Spectrum & GRE
by Christopher Aloi 15 May '25

15 May '25

Hey All, Hoping someone can lend a hand here. I have ~ 1k customers running GRE tunnels back to me for VoIP. Over the last three weeks these tunnels have started to break at a rate of 3-5 per day. We've narrowed it down to customers using specific Spectrum routers (rac2v1s and rac2v2s). I am still able to access the public IP but the tunnel drops and will not come back up. The fix has been to reconfigure as VPN or have the CPE router replaced with a rac2v1k. I have been unable to get anyone to listen to me at Spectrum as these accounts are owned by the customer and I can't prove a systemic issue. I have a list of accounts that have been impacted. Has anyone else encountered this? Any contacts at Spectrum that might listen to me? I am fearing all of these tunnels will go down at some point. Thanks, Chris

3 Netblocks
by info＠netstyle.io 15 May '25

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hello, Years ago I was mentioned in this mailing list regarding "unauthorized use of ip netblocks". This was of course false, not 99.99% false, but 100% false. Some of the quotes that have been here: "Cohen is a theft and a crook" "Cohen sits with impunity in Israel" "Any half brain..." "I have a receipt of the Brooklin Bridge" "Cohen bribed" I hereby link to a police certificate that I received when I purchased a group of netblocks in 2018: https://limewire.com/d/vQYtW#e3cqcwR4Hz (STA-STATMENT-CHIHUAN.pdf) ASLine Limited (AS137951 & AS18013) leased from us the following 3 netblocks years ago (which are listed in the mentioned above police certificate), then ASLine Limited stopped paying us and kept using those 3 netblocks: 155.159.0.0/16 160.121.0.0/16 168.206.0.0/16 They (ASLine) ignored our emails and phone calls for a very long time. ASLine used tier1 providers that accepted BGP announcements which are related to the 3 netblocks above. Including Cogent (which persistently disconnected me but kept to provide service to ASLine). To verify it you can look at the BGP paths history (from approximately two weeks ago and before it), not the currently, because currently Cogent and other tier1 providers stopped to accept the BGP announcements which are related to above netblocks except for NTT. ASLine cannot create route objects in AFRINIC. The account of ASLine in RADb was suspended. ASLine route objects are only in NTTCOM routing registry and NTT is the only one now accepting BGP announcements which are related to the above 3 netblocks from ASLine. NTT is aware (by AFRINIC) that ASLine is not one of the two disputants that AFRINIC are referring to in their whois of the 3 netblocks. NTT is also aware that according to AFRINIC the disputants are Safren Computer Services, Mega Plastics (Pty) Ltd, The Atomic Energy Board - and Afri Holdings. NTT is claiming that they (NTT) received Letters of Authorizations dated 2024 and valid until 2025 from the other disputants (meaning: Safren Computer Services, Mega Plastics (Pty) Ltd and The Atomic Energy Board). I hereby link to it: https://limewire.com/d/vQYtW#e3cqcwR4Hz (NTT.png) I note that The Atomic Energy Board is a governmental entity in South Africa and that NTT is aware of it. I note that the new owner ASLine Limited in the following 3 emails told me that he was "assured" by the past owner that he will be able to use the 3 netblocks (including the governmental netblock) "for free", I hereby add the 3 links to those 3 emails: https://limewire.com/d/vQYtW#e3cqcwR4Hz (Email1.png) https://limewire.com/d/vQYtW#e3cqcwR4Hz (Email2.png) https://limewire.com/d/vQYtW#e3cqcwR4Hz (Email3.png) In the above link there is also an email communication from the year 2020 with the Atomic Energy Board (AtomicEnergyBoard.pdf) when they wrote that they will pass the matter to their lawyers and to the South African Authorities, they wrote that they will communicate further in this regards - it never happened. I also note that by looking at the saved BGP history of all of the netblocks in the linked police certificate, it is clear that those netblocks were used by many many Autonomous Networks which are not related to the entities that initially received them from IANA, and currently NTT have (according to their own words) a proof that the governmental entity Atomic Energy Board gave a Letter of Authorization to ASLine Limited, dated 2024, while the new owner of ASLine Limited owner (in his own words) wrote that he was "assured" that he can also use that netblock "for free" by the past seller, and when he reached out to the past seller - the past seller refused to take responsibility and claimed that they (the past owner) are not obligated, because they didn't charge anything for those 3 netblocks from the new owner. I simply ask, what is going on here? Because the issue was written in NANOG in many threads, maybe you would be interested to know too. I copy NTT, ASLine, AFRINIC and the emails of the Atomic Energy Board which I have on file. I've decided to be 100% transparent because of the severe damages that have occurred to me and that are occurring to me.

I wonder if this has anything to do with the handling of GRE for tunneling hotspot Wi-Fi traffic from their routers. It wouldn't be the first time an ISP's handling of their own traffic caused problems with a user's traffic, even though it shouldn't.

ARIN Consultation: Hierarchical AS-SET Names
by James Bensley 14 May '25

14 May '25

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi all, I raised a request with ARIN to enforce the use of hierarchical AS-SET names in the ARIN DB moving forward, as is the case in RIPE, APNIC, and LACNIC. ARIN have opened a consultation process, which closes on the 23rd of May. If you would like to see ARIN also adopt the requirement for newly created AS-SETs to have hierarchical names, please visit the following page and contact ARIN to record your support for this request: https://www.arin.net/participate/community/acsp/consultations/2025/2025-1/ With kind regards, James. -----BEGIN PGP SIGNATURE----- Version: ProtonMail wsG5BAEBCgBtBYJoJEmnCZCoEx+igX+A+0UUAAAAAAAcACBzYWx0QG5vdGF0 aW9ucy5vcGVucGdwanMub3JnVr0rmLS4qvSLMtY2CBRvsqBwDgmlr/3T+wYR 5vCgJC0WIQQ+k2NZBObfK8Tl7sKoEx+igX+A+wAAlAcP/3rM+XfpLxIm2iFw LfdKSMqSsRVll+1lUwvGzIGB6YoNvbwfenGURA7uYrsU5rMnYPNGM51grY2d xhKeXMcS55R1FDAM1k365n05cu1g7tezsXYeS/MEvjnbA+HrEZv2xkWq+K9b ChlaXzitweTaF8cF/HgPKMukWZigIbS9yb6TgjBMv20Nr+/3tAG8VtEL9FxE 9Wu601HlN4iNYBS79pOJlDEoU3QE1xZx3UDAjsRTwNebzknu6Ilh4wRSKdMc CLd9BpXScJQFnzjDCE3P4ldRk8GK3LbdtxX6aHGcdmcMPDTdJJPzn1Xp6NDY rx3KzeBsv6UOyiqxqtNr0riiSSv3o6/NkYaN52vjgjcrNulhbmijystE7t1P w1+aN/sOGHHf+X+Y/KR7b4eqW9K/HHNsTRY0ZFfNrYio3oRNhfv2Kl1stY7w XG4PUigTiifO4aNhzvYo+gQw+rylIKlG/JI8wMcHdirpk0dPe4r2Dv3cQgBs PZ+wcm9Q1scDKjIYzFn7sVoNluPiV1J7epyUTdmEwvkp2YFD3YLggnl/9c9F IrMhOAXO6p6ro2xZjb68b04aiRCvRIhRn43FyuOXbA/BBy+alu7VvTsdIJrt AC4PmudMYdeNFeD+fx30ra6GjQhAfDhx9rVxfty1wYeqnEnVPJalbwbpqDC2 iR0Z8Fb5 =f2NW -----END PGP SIGNATURE-----

outages list badly broken, flooding messages
by Glenn McGurrin 12 May '25

I've already received 76 copies of "Re: [Outages-discussion] Lists dead - after action report?" and continue receiving them every few minutes, apologies, 77 copies now, this is clearly badly broken, I do understand this is a volunteer run list, but normally I do want to receive notifications as it's generally important if it's on this list, but currently I'm looking at having to block the list as it's sending my notifications nuts. Also as an aside, I'd hesitated offering this before, not feeling like I was known enough or had enough standing in the community for it to be accepted and used, but if help is needed figuring out the issues, or if it would help the community to have a backup list, running mailman or potentially for added diversity running a different mailing list software, it's been a bit but I've used sympa before as well as mailman to run lists, I'm happy to host a secondary backup list(s) to offer some extra redundancy to the community (or if people really wanted to have someone take over the main I'm willing to, but I'm not asking for that or expecting anyone wants that), I know some mention has been made in a thread somewhere about adding redundancy to the list but nothing about the form of that redundancy. FWIW up to 96 copies now as I write this, it's been going on for about an hour and a half at this point, I held of sending anything initially hoping it would be jumped on and at least the sending shut down even if that meant taking any remaining online part of the list down for now until there was time to fix it, as I get it, it's Sunday, people have plans, etc, at this point all I'd ask to be expedited is shutting it down until such time as people have time to fix it, not for people to abandon plans on a Sunday to root cause this and fully fix it.
