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
No IPv6 prefixes announced.
Networks without IPv6 force their users through NAT64 or leave them unreachable from IPv6-only networks.
Fix: Get an IPv6 allocation from your RIR (usually free with your IPv4 membership) and announce it.
-
Warning
10 of 27 announced prefixes have no ROA (RPKI not found): 210.102.96.0/24, 210.102.97.0/24, 210.102.98.0/24, 210.102.99.0/24, 210.102.100.0/24 (+5).
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS9455 and a max length equal to the prefix length:
210.102.96.0/24 AS9455 max-length /24 210.102.97.0/24 AS9455 max-length /24 210.102.98.0/24 AS9455 max-length /24 210.102.99.0/24 AS9455 max-length /24 210.102.100.0/24 AS9455 max-length /24 210.102.101.0/24 AS9455 max-length /24 210.102.102.0/24 AS9455 max-length /24 210.102.103.0/24 AS9455 max-length /24 210.102.104.0/24 AS9455 max-length /24 210.102.105.0/24 AS9455 max-length /24
