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
10 of 772 announced prefixes have no ROA (RPKI not found): 63.160.0.0/24, 63.160.4.0/23, 63.160.32.0/21, 63.160.224.0/19, 63.161.16.0/20 (+5).
Without a ROA, networks cannot tell your routes from a hijack.
Fix: Create a ROA for each at your RIR portal, with origin AS4637 and a max length equal to the prefix length:
63.160.0.0/24 AS4637 max-length /24 63.160.4.0/23 AS4637 max-length /23 63.160.32.0/21 AS4637 max-length /21 63.160.224.0/19 AS4637 max-length /19 63.161.16.0/20 AS4637 max-length /20 63.161.224.0/19 AS4637 max-length /19 63.164.160.0/19 AS4637 max-length /19 63.172.128.0/19 AS4637 max-length /19 63.175.32.0/19 AS4637 max-length /19 65.160.160.0/19 AS4637 max-length /19

Warning
86 of 772 announced prefixes have no IRR route object: 217.151.39.0/24, 217.151.40.0/23, 64.145.224.0/19, 65.160.160.0/19, 207.15.96.0/19 (+81).
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 AS4637 in your RIR’s IRR database (or RADB).
route: 217.151.39.0/24 origin: AS4637 route: 217.151.40.0/23 origin: AS4637 route: 64.145.224.0/19 origin: AS4637

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.
