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
10 of 1036 announced prefixes have no ROA (RPKI not found): 103.105.28.0/24, 103.105.29.0/24, 103.105.30.0/24, 103.105.31.0/24, 103.105.32.0/24 (+5).
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS4761 and a max length equal to the prefix length:
103.105.28.0/24 AS4761 max-length /24 103.105.29.0/24 AS4761 max-length /24 103.105.30.0/24 AS4761 max-length /24 103.105.31.0/24 AS4761 max-length /24 103.105.32.0/24 AS4761 max-length /24 103.105.33.0/24 AS4761 max-length /24 103.105.34.0/24 AS4761 max-length /24 103.105.35.0/24 AS4761 max-length /24 103.108.28.0/24 AS4761 max-length /24 103.108.30.0/24 AS4761 max-length /24

Warning
63 of 1036 announced prefixes have no IRR route object: 2400:8b00:1610::/44, 2400:8b00:21a0::/44, 2400:8b00:2290::/44, 2400:8b00:600::/44, 2400:8b00:700::/44 (+58).
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 AS4761 in your RIR’s IRR database (or RADB).
route6: 2400:8b00:1610::/44 origin: AS4761 route6: 2400:8b00:21a0::/44 origin: AS4761 route6: 2400:8b00:2290::/44 origin: AS4761

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.
