Spoofer Report for NANOG for Dec 2025
by CAIDA Spoofer Project 08 Jan '26

08 Jan '26

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 2025: ASN Name Fixed-By 4901 CAAREN 2025-12-04 393397 LREC-LRT 2025-12-05 Further information for the inferred remediation is available at: https://spoofer.caida.org/remedy.php Source Address Validation issues inferred during Dec 2025: ASN Name First-Spoofed Last-Spoofed 7029 WINDSTREAM 2016-06-21 2025-12-06 32329 MONKEYBRAINS 2018-11-28 2025-12-04 22883 CONDENAST 2019-05-29 2025-12-10 21804 ACCESS-SK 2019-06-09 2025-12-28 36352 AS-COLOCROSSING 2020-10-08 2025-12-25 55016 IMPER-AS-1 2021-05-18 2025-12-27 22773 ASN-CXA-ALL-CCI-22773-RDC 2021-10-24 2025-12-18 12183 TALKIE-COMMUNICATIONS 2022-12-10 2025-12-26 400282 2023-04-27 2025-12-26 393577 SCCNET 2023-05-03 2025-12-25 394684 AS-GOLD 2024-01-17 2025-12-27 27425 ASN-IDK-27425 2024-02-21 2025-12-22 53755 IOFLOOD 2024-02-23 2025-12-26 393530 TLU 2024-05-22 2025-12-30 19935 CRRS 2024-05-29 2025-12-16 273143 2025-01-22 2025-12-27 54334 ROYA 2025-03-13 2025-12-29 273843 2025-04-02 2025-12-25 204969 AS_CIRTEL 2025-10-22 2025-12-07 22890 NCC-OMAHA 2025-12-06 2025-12-06 399728 PFOUNDATION 2025-12-10 2025-12-10 32425 SKB3-ARIN-BGP 2025-12-12 2025-12-12 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

u.arin.net - slow to update ?
by vom513 07 Jan '26

07 Jan '26

I don’t mean this as a complaint. Looks like this NS is ran out of PCH. I made some changes to a zone via ARIN (within ip6.arpa) and it seems like all auth servers listed one level up picked it up within an hour (possibly quicker) - however u.arin.net is still in the dark. Is this a known issue ? I can wait 24 hours - not a biggie… Thanks.

SuperBox IPTV STBs
by Corey Smith 06 Jan '26

06 Jan '26

I am curious if other Operators are seeing issues on their networks due to users with Android STBs called SuperBox? It appears there are some recent findings about a malware called KIMWOLF. We are seeing several customers report issues due to their IP being added to a block list. Our Trouble department may swap out the customer's router, thinking it could be bad. The new router gets a new IP, and It temperarlly fixes the issue. I am curious if other users have found a good way to identify this traffic? I am also curious if you have implemented any Block lists that could be shared with the Group that could help stop the traffic? Thanks for any ideas you can share.

Seeking Microsoft AS8075 contact
by John Stitt 05 Jan '26

05 Jan '26

Could someone from Microsoft AS8075 reach out to us off list? We've been having a number of customers complaining because their Xbox is saying it "Can't get a Teredo IP address". Seems to be related to the DNS response the client gets, as we've been able to work around the issue by trying different DNS providers. One of our network admins has been battling this while I've been out on vacation the past two weeks. Some of the customers are able to replicate the issue when using their cell provider, so it's not limited to just our network having this issue. We have some packet captures we can share, and an employee who is able to replicate the issue at their house for further testing. Attempting to contact Microsoft via other routes hasn't gotten him anywhere. Thanks, John Stitt HES energynet

Hey y'all, A collaborative Google Doc was started by Daniel Goulding on "Important Network and Datacenter Papers Everyone Should Read" (https://docs.google.com/document/d/1twMAtoCTx_6AcuD2aocrokLLuCQZMI9Fv9kFJ6Y…) If you have any suggestions, please add them as comments to the document. You can also share them here, and also provide feedback. I have also mentioned this in the Discord (https://discord.nanog.org) for any real-time discussions. Kind regards, Ryan Hamel
