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 72 announced prefixes have no ROA (RPKI not found): 41.74.240.0/20, 41.74.243.0/24, 41.74.252.0/24, 41.74.254.0/24, 41.223.156.0/22 (+5).
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS11259 and a max length equal to the prefix length:
41.74.240.0/20 AS11259 max-length /20 41.74.243.0/24 AS11259 max-length /24 41.74.252.0/24 AS11259 max-length /24 41.74.254.0/24 AS11259 max-length /24 41.223.156.0/22 AS11259 max-length /22 197.216.0.0/15 AS11259 max-length /15 197.216.2.0/24 AS11259 max-length /24 197.216.6.0/24 AS11259 max-length /24 197.216.7.0/24 AS11259 max-length /24 197.216.8.0/24 AS11259 max-length /24

Warning
65 of 72 announced prefixes have no IRR route object: 197.216.128.0/24, 197.216.53.0/24, 197.216.8.0/24, 197.216.86.0/24, 197.217.82.0/23 (+60).
Many networks build their prefix filters from IRR data; without route objects some of them drop the routes.
Fix: Create route (IPv4) and route6 (IPv6) objects with origin AS11259 in your RIR’s IRR database (or RADB).
route: 197.216.128.0/24 origin: AS11259 route: 197.216.53.0/24 origin: AS11259 route: 197.216.8.0/24 origin: AS11259

Warning
No abuse contact is published for AS11259.
Other networks send reports of spam, attacks and hacked machines to the abuse contact. Without one, reports go nowhere and blocklists may list the whole range.
Fix: Add an abuse contact to the registration: abuse-c in the RIPE database, an Abuse POC at ARIN, an abuse mailbox (IRT) at APNIC, AFRINIC or LACNIC.
