by CAIDA Spoofer Project 08 Jan '22

08 Jan '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 Dec 2021: ASN Name Fixed-By 54825 PACKET 2021-12-03 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Dec 2021: ASN Name First-Spoofed Last-Spoofed 577 BACOM 2016-03-09 2021-12-29 209 CENTURYLINK-US-LEGACY-QWEST 2016-08-16 2021-12-30 20412 CLARITY-TELECOM 2016-09-30 2021-12-31 6181 FUSE-NET 2016-10-10 2021-12-27 11427 TWC-11427-TEXAS 2016-10-21 2021-12-24 32440 LONI 2016-11-03 2021-12-30 12083 WOW-INTERNET 2016-11-09 2021-12-22 1403 EBOX 2016-11-12 2021-12-08 22898 ATLINK 2016-12-16 2021-12-28 54119 BOINGO-MDU 2017-04-14 2021-12-30 701 UUNET 2017-06-14 2021-12-04 63296 AWBROADBAND 2017-09-01 2021-12-28 546 PARSONS-PGS-1 2017-11-20 2021-12-23 12222 AKAMAI 2018-02-14 2021-12-30 33452 RW 2018-09-19 2021-12-31 62904 EONIX-COMMUNICATIONS-ASBLOCK-6 2019-07-14 2021-12-29 398836 NP-NETWORKS 2021-03-12 2021-12-31 56207 Converge 2021-03-26 2021-12-01 399318 2021-08-29 2021-12-27 63457 EMPIRE-CONNECT 2021-09-08 2021-12-30 212934 AS_POTVIN 2021-10-03 2021-12-27 22773 ASN-CXA-ALL-CCI-22773-RDC 2021-10-24 2021-12-29 46449 ASTREA-NORTHWI-WESTUPMI 2021-11-07 2021-12-30 394437 PSLIGHTWAVE 2021-12-02 2021-12-27 62887 WHITESKY-COMMUNICATIONS 2021-12-03 2021-12-29 54201 WEWORK-MANAGEMENT-LLC 2021-12-16 2021-12-16 139247 2021-12-22 2021-12-22 46997 NATOLAB 2021-12-22 2021-12-29 5009 EATEL 2021-12-26 2021-12-26 4922 SHENTEL 2021-12-28 2021-12-28 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

REMINDER - ARIN-NONAUTH IRR to be deprecated at the end of March (Retirement of ARIN Non-Authenticated IRR on 31 March 2022)
by John Curran 03 Jan '22

03 Jan '22

Folks - Just a reminder of an important change taking place later this year. Happy New Year, /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Subject: [arin-announce] Reminder: Retirement of ARIN Non-Authenticated IRR on 31 March 2022 Date: 3 January 2022 at 10:02:04 AM EST To: "arin-announce(a)arin.net<mailto:arin-announce@arin.net>" <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> This announcement is to remind you of the previously-announced retirement of the ARIN non-authenticated Internet Routing Registry (IRR) on 31 March 2022. The following information is repeated from the initial announcement: ARIN has been engaged in a multi-year project to create and deploy a new and improved Internet Routing Registry (IRR). As a result of these efforts, ARIN now provides users with the ability to create, update, and delete objects in ARIN’s authenticated IRR database using ARIN Online or ARIN’s RESTful API. Unfortunately, use of ARIN’s previous non-authenticated email-based IRR service actually increased after ARIN released its authenticated IRR, in opposition to the outcome ARIN anticipated when improving its IRR. On 8 February 2021, ARIN held a consultation to solicit input on the retirement of ARIN’s non-authenticated email-based IRR service. This retirement was originally scheduled for 30 September 2021. Based on community input, the proposed date for the ARIN-NONAUTH retirement was delayed to 31 March 2022 to allow more transition time for users. We also notified by email Points of Contact (POCs) of organizations who have objects in the ARIN-NONAUTH database of the retirement date and offered them our assistance with the transition. This announcement serves as a reminder that ARIN will retire its ARIN-NONAUTH IRR database on 31 March 2022. After this date, users will no longer be able to create, update, or delete records in the ARIN-NONAUTH database, and the ARIN-NONAUTH data stream will no longer be available in Near Real Time Mirroring (NRTM) or via FTP or Whois Port 43. If you have questions about this transition or need assistance, you can contact us by: - submitting an Ask ARIN ticket or chat with us using your ARIN Online account - emailing the Routing Security Team at routing.security(a)arin.net<mailto:routing.security@arin.net> - contacting the Registration Services Help Desk by phone Monday through Friday, 7:00 AM to 7:00 PM ET at +1.703.227.0660 Regards, Brad Gorman Senior Product Owner, Routing Security American Registry for Internet Numbers (ARIN)

Carrier Options in Hong Kong
by nanoguser99 28 Dec '21

28 Dec '21

Nanog, Currently my organization uses PCCW which we pay through the nose for and I'm looking to cut them. This was put in place before me. I was informed that PCCW is "the carrier" in Hong Kong but based on my analysis I'm not sure that's the case. My analysis of carriers such as Lumen and Cogent put them on par with PCCW. Pings to random IPs in HK are reasonable fast on all of them, same with pings to cloud providers. Access to mainland is not a hard requirement but just to check they all had 300+ ms latency to known IPs in Shanghai and Tanjin. I know some regions such as Korea or Dubai are monopolized where the wrong carrier takes you on a far away path to get a few blocks down the street. I don't need anything special, just general DIA and good access to eyeballs and internet. I just wanted to see people's opinions here as APAC connectivity can be tricky. - Nanoguser99 Sent with [ProtonMail](https://protonmail.com/) Secure Email.
