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 15 announced prefixes have no ROA (RPKI not found): 152.226.3.0/24, 152.226.32.0/20, 152.226.64.0/24, 152.226.73.0/24, 152.226.128.0/20 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS9292 and a max length equal to the prefix length:

    152.226.3.0/24 AS9292 max-length /24
152.226.32.0/20 AS9292 max-length /20
152.226.64.0/24 AS9292 max-length /24
152.226.73.0/24 AS9292 max-length /24
152.226.128.0/20 AS9292 max-length /20
152.226.152.0/21 AS9292 max-length /21
152.226.160.0/20 AS9292 max-length /20
152.226.184.0/24 AS9292 max-length /24
