What to fix

  1. Warning

    9 of 9 announced prefixes have no ROA (RPKI not found): 177.152.144.0/21, 177.152.144.0/22, 177.152.148.0/22, 177.152.148.0/23, 2804:4c6c:100::/40 (+4).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS52542 and a max length equal to the prefix length:

    177.152.144.0/21 AS52542 max-length /21
177.152.144.0/22 AS52542 max-length /22
177.152.148.0/22 AS52542 max-length /22
177.152.148.0/23 AS52542 max-length /23
2804:4c6c:100::/40 AS52542 max-length /40
2804:4c6c:200::/40 AS52542 max-length /40
2804:4c6c:300::/48 AS52542 max-length /48
2804:4c6c:301::/48 AS52542 max-length /48
2804:4c6c::/32 AS52542 max-length /32

  2. Warning

    4 of 9 announced prefixes have no IRR route object: 2804:4c6c:300::/48, 2804:4c6c:301::/48, 2804:4c6c:200::/40, 2804:4c6c:100::/40.

    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 AS52542 in your RIR’s IRR database (or RADB).

    route6: 2804:4c6c:300::/48
origin: AS52542

route6: 2804:4c6c:301::/48
origin: AS52542

route6: 2804:4c6c:200::/40
origin: AS52542

  3. Warning

    No IRR as-set is listed.

    Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

    Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
