Spoofer Report for NANOG for Aug 2022
by CAIDA Spoofer Project 08 Sep '22

08 Sep '22

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 Aug 2022: ASN Name Fixed-By 54825 PACKET 2022-08-15 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Aug 2022: ASN Name First-Spoofed Last-Spoofed 40285 NORTHLAND-CABLE 2016-07-17 2022-08-06 209 CENTURYLINK-US-LEGACY-QWEST 2016-08-16 2022-08-27 6128 CABLE-NET-1 2016-09-03 2022-08-02 27364 ACS-INTERNET 2016-09-27 2022-08-09 20412 CLARITY-TELECOM 2016-09-30 2022-08-31 271 BCNET 2016-10-24 2022-08-11 22898 ATLINK 2016-12-16 2022-08-22 1246 TLL-WEST 2017-04-20 2022-08-08 701 UUNET 2017-06-14 2022-08-25 26253 SCINTERNET 2017-06-30 2022-08-10 63296 AWBROADBAND 2017-09-01 2022-08-10 31863 DACEN-2 2018-04-26 2022-08-07 33452 RW 2018-09-19 2022-08-29 21804 ACCESS-SK 2019-06-09 2022-08-31 398836 NP-NETWORKS 2021-03-12 2022-08-27 22773 ASN-CXA-ALL-CCI-22773-RDC 2021-10-24 2022-08-28 394414 E2WS 2022-05-08 2022-08-06 397086 LAYER-HOST-HOUSTON 2022-06-16 2022-08-27 399486 2022-06-18 2022-08-25 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

NANOG 86 - Hotel Group Rate
by Adam Korab 08 Sep '22

08 Sep '22

The group rate of $250 USD/night is full and no longer available. Online availability is $355 USD/night. But if you call, wait on hold, and ask for the AAA discount, the rate is $305 USD/night. Thought I would share as it may help others save a little money. AK

AS15960 abuse contact?
by Tim Burke 07 Sep '22

07 Sep '22

Anyone have an abuse contact at AS15960 / bluehornet / mapp.com that doesn't go to /dev/null? I have been getting a ridiculous amount of political spam from them, and despite repeatedly unsubscribing and submitting abuse complaints, the garbage increases exponentially. V/r Tim

Contacts for AT&T Postmaster, AWS WAF, Azure WAF
by Malli, Vishal 07 Sep '22

07 Sep '22

Hi All, We recently obtained our first /24 from the ARIN waiting list. We've been testing it out the past few weeks, and we're finding that it's blocked in a couple places. Geolocation data has already been updated with the major providers, and the range is not listed in any known blocklists. I'm looking for contacts for the following. Please reach out off-list if you can assist. Thank you in advance! * AT&T Postmaster - getting 521 errors, already emailed 'abuse_rbl(a)abuse-att.net' multiple times but no response. * AWS WAF - some sites that use awselb/2.0 are throwing a "403 Forbidden." They work fine from an older IP. Product vendors are unable to resolve so far. * Azure WAF - one site is completely resetting our connection attempts. Works fine from an older IP. Product vendor is unable to resolve so far. Vishal Malli IT Systems Engineer City of Manteca, CA vmalli(a)manteca.gov<mailto:vmalli@manteca.gov>

RFC: BOGONs over BGP, adding some ranges
by James Shank 06 Sep '22

06 Sep '22

Dear NANOG! As many of you know, Team Cymru runs a free service delivering updated BOGONS to networks around the world. We've been doing this for decades at this point. For more information about this service, please see https://www.team-cymru.com/bogon. Recently, we've discussed internally a discrepancy between our BGP based feed and the other formats we deliver for our Traditional BOGONS feed. For historic reasons, we previously omitted delivery of some ranges that are BOGONS from our BGP advertisements. We are considering adding the below ranges back in, but want to hear feedback from the community on these ranges prior to advertising them, out of an abundance of caution. The below ranges are what we are currently considering advertising: 0/8 (this one we already have concluded is safe as it is already advertised in our "FULL BOGONS" set.) 127/8 224/4 240/4 Note that 224/4 and 240/4 may be aggregated differently in our advertisement, but are broken out here to facilitate discussion. So, fellow NANOGers, what say ye? I would love to hear your feedback, pro or con, well-reasoned with data points or general "argh! there be dragons!" sentiments. Looking forward to seeing folks in Hollywood for N86! Cheers! James -- *James Shank* Chief Architect of Community Services and Sr. Security Evangelist e: jshank(a)cymru.com o: +1 847 378-3365
