What to fix

  1. Warning

    1 of 1 announced prefixes have no ROA (RPKI not found): 2804:93a0::/32.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS274790 and a max length equal to the prefix length:

    2804:93a0::/32 AS274790 max-length /32

    Open in RPKI / ROA validator Guide

  2. Warning

    PeeringDB did not answer: HTTP 404

    Fix: Try again in a minute.
