What to fix

  1. Warning

    1 of 3 announced prefixes have no ROA (RPKI not found): 150.254.0.0/16.

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

    Fix: Create a ROA for each at your RIR portal, with origin AS9112 and a max length equal to the prefix length:

    150.254.0.0/16 AS9112 max-length /16

    Open in RPKI / ROA validator Guide

  2. Warning

    No IRR as-set is listed.

    Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.

    Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
