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.

Warning
10 of 59 announced prefixes have no ROA (RPKI not found): 43.230.188.0/24, 43.230.189.0/24, 43.230.190.0/24, 43.230.191.0/24, 103.1.36.0/23 (+5).
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS64047 and a max length equal to the prefix length:
43.230.188.0/24 AS64047 max-length /24 43.230.189.0/24 AS64047 max-length /24 43.230.190.0/24 AS64047 max-length /24 43.230.191.0/24 AS64047 max-length /24 103.1.36.0/23 AS64047 max-length /23 103.1.36.0/24 AS64047 max-length /24 103.1.37.0/24 AS64047 max-length /24 103.1.38.0/24 AS64047 max-length /24 103.1.39.0/24 AS64047 max-length /24 103.25.252.0/24 AS64047 max-length /24

Warning
3 of 59 announced prefixes have no IRR route object: 2402:b780:55::/48, 2402:b780:53::/48, 2402:b780:54::/48.
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 AS64047 in your RIR’s IRR database (or RADB).
route6: 2402:b780:55::/48 origin: AS64047 route6: 2402:b780:53::/48 origin: AS64047 route6: 2402:b780:54::/48 origin: AS64047
