What to fix

  1. Warning

    10 of 28 announced prefixes have no ROA (RPKI not found): 103.229.11.0/24, 192.184.74.0/24, 192.184.75.0/24, 192.184.76.0/24, 192.184.77.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS27281 and a max length equal to the prefix length:

    103.229.11.0/24 AS27281 max-length /24
192.184.74.0/24 AS27281 max-length /24
192.184.75.0/24 AS27281 max-length /24
192.184.76.0/24 AS27281 max-length /24
192.184.77.0/24 AS27281 max-length /24
2620:116:801a::/48 AS27281 max-length /48
2620:116:801b::/48 AS27281 max-length /48
2620:116:801c::/48 AS27281 max-length /48

2620:116:801e::/48 AS27281 max-length /48

  2. Warning

    3 of 28 announced prefixes have no IRR route object: 91.228.72.0/24, 103.229.11.0/24, 91.228.74.0/24.

    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 AS27281 in your RIR’s IRR database (or RADB).

    route: 91.228.72.0/24
origin: AS27281

route: 103.229.11.0/24
origin: AS27281

route: 91.228.74.0/24
origin: AS27281

  3. Warning

    No public NOC, policy or technical contact.

    Other networks use these addresses to set up peering and to reach you during an incident.

    Fix: Add a role contact (for example noc@ or peering@ an address you monitor) with visibility Public.
