What to fix

  1. Warning

    7 of 7 announced prefixes have no ROA (RPKI not found): 79.171.104.0/21, 213.134.32.0/19, 213.134.32.0/21, 213.134.40.0/21, 213.134.48.0/21 (+2).

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

    Fix: Create a ROA for each at your RIR portal, with origin AS15919 and a max length equal to the prefix length:

    79.171.104.0/21 AS15919 max-length /21
213.134.32.0/19 AS15919 max-length /19
213.134.32.0/21 AS15919 max-length /21
213.134.40.0/21 AS15919 max-length /21
213.134.48.0/21 AS15919 max-length /21
217.75.224.0/19 AS15919 max-length /19
