Dear colleagues, Following the announcement of our plans to debogonise 2a10::/12, we have now shared the results of the tests we've been carrying out to check the usability of address space in this block. Read all about it on RIPE Labs: https://labs.ripe.net/Members/emileaben/the-debogonisation-of-2a10-12 Kind regards, Mirjam Kühne RIPE NCC

De-bogonising 2a10::/12
by Emile Aben 16 Jan '20

16 Jan '20

Dear colleagues, We have now started de-bogonising 2a10::/12! As part of this, we are announcing a couple of prefixes out of 2a10::/12 from AS12654 (RIPE's Routing Information Service, RIS). Pingable targets have been configured in these prefixes, and we invite network operators to test for themselves whether this address space is reachable. The simplest way to do this would be to perform a ping6 to 2a10:4::1 . Using RIPE Atlas and RIS, we will also be carrying out our own tests in order to investigate connectivity and filtering for this address space. We plan to share our results with the RIPE community via RIPE Labs within the next few days. For those who want to do other testing, beyond the basic test described above, we have a total of 8 targets available for this, with 2 different prefix lengths and all variations of having ROUTE objects in the RIPE DB and/or ROAs. 2a10:3:4::1 /48 ROUTE object + ROA 2a10:3:5::1 /48 no ROUTE object + ROA 2a10:3:6::1 /48 ROUTE object + no ROA 2a10:3:7::1 /48 no ROUTE object + no ROA 2a10:4::1 /32 ROUTE object + ROA 2a10:5::1 /32 no ROUTE object + ROA 2a10:6::1 /32 ROUTE object + no ROA 2a10:7::1 /32 no ROUTE object + no ROA Kind regards, Emile Aben RIPE NCC

De-bogonising 2a10::/12
by Nikolas Pediaditis 08 Jan '20

08 Jan '20

Dear colleagues, A few months ago the RIPE NCC became the first RIR to receive an additional /12 IPv6 allocation (2a10::/12) from IANA. We will soon begin to delegate space from this IPv6 block to LIRs. Prior to this, in order to improve routability and minimise the risk of filtering, the RIPE NCC will perform several de-bogonising activities in the next few weeks. We plan to start announcing the full /12, as well as a few /32 or longer blocks out of 2a10::/12 from AS12654 (RIPE Routing Information System (RIS)), within the next few days. We will analyse data from RIS and RIPE Atlas and we plan to write up an analysis around this effort. We want to remind everybody to update their bogon filters and allow routes originating from 2a10::/12 in their network. Kind regards, Nikolas Pediaditis Registration Services and Policy Development Manager RIPE NCC

2018-06 Proposal Implemented (RIPE NCC IRR Database Non-Authoritative Route Object Clean-up)
by Edward Shryane 06 Jan '20

06 Jan '20

Dear Working Group, The RIPE NCC Database team have now implemented the 2018-06 proposal (now ripe-731), "RIPE NCC IRR Database Non-Authoritative Route Object Clean-up". We plan to deploy this to production on Wednesday 15th January. A nightly job will run from that evening onwards. We expect approximately 965 route objects will be initially marked for cleanup (which will happen 2 weeks after that). Regards Ed Shryane RIPE NCC > > From: Petrit Hasani <phasani(a)ripe.net> > Subject: [policy-announce] 2018-06 Proposal Accepted (RIPE NCC IRR Database Non-Authoritative Route Object Clean-up) > Date: 6 November 2019 at 16:03:18 GMT+1 > To: policy-announce(a)ripe.net > > Dear colleagues, > > Consensus has been reached on 2018-06, "RIPE NCC IRR Database Non-Authoritative Route Object Clean-up". > > This proposal aimed at creating a process to delete a non-authoritative object stored in the RIPE IRR, if it conflicts with an RPKI ROA. > > You can find the full proposal at: > https://www.ripe.net/participate/policies/proposals/2018-06 > > The new RIPE Document is called ripe-731 and is available at: > https://www.ripe.net/publications/docs/ripe-731 > > We estimate that this proposal will take around two to three months to fully implement. > > We will send another announcement once the implementation is complete and the new procedures are in place. > > Thank you to everyone who provided us with your input. > > Kind regards, > > -- > Petrit Hasani > Policy Officer > RIPE NCC > > > > >

Example: Facinating. It would be even more facinating to have someone from RIPE NCC come and explain to us all how it came to pass that something on the order of an alleged 490 thousand IPv4 addresses got transferred, allegedly illicitly, from a Russian company to a Czech company, AND what rules and standard procedures were followed in order to transfer these back to the Russian company... ... but I also asked for a unicorn for Christmas and I didn't get that either. :-) I guess that when Russia comes knocking, RIPE NCC submissively complies. I can only wish that they would do the same for me. Regards, rfg
