Network report
Who holds an IP address, prefix or AS number, how it is routed (origin AS, RPKI, IRR), its reverse DNS, blocklist listings and PeeringDB record, with what to fix first.
Checking routing, RPKI, reverse DNS, blocklists and the registry. This usually takes 3 to 10 seconds.

What to fix
-
Warning
10 of 99 announced prefixes have no ROA (RPKI not found): 78.138.62.0/24, 91.190.240.0/21, 136.243.0.0/16, 138.201.0.0/16, 144.76.0.0/16 (+5).
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS24940 and a max length equal to the prefix length:
78.138.62.0/24 AS24940 max-length /24 91.190.240.0/21 AS24940 max-length /21 136.243.0.0/16 AS24940 max-length /16 138.201.0.0/16 AS24940 max-length /16 144.76.0.0/16 AS24940 max-length /16 148.251.0.0/16 AS24940 max-length /16 149.245.242.0/24 AS24940 max-length /24 171.25.225.0/24 AS24940 max-length /24 185.50.120.0/23 AS24940 max-length /23 185.107.52.0/22 AS24940 max-length /22

Warning
No public NOC, policy or technical contact.
Other networks use these addresses to set up peering and to reach you during an incident.
Fix: Add a role contact (for example noc@ or peering@ an address you monitor) with visibility Public.
