What to fix

  1. Warning

    1 of 3 announced prefixes have no ROA (RPKI not found): 2620:105:c000::/48.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS7767 and a max length equal to the prefix length:

    2620:105:c000::/48 AS7767 max-length /48

    Open in RPKI / ROA validator Guide

  2. Warning

    2 of 3 announced prefixes have no IRR route object: 2620:105:c000::/48, 208.185.238.0/24.

    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 AS7767 in your RIR’s IRR database (or RADB).

    route6: 2620:105:c000::/48
origin: AS7767

route: 208.185.238.0/24
origin: AS7767
