Even without anycast, an ECMP shouldn't hash on the ECN bits. Doing so will split the flow over multiple paths; avoiding that is the whole point of doing the flow-based hashing in the first place. Anycast "only" turns a potential degradation of TCP performance into a hard failure... :) -Toke

Team, We are having issues in our Virginia US office & it shows geolocation in all browsers as Canada instead of US region when we access news.google.com in our PC. Our public ip is 129.46.232.65. This issue is being observed for more than 2 month. Can you help to whom we can contact to resolve the issue. Regards, Raja

Zayo woes
by JASON BOTHE 14 Nov '23

14 Nov '23

Does anyone know what’s happening at Zayo? Tickets are taking weeks and months to get resolved, much less get a tech assigned to them. The folks answering the noc phone are mere order takers and are only reading from a script, manager on duty/escalation lines go to voicemail. If anyone can help get to a human in the transport group, that would be great. I’ve given up all hope at this point. Appreciated. Jason

constraining RPKI Trust Anchors
by Job Snijders 12 Oct '23

12 Oct '23

Dear all, Two weeks ago AFRINIC was placed under receivership by the Supreme Court of Mauritius. This event prompted me to rethink the RPKI trust model and associated risk surface. The RPKI technology was designed to be versatile and flexible to accommodate a myriad of real-world deployment scenarios including multiple trust anchors existing, inter-registry transfers, multiple transports, and permissionless innovation for signed objects, for example. All good and well ... but ofcouse there is a fine print. :-) Over the years various people have expressed astonishment about each RIR having issued so-called 'all-resources' (0.0.0.0/0 + ::/0) trust anchor certificates, but this aspect often is misunderstood: the risk is not necessarily in the listing of 'all-resources' itself, it is in the RIR being able to issue an 'all-resources' certificate in the first place. RPKI trust anchor operators indeed can voluntarily reduce the scope of subordinate Internet Number Resources, but just as easily increase the scope of their authority. In other words, a trust anchor cannot truly constrain itself. Upon reconsideration on how exactly RPKI hooks into the real world; I concluded trust anchors do not require unbounded trust in order to provide constructive services in the realm of BGP routing security. Some examples: ARIN does not support inter-RIR IPv6 transfers, so it would not make any sense to see a ROA subordinate to ARIN's trust anchor covering RIPE-managed IPv6 space. Conversely, it wouldn't make sense to observe a ROA covering ARIN-managed IPv6 space under APNIC's, LACNIC's, or RIPE's trust anchor - even if a cryptographically valid certificate path existed. Along these lines AFRINIC doesn't support inter-RIR transfers of any kind; and none of the RIRs have authority over private resources like 10.0.0.0/8 or AS 65535. It seems feasible to paint constraints around RPKI trust anchors in broad strokes. Over the last two weeks I've diligently worked with Theo Buehler to research RIR transfer policies, untangle the history of the IANA->RIR and RIR->RIR allocation spaghetti, design & implement a maintainable constraints mechanism for rpki-client(8), and publicly document the concept of applying operator-defined policy to derived trust arcs. Please take a moment to read https://www.ietf.org/archive/id/draft-snijders-constraining-rpki-trust-anch… Your feedback is appreciated. Kind regards, Job

Re: maximum ipv4 bgp prefix length of /24 ?
by Jakob Heitz (jheitz) 05 Oct '23

05 Oct '23

Each unit of mask length increase doubles the size of the table theoretically. About 60% of the table is /24 routes. Just going to /25 will probably double the table size. Not sure I'd like to extrapolate the estimate out to /27. Kind Regards, Jakob ----------------------------------------------------------------------------- Date: Fri, 29 Sep 2023 00:25:55 +0300 From: VOLKAN SAL?H <volkan.salih.06(a)gmail.com> To: nanog(a)nanog.org hello, I believe, ISPs should also allow ipv4 prefixes with length between /25-/27 instead of limiting maximum length to /24.. I also believe that RIRs and LIRs should allocate /27s which has 32 IPv4 address. considering IPv4 world is now mostly NAT'ed, 32 IPv4s are sufficient for most of the small and medium sized organizations and also home office workers like youtubers, and professional gamers and webmasters! It is because BGP research and experiment networks can not get /24 due to high IPv4 prices, but they have to get an IPv4 prefix to learn BGP in IPv4 world. What do you think about this? What could be done here? Is it unacceptable; considering most big networks that do full-table-routing also use multi-core routers with lots of RAM? those would probably handle /27s and while small networks mostly use default routing, it should be reasonable to allow /25-/27? Thanks for reading, regards..
