Spoofer Report for NANOG for Apr 2021
by CAIDA Spoofer Project 08 May '21

08 May '21

In response to feedback from operational security communities, CAIDA's source address validation measurement project (https://spoofer.caida.org) is automatically generating monthly reports of ASes originating prefixes in BGP for systems from which we received packets with a spoofed source address. We are publishing these reports to network and security operations lists in order to ensure this information reaches operational contacts in these ASes. This report summarises tests conducted within usa, can. Inferred improvements during Apr 2021: ASN Name Fixed-By 53356 FREE RANGE CLOUD 2021-04-15 20150 ANYNODE 2021-04-28 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Apr 2021: ASN Name First-Spoofed Last-Spoofed 209 CENTURYLINK-US-LEGACY-QWEST 2016-08-16 2021-04-20 40676 AS40676 2016-08-29 2021-04-04 6128 CABLE-NET-1 2016-09-03 2021-04-13 20412 CLARITY-TELECOM 2016-09-30 2021-04-30 6181 FUSE-NET 2016-10-10 2021-04-29 11427 TWC-11427-TEXAS 2016-10-21 2021-04-30 30036 MEDIACOM-ENTERPRISE-BUSINESS 2016-11-16 2021-04-13 22898 ATLINK 2016-12-16 2021-04-30 63296 AWBROADBAND 2017-09-01 2021-04-28 546 PARSONS-PGS-1 2017-11-20 2021-04-12 12222 AKAMAI 2018-02-14 2021-04-23 393564 SPOKANE 2018-06-05 2021-04-06 33452 RW 2018-09-19 2021-04-30 20448 VPNTRANET-LLC 2018-09-20 2021-04-29 5078 ONENET-AS-1 2020-04-06 2021-04-21 6391 URBAN-15 2020-05-29 2021-04-28 208188 PUGET-SOUND-NETWORKS 2020-12-04 2021-04-24 Further information for these tests where we received spoofed packets is available at: https://spoofer.caida.org/recent_tests.php?country_include=usa,can&no_block… Please send any feedback or suggestions to spoofer-info(a)caida.org

Re: Perhaps it's time to think about enhancements to the NANOG list...?

May I suggest that if you *really* want such enhancement, perhaps upgrade the mailing-list to mailman3. It's still mailman but with those 'modern' features. But more importantly (not only for NANOG by the way), maybe some kind of 'mailing-list 101' can be helpful sometimes. Many $vendors are fighting hard to make people forget what an email is. -- Willy Manga @ongolaboy https://ongola.blogspot.com/

IS-IS and IPv6 LLA next-hop - just Arista, or everyone?
by Adam Thompson 06 May '21

06 May '21

Hey, just checking as I don’t have any Cisco or Extreme or Juniper gear running IS-IS to verify myself… On current Arista (7280SR2K) and older Brocade (MLXe) routers, the IPv6 next-hop address in IS-IS seems to always be the link-local address of the neighbour, instead of any manually-assigned address on the interface. I believe this is *not* the case with Cisco, in particular. Not sure about other vendors, I don’t have any handy that can run IS-IS. I don’t appear to have any knobs to control this behaviour, and haven’t found anything related in the docs. Can anyone confirm that Cisco or other vendors does/do not do this (prefer LLA over GUA)?

Re: Google IP Geolocation
by Hank Nussbacher 03 May '21

03 May '21

The issues that others had earlier this month just hit us this morning. Users in Israel (132.74.0.0/15) trying to access Google.com or Youtube.com appear as coming from Iceland (see screenshot). Change happened overnight. Someone internally in Google's geo-location group typo'ed Israel as Iceland. We have GGC access and Google ISP Portal access but why should we have to change the geolocation which worked well since forever just because someone internally messed up? Regards, Hank

link monitoring
by Baldur Norddahl 01 May '21

01 May '21

Hello We had a 100G link that started to misbehave and caused the customers to notice bad packet loss. The optical values are just fine but we had packet loss and latency. Interface shows FEC errors on one end and carrier transitions on the other end. But otherwise the link would stay up and our monitor system completely failed to warn about the failure. Had to find the bad link by traceroute (mtr) and observe where packet loss started. The link was between a Juniper MX204 and Juniper ACX5448. Link length 2 meters using 2 km single mode SFP modules. What is the best practice to monitor links to avoid this scenarium? What options do we have to do link monitoring? I am investigating BFD but I am unsure if that would have helped the situation. Thanks, Baldur
