g., prefixes leaked because of misconfigurations). We believe the tool is of interest for the ASes already deploying IPv6, enabling the operators to check the visibility status of their IPv6 prefixes and validate their routing policies. We would greatly appreciate your feedback on the limited visibility prefixes that you discover with the tool! For more information about the BGP Visibility Scanner project, we further refer you to the RIPE Labs article: https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner For any further questions, do not hesitate to contact us! Thank you, best regards, Andra

Strange entries from AS1 in global table
by Anurag Bhatia 08 Aug '13

08 Aug '13

Hello everyone I was looking at global IPv4 table and saw some strange entries from AS1. As per ARIN whois AS1 seems to be with Level3 but I noticed few prefixes of Brazil based ISP - Netvip http://bgp.he.net/AS1#_prefixes Looking at any prefix in detail, it seems like there are multiple ASNs announcing same prefix. E.g 177.185.96.0/24 - is being announced by AS1 as well as AS52931 (Netvip's allocated ASN). Same is true with 177.185.98.0/24, 177.185.98.0/24and so on. http://bgp.he.net/net/177.185.96.0/24 So seems like AS1 acting like a mirror for all announcements of AS52931. To see who exactly gave "transit" to AS1 by Netvip in Brazil, I checked Oregon and noticed these routes: 3356 3549 16735 52931 1 i Seems like AS52931 itself is acting as transit for AS1 (and AS16735 which seems like a backbone ISP in Brazil) is not filtering these routes further passing to Level3 (AS3549+AS3356). I am curious to know what could be possible reason for an ASN like AS1 acting in exact mirror of AS52931? Could it be a case of internal use of AS1 (assuming it to be private ASN)? May be it's a case of leaked internal routes? Appreciate your time & answer. Thanks. -- Anurag Bhatia anuragbhatia.com Linkedin <http://in.linkedin.com/in/anuragbhatia21> | Twitter<https://twitter.com/anurag_bhatia> Skype: anuragbhatia.com

questions regarding prefix hijacking
by Martin T 08 Aug '13

08 Aug '13

Hi, as probably many of you know, it's possible to create a "route" object to RIPE database for an address space which is allocated outside the RIPE region using the RIPE-NCC-RPSL-MNT maintainer object. For example an address space is from APNIC or ARIN region and AS is from RIPE region. For example a LIR in RIPE region creates a "route" object to RIPE database for 157.166.266.0/24(used by Turner Broadcasting System) prefix without having written permission from Turner Broadcasting System and as this LIR uses up-link providers who create prefix filters automatically according to RADb database entries, this ISP is soon able to announce this 157.166.266.0/24 prefix to Internet. This should disturb the availability of the real 157.166.266.0/24 network on Internet? Has there been such situations in history? Isn't there a method against such hijacking? Or have I misunderstood something and this isn't possible? regards, Martin

Seems like that might have been the first time I was annoying the Big Net Operators about why they route unroutable traffic.

Comcast contact
by Andy Ringsmuth 07 Aug '13

07 Aug '13

Any chance someone on this list is affiliated with Comcast who could contact me off-list? I have an employee in Virginia who works from home using, in part, a VOIP desk telephone tied into our office phone system back in Nebraska. She's had nothing but problems maintaining a stable connection and I'm at my wit's end to diagnose and fix whatever is causing her problems. I've got this exact setup with several employees around the country, but this one person is the only one who, 1 - has problems and 2 - has Comcast. Much appreciated! ---- Andy Ringsmuth andy(a)newslink.com News Link – Manager Technology & Facilities 2201 Winthrop Rd., Lincoln, NE 68502-4158 (402) 475-6397 (402) 304-0083 cellular

Andy, I posted in this list earlier in the week regarding Comcast and an issue my company was experiencing. I also posted at www.reddit.com/r/networking. I had numerous support staff from Comcast contact me over on Reddit. I would recommend posting there too.

RPKI and Trust Anchor question
by Marcel Plug 07 Aug '13

07 Aug '13

Hi Nanog, Does anyone have any inside information what may be happening in the effort to have a single trust anchor for RPKI? Is ICANN still working on this? If so is there any timeline or published info of any kind? Most of the information i can find is about 2 years old. Any links or info of any kind would be much appreciated. Thanks, Marcel Plug

This was just received a flood of bounces reporting delivery failuers on messages I sent to nanog@ a few days ago... Actually, I have just received a flood of about 15 messages just like this one around 9:00pm; from various nanog posts I had sent 2 to 5 days in the past...... Is that strange or what? I thought the mailing list software rewrote the return path to suppress bounces?

which firewall product?
by William Herrin 05 Aug '13

05 Aug '13

Hi folks, I'm trying to identify a firewall appliance for one of my customers. The wrinkle is: it has to be able to inspect packets inside an IPIP tunnel and accept/reject based on IP address, TCP port number and standard things like that. On the packet carried *inside* the IPIP tunnel packet. >From what I can tell, the Cisco ASA can't do this. Linux iptables can (with the u32 match module) but the customer wants an appliance, not a server. What appliances do you know of that can do this? Is there a different Cisco box? A Juniper firewall? Anything else? Thanks in advance, Bill Herrin -- William D. Herrin ................ herrin(a)dirtside.com bill(a)herrin.us 3005 Crane Dr. ......................
