What to fix

  1. Problem

    2 of 118 announced prefixes are RPKI invalid: 106.225.204.0/23, 115.153.228.0/24.

    A ROA covers them but does not allow this origin or prefix length, so networks that filter (most large ones do) drop these routes.

    Fix: Fix the ROAs (origin AS and max length) at your RIR, or stop announcing the routes.

    Open in RPKI / ROA validator Guide

  2. Warning

    19 of 118 announced prefixes have no IRR route object: 106.225.198.0/23, 115.153.228.0/24, 106.225.208.0/21, 106.225.136.0/21, 106.225.144.0/24 (+14).

    Many networks build their prefix filters from IRR data; without route objects some of them drop the routes.

    Fix: Create route (IPv4) and route6 (IPv6) objects with origin AS134238 in your RIR’s IRR database (or RADB).
