What to fix

  1. Problem

    2 of 7 announced prefixes are RPKI invalid: 103.158.65.0/24, 116.212.177.0/24.

    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

    No IPv6 prefixes announced.

    Networks without IPv6 force their users through NAT64 or leave them unreachable from IPv6-only networks.

    Fix: Get an IPv6 allocation from your RIR (usually free with your IPv4 membership) and announce it.

  3. Warning

    5 of 7 announced prefixes have no ROA (RPKI not found): 38.109.201.0/24, 38.109.226.0/24, 45.178.213.0/24, 103.148.204.0/24, 167.253.45.0/24.

    Without a ROA, networks cannot tell your routes from a hijack.

    Fix: Create a ROA for each at your RIR portal, with origin AS5 and a max length equal to the prefix length:

    38.109.201.0/24 AS5 max-length /24
    38.109.226.0/24 AS5 max-length /24
    45.178.213.0/24 AS5 max-length /24
    103.148.204.0/24 AS5 max-length /24
    167.253.45.0/24 AS5 max-length /24

  4. Warning

    5 of 7 announced prefixes have no IRR route object: 45.178.213.0/24, 38.109.201.0/24, 167.253.45.0/24, 116.212.177.0/24, 38.109.226.0/24.

    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 AS5 in your RIR’s IRR database (or RADB).

    origin: AS5
    
    route: 38.109.201.0/24
