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 22 announced prefixes have no ROA (RPKI not found): 24.137.8.0/24, 66.59.96.0/24, 66.59.97.0/24, 66.59.98.0/24, 66.59.102.0/24 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS11590 and a max length equal to the prefix length:

    24.137.8.0/24 AS11590 max-length /24
66.59.96.0/24 AS11590 max-length /24
66.59.97.0/24 AS11590 max-length /24
66.59.98.0/24 AS11590 max-length /24
66.59.102.0/24 AS11590 max-length /24
66.59.104.0/24 AS11590 max-length /24
66.59.107.0/24 AS11590 max-length /24
66.59.108.0/24 AS11590 max-length /24
66.59.109.0/24 AS11590 max-length /24
66.59.110.0/24 AS11590 max-length /24

  3. Warning

    9 of 22 announced prefixes have no IRR route object: 24.137.8.0/24, 66.59.122.0/24, 66.59.123.0/24, 66.59.117.0/24, 66.59.114.0/24 (+4).

    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 AS11590 in your RIR’s IRR database (or RADB).
