Hi, the tables bellow show the number of /24 IP blocks per AS that are unreachable in an RPKI route origin validating environment (this list is filtered for NL ASNs). I'd encourage everyone to look into the ROAs of affected prefixes (or to ask the customer / IP holder responsible for it). You can use the RPKI validator https://rpki-validator.ripe.net/bgp-preview or https://bgp.he.net (prefix view) to find the specific affected prefixes. If the invalids are expected (i.e. to test ROV) - like Job's prefixes are I suppose - than you can ignore this email (and maybe drop me an email). some more context: https://medium.com/@nusenu/where-are-rpki-unreachable-networks-located-65c7a... kind regards, nusenu +----------+----------------------------------------------------------------+---------------+ | ASN | (announcing) AS Name | /24 netblocks | +----------+----------------------------------------------------------------+---------------+ | AS51088 | A2B - A2B IP B.V. | 16 | | AS15562 | SNIJDERS - Job Snijders | 8 | | AS205333 | ARCADIZ-NL - Arcadiz Networks BV | 4 | | AS50245 | SERVEREL-AS - Serverel Inc. | 3 | | AS12506 | INSPIRING-NETWORKS-BV - Inspiring Networks BV | 3 | | AS60781 | LEASEWEB-NL-AMS-01 - LeaseWeb Netherlands B.V. | 3 | | AS136175 | SERVERHOSH-AS-AP Serverhosh Internet Service | 2 | | AS49453 | GLOBALLAYER - Global Layer B.V. | 2 | | AS49981 | WORLDSTREAM - WorldStream B.V. | 2 | | AS64484 | ASDMZHOST - JUPITER 25 LIMITED | 2 | | AS56630 | MELBICOM-EU-AS - Melbikomas UAB | 1 | | AS43350 | NFORCE - NForce Entertainment B.V. | 1 | | AS206376 | INTELLECTICAINDIA - Intellectica Systems India Private Limited | 1 | +----------+----------------------------------------------------------------+---------------+ Unreachable /48 IPv6 blocks: +----------+-----------------------------+---------------+ | ASN | (announcing) AS Name | /48 netblocks | +----------+-----------------------------+---------------+ | AS202196 | BOOKING-BV - Booking.com BV | 3 | +----------+-----------------------------+---------------+ -- https://twitter.com/nusenu_
