BGP Javascript Map/Visualization
by Brian Johnson 26 May '22

26 May '22

Hey all, Sorry for the noise. Years ago someone here built and shared a javascript visualization of what their routers saw for the state of BGP and paths to get to various ASs. One could use WSAD and other keys to fly around and examine various other ASs. I thought it was as2814.net, but that seems to not be a thing anymore. Can someone refresh my memory where that might be? Or did it get taken down? Thanks in advance, - brian

FW: [arin-announce] ARIN Community Grant Program Application Deadline Extended
by John Sweeting 25 May '22

25 May '22

NANOGers - The ARIN Community Grant Program has extended the 2022 "call for applications” until 15 June. If you are aware of a non-commercial development or research project that could enhance Internet operations and might benefit from additional funding, please bring this opportunity to their attention. More information noted below. Thanks! John S. CCO, ARIN On 5/25/22, 12:52 PM, "ARIN-announce on behalf of ARIN" <arin-announce-bounces(a)arin.net on behalf of info(a)arin.net> wrote: If you have a project that needs funding, is non-commercial in nature, and benefits the Internet community within the ARIN service region, it’s not too late to apply to the 2022 ARIN Community Grant Program. The application deadline has been extended to 15 June 2022, so send your application in today: https://arin.smapply.net/prog/grants2022/ If you’re not familiar with ARIN’s Community Grant Program, learn more about it at: https://www.arin.net/grants or read our recent blog on the Top 5 Reasons to Apply for an ARIN Community Grant: https://www.arin.net/blog/2022/05/25/top-5-reasons-apply-grant-program/ ------------- About the ARIN Community Grant Program The ARIN Community Grant Program provides financial grants in support of operational and research projects that improve the overall Internet industry and Internet user environment that advance ARIN’s mission and broadly benefit the Internet community within the ARIN region. Projects must fit into one or more of these four broad categories: - Internet technical improvements that promote and facilitate the expansion, development, and growth of the infrastructure of the Internet consistent with the public interest - Registry processes and technology improvements that help maintain a globally consistent and highly usable Internet Number Registry system - Informational outreach that advances the Internet on topics such as, but not limited to: IPv6 deployment, Internet research, and Internet governance - Research related to ARIN’s mission and operations For 2022, the ARIN Board of Trustees has approved a total expenditure of up to $60,000 (USD) for grants of varying amounts, starting at $1,000 to $20,000 (USD) and based on project need. We encourage all applicants to clearly demonstrate how projects meet eligibility guidelines and selection criteria through the application form to improve chances of selection. ARIN looks forward to funding important projects through the ARIN Community Grant Program in 2022.

RE: Newbie x Cisco IOS-XR x ROV: BCP to not harassing peer(s)
by Jakob Heitz (jheitz) 24 May '22

This attack will work very well until the victim starts advertising its prefix. The victim may not notice the fake advertisement because the fake advertisement will not reach the victim AS due to AS-path loop checking. So potential victims must advertise all prefixes that they register in RPKI or subscribe to an Internet monitoring service to detect the fake advertisements. And don't forget maxlen. You must advertise in BGP every prefix covered by maxlen.

Question re prevention of enumeration with DNSSEC (NSEC3, etc.)
by Amir Herzberg 24 May '22

24 May '22

Hi NANOGers, I have a small question re DNSSEC `proof of non-existence' records: NSEC, NSEC3 and the (dead?) NSEC5 proposal. <begin background (probably known to all/most):> NSEC3 was motivated as a method to prevent Zone enumeration, then Berenstein showed its defense is pretty weak. RFC7129 (White Lies) prevents this enumeration attack but requires online signing with the zone's key, which introduces another vulnerability and, of course, overhead of online-signing. NSEC5 was proposed to prevent enumeration without online signing, so arguably more secure than RFC7129, but has comparable online overhead and appears `dead'; the I-D expired (last update July'17). Note that NSEC3 also supports `opt-out', which reduces overhead for adoptions in domains with many non-adopting ASes, and I believe is not supported by NSEC. <end background> Questions: - Do you find zone enumeration a real concern? - Do you think the white-lies countermeasure is sufficient and fine, or do you have security and/or performance concern (or just think it's pointless)? - and the final question... would you think an alternative to NSEC5 which will be more efficient and simpler would be of potential practical importance, or just a nice academic `exercise'? I'm really unsure about these questions - esp. the last one - and your feedback may help me decide on the importance of this line of research. Just fun or of possible practical importance? thanks and peace, Amir -- Amir Herzberg Comcast professor of Security Innovations, Computer Science and Engineering, University of Connecticut Homepage: https://sites.google.com/site/amirherzberg/home `Applied Introduction to Cryptography' textbook and lectures: https://sites.google.com/site/amirherzberg/applied-crypto-textbook <https://sites.google.com/site/amirherzberg/applied-crypto-textbook>

To address the risk of somebody exhausting your memory by dumping a ton of routes on you, we added two new options to "soft-reconfiguration inbound" in IOS-XR. RPKI-dropped-only Saves a copy of only the routes dropped by an RPKI validation-state test in neighbor-in route-policy. RPKI-tested-only Saves a copy of only the routes tested in an RPKI validation-state test in neighbor-in route-policy. This was released in 7.3.1 in Feb 2021. The bug CSCwb17937 was fixed in 7.5.2, just released. Fixed a few other things in 7.5.2 also. Tomoya, apologies that you had a terrible time with it.
