2018-06 Can we have additional methods for validation or have the NCC not be so obstinate on doing removals
by Delacruz, Anthony B 29 May '19

29 May '19

I'm very appreciative for the efforts here to clean out the IRR. I am a major resource holder with IP's and ASN's from all the RIR and we also run an IRR. I am often frustrated that when I open a ticket with the NCC and even place an entry in whois on space I own that is clearly listed wrong in RIPE-NONAUTH IRR that it is a multi week struggle to get entries removed and they have me chase the contact that put in the entry which is often not responsive. Since not all of my space right now is easily taken care of using RPKI for this, I would very much like to suggest additional methods be available for the NCC to consider a valid request for removal. Other IRR's I work with we usually send the request from the MNT or POC that is on the account/orgid/lir listed with the RIR and in some cases I go as far as to set whois on the blocks with various messages like "please clear, IRR BAD, Hijacked, Recovered Space" and several other messages to make it understood the range has some reason we don't want an IRR entry to be showing for it. Many of the dozen other IRR are quick and a pleasure to work with but the NCC is not ever easy or prompt on the cases I have put in.

Fw: [db-wg] Suggestion further validity-checking
by ripedenis＠yahoo.co.uk 28 May '19

28 May '19

Colleagues We have had a suggestion (with some support) on the DB-WG mailing list about deprecating the "holes:" attribute in ROUTE(6) objects. Perhaps the Routing WG could consider if this attribute has any value in the RIPE Database. cheersdenis co-chair DB-WG ----- Forwarded message ----- From: Nick Hilliard via db-wg <db-wg(a)ripe.net>To: Edward Shryane <eshryane(a)ripe.net>Cc: "db-wg(a)ripe.net" <db-wg(a)ripe.net>Sent: Tuesday, 28 May 2019, 13:30:30 CESTSubject: Re: [db-wg] Suggestion further validity-checking Edward Shryane via db-wg wrote on 28/05/2019 12:12: > Unfortunately, no cleanup was done when this rule was implemented, > but in recent times we try to do this.

It's used for 643 out of 302354 route: objects and 40 out of 28803 route6: objects, i.e. ~0.2% and 0.1% respectively. The complexity associated with handling it is substantial and most tools simply ignore it. Nick

RPKI Route Origin Validation - Africa
by Mark Tinka 21 May '19

21 May '19

Thanks, Job. So we hit the below issue in the first week: https://lists.uknof.org.uk/cgi-bin/mailman/private/uknof/2019-April/006470.… Also in the first week, 2 customers reported an issue accessing some IP addresses in Europe and the U.S. These turned out to be broken ROA's which took a while to fix. Finding the right person in the remote networks (one being a cloud provider) was a bit of a mission. But eventually, it got fixed. Recently, AMS-IX sent out 2 notifications for Invalid ROA's of some of our customers. It was also an incorrect ROA setup, which was fixed in 2 days, each. We are now rolling out ROV to our downstream BGP customers. I don't expect any issues as: - Most of our customers will have a NotFound state. - We will manually check each customer's setup before we turn on ROV for them. We should be done within 3 months or so.

RPKI Route Origin Validation - Africa
by Ben Maddison 21 May '19

21 May '19

Hello all. In November 2018 during the ZAPF (South African Peering Forum) meeting in Cape Town, 3 major African ISP's announced that they would enable RPKI-based ROV (Route Origin Validation), including dropping Invalid routes as part of efforts to improve Internet routing security, on the 1st April, 2019. On the 1st of April, Workonline Communications (AS37271) enabled ROV and began dropping Invalid routes. This applies to all eBGP sessions, both IPv4 and IPv6. On the 5th of April, SEACOM (AS37100) enabled ROV and began dropping Invalid routes. This applies to eBGP sessions with public peers, private peers and transit providers, both for IPv4 and IPv6. eBGP sessions toward downstream customers will follow in 3 months time. Implementation at the third ISP has yet to be completed. We are sure they will communicate with the community when they are ready to do so. Please note that for the legal reasons previously discussed in various fora, neither Workonline nor SEACOM are utilising the ARIN TAL. As a result, any routes covered only by a ROA issued under the ARIN TAL will fall back to a status of Not Found. Unfortunately, this means that ARIN members will not see any improved routing security for their prefixes on our networks until this is resolved. We will each re-evaluate this decision if and when ARIN's policy changes. We are hopeful that this will happen sooner rather than later. If you interconnect with either of us and believe that you are experiencing any routing issues potentially related to this new policy, please feel free to reach out to either: - noc(a)workonline.africa - peering(a)seacom.mu Workonline Communications and SEACOM hope that this move encourages the rest of the ISP community around the world to ramp up their deployment of RPKI ROV and begin dropping Invalid routes. We appreciate the work that AT&T and others have carried out in the same vein. In the mean time, we are happy to answer any questions you may have about our deployments. Thanks, Mark Tinka (SEACOM) & Ben Maddison (Workonline Communications).

RPKI Planned Downtime
by Alun Davies 09 May '19

09 May '19

Dear colleagues, We’ll be running an upgrade on our infrastructure on Monday, 13 May from 10:30 (UTC+2). During the time it takes to carry out the upgrade, the RSYNC and RRDP repositories will be accessible, but the up down protocol, the RPKI user interface on my.ripe.net <http://my.ripe.net/>, and REST API will be unavailable. We expect the upgrade to take no longer than an hour. We apologise in advance for any inconvenience that might be caused by this. https://www.ripe.net/support/service-announcements/rpki-planned-downtime-1/ <https://www.ripe.net/support/service-announcements/rpki-planned-downtime-1/> Kind regards, Alun Davies Communications Officer RIPE NCC

New on RIPE Labs: 768k Day. Will it Happen? Did it Happen?
by Mirjam Kuehne 25 Apr '19

25 Apr '19

Dear colleagues, Will there be a 768k day similar to the 512k day we saw a few years ago? In this RIPE Labs article we show what we currently see in the RIPE Routing Information Service (RIS): https://labs.ripe.net/Members/emileaben/768k-day-will-it-happen-did-it-happ… Kind regards, Mirjam Kühne RIPE NCC

New on RIPE Labs: BGP Zombies
by Mirjam Kuehne 24 Apr '19

24 Apr '19

Dear colleagues, When withdrawing an IP prefix from the Internet, an origin network sends BGP withdraw messages, which are expected to propagate to all BGP routers that hold an entry for that IP prefix in their routing table. Yet network operators occasionally report issues where routers maintain routes to IP prefixes withdrawn by their origin network - BGP zombies. Please find more details on RIPE Labs: https://labs.ripe.net/Members/romain_fontugne/bgp-zombies Kind regards, Mirjam Kühne RIPE NCC

ACM BuildSys 2019 - Nov. 13-14 - New York City - Call for Workshops/Papers Reminder and Call for Posters/Demos/PhD Colloquium
by Mostafa Mirshekari 18 Apr '19

18 Apr '19

Dear Colleagues, Just a couple of reminders about the ACM International Conference on Systems for Energy-Efficient Built Environments, Cities, and Transportation (*ACM BuildSys*) Call for Workshops/Papers and announcement of the Call for Posters/Demos, Short Papers, and the Doctoral Colloquium. The conference will be held Nov. 13-14 in New York City, NY, USA. *Call for Workshops Reminder - Approaching Soon!* BuildSys features co-located workshops on new trends or emerging topics of interest to the BuildSys research community. BuildSys 2019 Call for Workshops: http://buildsys.acm.org/2019/workshops.html <http://trackmyemails.org/1c92e995d1f999d35dde2f1bac182f67/c14c50cdefdcc0a68…> *Workshop Proposal Important Dates* Proposal submission deadline: *April 20th, 2019 - Approaching soon!* Notification: *April 28th, 2019 * For Workshop Proposals, please submit your proposal in PDF format via email directly to Semiha Ergan (semiha(a)nyu.edu) and Dan Wang ( dan.wang(a)polyu.edu.hk). Only complete proposals with all required information will be considered. -------- *Call for Papers Reminder* We solicit three types of original submissions: - Regular papers for oral presentation (10 pages) - Notes papers for oral presentation (4 pages) - Abstract papers for short oral and optional poster presentations (2 pages) - **NEW Type of Paper Submission Option this Year** Notes papers are 4-page papers intended to discuss preliminary research results, advocate new research directions, describe public software or datasets, or present short projects that do not warrant a 10-page paper. Notes papers serve, in part, to encourage younger researchers and research teams entering this field of research to share their work. We also encourage Notes paper submissions from industry participants that may not be able to devote resources to a full paper. While Notes papers are not expected to have extensive evaluations, they will be reviewed based on the novelty of their ideas, potential for impact, and quality of presentation. This year we will also have abstract only papers, where the presentation will include a very short oral and an optional poster presentation. The abstract papers will be reviewed by a subset of reviewers and focus on the novelty of the ideas and to encourage new topic areas in BuildSys. BuildSys 2019 Call for Papers: http://buildsys.acm.org/2019/cfp.html <http://trackmyemails.org/1c92e995d1f999d35dde2f1bac182f67/c14c50cdefdcc0a68…> *Paper Submission Important Dates* Abstract Registration: June 15, 2019, AOE Paper Submission: June 22, 2019, AOE. (No further extension will be granted) Paper Notification: August 1st, 2019, AOE Submission site: TBD -------- *Call for Posters/Demos Announcement* BuildSys 2019 welcomes exciting demonstrations of novel technologies, applications, and hardware for the built environment as well as posters showing promising early work. We seek participation from both industry and academia for demonstrations and posters. Selection of demonstration and posters will be based on a short abstract, evaluated based on technical merit and innovation as well as the potential to stimulate interesting discussions and exchange of ideas at the conference. The demo and poster session is a great forum to share your early stage work to the broader audience. Accepted abstracts will appear in the regular conference proceedings. At least one author of every accepted demonstration or poster abstract is required to register and attend the conference. BuildSys 2019 Call for Posters/Demos: http://buildsys.acm.org/2019/posters.html <http://trackmyemails.org/1c92e995d1f999d35dde2f1bac182f67/c14c50cdefdcc0a68…> *Poster abstract*Poster abstracts should report on research work where at least some preliminary results are available, but they need not necessarily describe completed work. An easel will be provided for all posters. All poster abstract submissions must strictly adhere to the formatting guidelines specified below. *Demo abstract*Demo abstracts should describe both the technology being showcased as well as the user experience of the demo. Tables, power, and wireless connectivity will be provided. If a demo requires additional special arrangements, please describe them clearly in your submission using a separate third page (not part of the technical content of the abstract). All demo abstract submissions must strictly adhere to the formatting guidelines specified below. The authors of the accepted demos will be invited to submit an optional short video together with the camera-ready version of the abstract. *Poster/Demo Important Dates* Submission Deadline: August 10, 2019, 11:59:59pm AOE Notification of acceptance: August 19, 2019, 11:59:59pm AOE Camera-ready abstract: September 6, 2019, 11:59:59pm AOE Submission site: TBD -------- *Call for Doctoral Colloquium (PhD Forum) **Announcement* The Doctoral Colloquium of BuildSys 2019 seeks to provide a friendly, supportive, and constructive environment where PhD students can present their research in progress for an open discussion guided by a panel of experienced researchers. The Doctoral Colloquium will be structured as a series of short presentations by the students followed by individual discussions, feedback, and advice from the panel. Students with the most inspiring topics will also be invited to present a poster during the main conference to leverage further interaction with BuildSys attendees. Current PhD students in the early stages of their career are encouraged to submit a 2-page research summary describing the work in progress and including a 100-word abstract. Things to consider for inclusion in the research summary might be: the expected contribution to the field; the original idea or thesis statement; the problem domain and the specific problem addressed; a brief overview of related work; the methodological approach; research carried out and results so far. The abstract should also include a one-paragraph biography of the student, including the names and affiliations of the research advisor(s), and expected date of dissertation submission. The student should be the sole author, although contributions of the advisor and others should be acknowledged. The Doctoral Colloquium committee will review submissions to ensure quality, relevance, and potential benefit from attendance. Authors of accepted submissions are expected to participate in person to the Doctoral Colloquium. There will be no separate registration fee for the Doctoral Colloquium. BuildSys 2019 Call for Doctoral Colloquium: http://buildsys.acm.org/2019/doctoral.html <http://trackmyemails.org/1c92e995d1f999d35dde2f1bac182f67/c14c50cdefdcc0a68…> *Doctoral Colloquium Program* The BuildSys Doctoral Colloquium will be held in conjunction with the SenSys Doctoral Colloquium to enable students from both communities to interact and receive constructive feedback on their work from a diverse set of panelists.

Route object creation authorization
by Havard Eidnes 16 Apr '19

Hi, it looks like "things happened while I wasn't watching"... I've just had a run-in with the route object authorization rules as presently implemented in the RIPE database. I found the following flow chart documenting the authorization procedure: https://www.ripe.net/support/training/material/Routing-Security-Training-Co… which is referenced from https://www.ripe.net/manage-ips-and-asns/db/support/managing-route-objects-… The question I have is this: What is the policy reason for having a pre-existing route object play any role in authenticating the creation of a new route object, so that it in effect overrides any mnt-routes: fields of the corresponding inetnum object for the address space holder? When a customer who has his own address space and controls his own inetnum object, but lets his current ISP originate the route with the ISP's ASN as origin, but wants to move to another ISP, given the current rules, the current ISP is able to hold the customer hostage by refusing to create a new route object with a different ASN as origin. I would not have thought it was RIPE's role to raise and enforce such a barrier? I also can't quite comprehend why a route object would need the "mnt-routes" or "mnt-lower" attributes -- in an inetnum object I can understand the semantics of those, but in a route? Best regards, - Håvard

Analysis tool for RIPE Proposal 2018-06
by Job Snijders 01 Apr '19

01 Apr '19

Dear all, I wrote a small tool to help understand the effects if RIPE Policy Proposal 2018-06 is accepted by the community. This is the "Let's use RPKI ROAs to clean up the non-authoritative RIPE-NONAUTH IRR source!"-proposal (source: https://www.ripe.net/participate/policies/proposals/2018-06). The tool can also be used by RIPE NCC staff to validate their implementation or help their impact analysis. Quick reminder: this proposal does *not* impact any RIPE Managed space, this does *not* impact IP space for which no RPKI ROAs have or can be created, and it does *not* impact route objects where the route object and the RPKI ROA are match each other. Currently there are 793 IRR "route:" objects and 17 "route6:" objects that conflict with published RPKI ROAs. Out of those ~ 800, roughly 33 prefixes are visible in the BGP DFZ as exact matches between what is registered in RIPE-NONAUTH and in BGP (note: this means these 33 announcements are "RPKI Invalid", and the likes of Cloudflare / AT&T probably aren't accepting those announcements anyway)... You can install the tool through 'pip3 install ripe-proposal-2018-06', or download the source from https://github.com/job/ripe-proposal-2018-06 Usage example: $ ripe-proposal-2018-06 -a 7018 Downloading https://rpki.gin.ntt.net/api/export.json Downloading https://ftp.ripe.net/ripe/dbase/split/ripe-nonauth.db.route.gz INVALID! The 99.122.224.0/21AS1273 RIPE-NONAUTH route object has conflicts: route: 99.122.224.0/21 descr: route for customer Akamai International origin: AS1273 created: 2008-09-08T14:40:49Z last-modified: 2018-09-04T15:54:45Z source: RIPE-NONAUTH mnt-by: CW-EUROPE-GSOC Above non-authoritative IRR object is in conflict with this ROA: ROA: 99.112.0.0/12, MaxLength: 12, Origin AS7018 (ARIN) Note that AT&T has no method of getting this erroneous "route:" object removed, other than to beg & plead with maintainer 'CW-EUROPE-GSOC'. We're working on an updated version of RIPE Policy Proposal 2018-06 to incorporate feedback from the community, such as an attempt to send notifications and a grace period before the object is actually removed. All in all it appears that if this policy proposal is deployed *now*, the operational impact is virtually non-existent; and after deploying this the global community has an industry-standard way to get rid of stale proxy route registrations. With every published ROA the "RIPE-NONAUTH" source becomes cleaner! Kind regards, Job

RPKI validator 3: initial sync regression?
by nusenu 22 Mar '19

22 Mar '19

Hi, lately with validator 3 version > 370 it felt like rpki-validator 3 is less reliable and taking longer to download RPKI repository data (especially RIPE's) when starting for the first time when compared to older version (313) where it probably took less than 5 minutes after starting it to have the data for all regions. I reproduced this consistently. Can you think of anything that caused this? Does anyone else see this as well? Unfortunately I didn't find any changelogs and it is not obvious what version relates to what git commit since there are no git tags in the github repo. It would be great to have changelogs or git tags. thank you, nusenu -- https://twitter.com/nusenu_ https://mastodon.social/@nusenu
