What to fix

  1. Warning

    1 of 3 announced prefixes have no ROA (RPKI not found): 38.115.62.0/24.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS34 and a max length equal to the prefix length:

    38.115.62.0/24 AS34 max-length /24

    Open in RPKI / ROA validator Guide

  2. Warning

    PeeringDB did not answer: HTTP 404

    Fix: Try again in a minute.
