I’m having zero luck getting an issue with Charter/Spectrum escalated and I’m hoping to find a sympathetic ear that can contact me off-list. Thanks, Daniel

Routed optical networks
by Etienne-Victor Depasquale 15 May '23

15 May '23

Hello folks, Simple question: does "routed optical networks" have a clear meaning in the metro area context, or not? Put differently: does it call to mind a well-defined stack of technologies in the control and data planes of metro-area networks? I'm asking because I'm having some thoughts about the clarity of this term, in the process of carrying out a qualitative survey of the results of the metro-area networks survey. Cheers, Etienne -- Ing. Etienne-Victor Depasquale Assistant Lecturer Department of Communications & Computer Engineering Faculty of Information & Communication Technology University of Malta Web. https://www.um.edu.mt/profile/etiennedepasquale

Major changes to ARIN RPKI functionality (Fwd: [arin-announce] New Features Added to ARIN Online)
by John Curran 13 May '23

13 May '23

NANOGers - If you are using (or interested in) RPKI, please review the attached announcement regarding the rollout of significant changes to RPKI functionality at ARIN. FYI, /John John Curran President and CEO American Registry for Internet Numbers Begin forwarded message: From: ARIN <info(a)arin.net> Subject: [arin-announce] New Features Added to ARIN Online Date: May 13, 2023 at 12:58:50 PM EDT To: "arin-announce(a)arin.net" <arin-announce(a)arin.net> ARIN is pleased to present the latest version of ARIN Online, including improvements, new features, and updates. Full release notes are included at the end of this message. All ARIN systems have been restored and are now operating normally. We thank you for your patience. If you have additional questions, comments, or issues, please submit an Ask ARIN ticket using your ARIN Online account or contact the Registration Services Help Desk by phone Monday through Friday, 7:00 AM to 7:00 PM ET at +1.703.227.0660. Regards, Mark Kosters Chief Technology Officer American Registry for Internet Numbers (ARIN) Release Notes - For customers of the Hosted RPKI (Resource Public Key Infrastructure) service, significant changes have been made, especially to the management of ROAs (Route Origin Authorizations) in ARIN Online. - We have removed the requirement for users to generate a public/private key pair to create Resource Certificates and ROAs. - Signing up for Hosted RPKI is no longer a ticketed process. - Creating ROAs is no longer a ticketed process. Created ROAs will be returned immediately and available in the next repository delta. - All ROAs in the repository created using ARIN Online will auto renew. - We have streamlined the top navigation menu of the RPKI pages in ARIN Online. - For customers of the Hosted RPKI, changes have been made to the RESTful API for managing ROAs. - It is now possible to create and delete multiple ROAs through a single API call. - ROAs created with the new API will auto renew. - All ROAs in the repository created using the previous API will not auto renew and will retain their original expiration date. - We have created a new URL associated with the new RESTful API calls for managing ROAs. We will maintain the old API endpoints to prevent existing users from having to change their scripts. - We will migrate all existing ROAs in the RPKI repository created using the ARIN Online interface to auto renew. ROAs generated using the previous RESTful API will not be migrated to auto renew and will retain their existing expiration date. To take advantage of auto renew, ROAs created with the previous RESTful API must be replaced with ones created using the newly released RESTful API. - Some changes have been made to the management of Delegated RPKI. - Signing up for Delegated RPKI service is no longer a ticketed process. - Updating the child_request document is no longer a ticketed process. - We have made stylistic updates in ARIN Online to provide a more consistent experience across devices and operating systems. _______________________________________________ ARIN-Announce You are receiving this message because you are subscribed to the ARIN Announce Mailing List (ARIN-announce(a)arin.net) Unsubscribe or manage your mailing list subscription at: https://lists.arin.net/mailman/listinfo/arin-announce Please contact info(a)arin.net if you experience any issues.

Best Linux (or BSD) hosted BGP?
by Bryan Fields 11 May '23

11 May '23

I know best subjective, but I'm looking at a project to announce some IP space that's between uses now and see what's there. I'm planing to run a flow logger and ntop on the VM and see what is coming in if anything. I'm looking at the options for BGP out there, and there's quite a few (other than running a VM with a router doing BGP), but most data I've seen is focused on scale and filtering use, or RPKI. My use case is a bit different, and I can't find any best practices for this use case from what I've found. That said, is there a better solution other than linux/ntop/ipt-netflow? -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net

Aptum refuses to SWIP
by Lyndon Nerenberg (VE7TFX/VE6BBM) 10 May '23

10 May '23

It seems Aptum has decided they will no longer SWIP any of their address space. I've been trying to get a SWIP for a /48 that we were allocated in 2017, but they refuse. And I also see they have pro-actively gone in and un-SWIPed both our /24s. Since you are ignoring my tickets about this, maybe somebody from Aptum would care to speak up in public and defend this "policy?" --lyndon

webex.com DNS Contact - Possibly Broken DNSSEC?
by Reuben Farrelly 10 May '23

10 May '23

Does anyone know of a contact of someone (presumably at Webex/Cisco) who can take a look at the DNS for webex.com? It has been for some time now, logging a lot of DNSSEC warnings on my resolver: dnssec: validating external-media75.public.wnrtm-a-2.prod.infra.webex.com/NSEC: no valid signature found: 1 Time(s) dnssec: validating external-media75.public.wsinm-a-3.prod.infra.webex.com/NSEC: no valid signature found: 1 Time(s) dnssec: validating external-media78.public.wbomm-a-2.prod.infra.webex.com/NSEC: no valid signature found: 1 Time(s) dnssec: validating external-media8.public.wnrtm-a-2.prod.infra.webex.com/NSEC: no valid signature found: 1 Time(s) (and a whole lot more hostnames in the same domain). Some basic DNSSec analysis indicates something in the middle of the trust chain is broken: https://dnssec-analyzer.verisignlabs.com/external-media26.public.wjfkm-a-3.… It looks to me like the subdomains have DS records but the other parts of the subdomain don't and I guess there's no point in having DS records on host records, if the parent domain doesn't have them too. I wouldn't bother if it was one or two entries, but it looks like the whole domain is affected and this probably is a fairly widely utilised domain. Thanks, Reuben
