What to fix

  1. Warning

    10 of 10 announced prefixes have no ROA (RPKI not found): 38.252.80.0/24, 45.229.156.0/22, 45.229.156.0/23, 45.229.158.0/23, 187.17.132.0/22 (+5).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS267120 and a max length equal to the prefix length:

    38.252.80.0/24 AS267120 max-length /24
45.229.156.0/22 AS267120 max-length /22
