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
