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.

Warning
2 of 5 announced prefixes have no ROA (RPKI not found): 2a10:9903:201::/48, 2001:678:7ec::/48.
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS50917 and a max length equal to the prefix length:
2a10:9903:201::/48 AS50917 max-length /48 2001:678:7ec::/48 AS50917 max-length /48
