What to fix

  1. 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.

    Open in ASN & BGP prefix lookup

  2. Warning

    10 of 13 announced prefixes have no ROA (RPKI not found): 38.46.232.0/24, 38.46.233.0/24, 38.46.234.0/24, 38.46.235.0/24, 38.188.207.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS142307 and a max length equal to the prefix length:

    38.46.232.0/24 AS142307 max-length /24
38.46.233.0/24 AS142307 max-length /24
38.46.234.0/24 AS142307 max-length /24
38.46.235.0/24 AS142307 max-length /24
38.188.207.0/24 AS142307 max-length /24
38.191.164.0/23 AS142307 max-length /23
38.191.164.0/24 AS142307 max-length /24
38.191.165.0/24 AS142307 max-length /24

38.226.46.0/24 AS142307 max-length /24

  3. Warning

    6 of 13 announced prefixes have no IRR route object: 38.226.46.0/24, 38.191.164.0/23, 38.188.207.0/24, 38.226.45.0/24, 103.179.84.0/24 (+1).

    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 AS142307 in your RIR’s IRR database (or RADB).

    route: 38.226.46.0/24
origin: AS142307

route: 38.191.164.0/23
origin: AS142307

route: 38.188.207.0/24
origin: AS142307

  4. 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.
