What to fix
-
Warning
1 of 26 announced prefixes have no ROA (RPKI not found): 92.119.254.0/24.
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS51918 and a max length equal to the prefix length:
92.119.254.0/24 AS51918 max-length /24
