What to fix

  1. Warning

    4 of 4 announced prefixes have no ROA (RPKI not found): 45.173.236.0/22, 2804:5b64:8000::/33, 2804:5b64::/32, 2804:5b64::/33.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS268840 and a max length equal to the prefix length:

    45.173.236.0/22 AS268840 max-length /22
2804:5b64:8000::/33 AS268840 max-length /33
2804:5b64::/32 AS268840 max-length /32
2804:5b64::/33 AS268840 max-length /33

    Open in RPKI / ROA validator Guide

  2. Warning

    1 of 4 announced prefixes have no IRR route object: 2804:5b64:8000::/33.

    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 AS268840 in your RIR’s IRR database (or RADB).

    route6: 2804:5b64:8000::/33
