Frontier AS5650 IPv6 Peering
by Nick Olsen 21 May '24

21 May '24

Anyone with a clue from 5650 monitoring this list? I'm in the process of turning up a new transit circuit from 5650 and my account management team has been less than helpful. The normal contacts aren't getting me anywhere. Thank you!

Should FCC look at SS7 vulnerabilities or BGP vulnerabilities
by Sean Donelan 21 May '24

21 May '24

Should FCC focus on SS7 vulnerabilities or BGP vulnerabilities? https://www.404media.co/email/79f7367c-bd3c-4bff-ac9f-85c738d08bec/ https://www.fcc.gov/ecfs/document/10427582404839/1 Additional comments from Kevin Briggs: "I have seen what appears to be reliable information related to numerous other exploits based on SS7 and Diameter that go beyond location tracking. Some of these involve issues like (1) the monitoring of voice and text messages, (2) the delivery of spyware to targeted devices, and (3) the influencing of U.S. voters by overseas countries using text messages."

Cogent-TATA peering dispute?
by Ben Cartwright-Cox 19 May '24

19 May '24

It would appear that ( as of yesterday ) some but not all BGP routes between Cogent and TATA are gone. >From my own observations it seems like all TATA Routes in APAC and India are now not visible from cogent connections/customers. There's also a report of a cogent support ticket response from reddit (so a small dump truck of salt might be warranted) that suggests it’s a cogent instigated depeering ( https://www.reddit.com/r/networking/comments/1cu13bv/cogent_depeering_tata/ ) > Dear customer, > For many years, Cogent has been trying to work with TATA on ensuring sufficient connectivity in each global region the networks operate per normal peering practices. Despite Cogent’s repeated requests, TATA has consistently refused to establish connectivity in Asia, taking advantage of Cogent’s good faith efforts while also ensuring sub-standard service to both companies customers. No amount of good will and good faith augments on Cogent’s part has brought TATA any closer to the negotiating table for a resolution to the lack of connectivity in Asia. This one-sided situation has become untenable and as a result, Cogent has elected to start the process of restricting connectivity to TATA. >From bgp.tools point of view, It seems that TATA has routes to cogent in some places, but cogent does not have all TATA India/APAC routes. Also poking around on RIPE Atlas suggests that for a non-zero amount of networks in India the C DNS Root Server that cogent runs is inaccessible: https://atlas.ripe.net/measurements/71894623#probes Assuming these assumptions are true, there should be around 930 Cogent-Only ASNs and 645 TATA-Only ASNs who now have questionable reachability to each other. My (bgp.tools) visibility for TATA has always been quite slim, especially in APAC, what do other people see on their TATA sessions?

Mailing list SPF Failure
by Scott Q. 17 May '24

17 May '24

Anyone else getting SPF failures on all messages sent to the list ? I see them all originating from 50.31.151.76 but nanog.org's SPF record doesn't list that as allowed.

Q: is RFC3531 still applicable?
by Adam Thompson 16 May '24

16 May '24

Not an IPv6 newbie by any stretch, but we still aren't doing it "at scale" and some of you are, so... For a very small & dense (on 128-bit scales, anyway) network, is RFC3531 still the last word in IPv6 allocation strategies? Right now, we're just approaching it as "pick the next /64 in the range", as it all gets aggregated at the BGP border anyway, and internally if I really try hard, I might get to 200 subnets someday. Is there any justification for the labour in doing something more complex like center-allocation in my situation? Worrying about allocation strategies seems appropriate to me if you have 100,000 subnets, not 100. Opinions wanted, please. -Adam Adam Thompson Consultant, Infrastructure Services MERLIN 100 - 135 Innovation Drive Winnipeg, MB R3T 6A8 (204) 977-6824 or 1-800-430-6404 (MB only) https://www.merlin.mb.ca<https://www.merlin.mb.ca/> Chat with me on Teams<https://teams.microsoft.com/l/chat/0/0?users=athompson@merlin.mb.ca>

Just assign > /64s. A single /64 subnet has 18,446,744,073,709,551,616 host > addresses. It is enough. Period. With IPv6 when you think of assignment to end-user, it's better to think in terms of 'use case' rather than number of hosts within a single network. As a residential user I might have wifi, voip, TV, CCTV,,... each of them can use its own prefix. As a bare metal user in a datacenter , I might have different needs when I build any internal networks. As a corporate user, I think this one is the more obvious. The only end-user who might stick with a single /64 is - 1 smartphone - 1 VM -- Willy Manga
