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
-
Problem
26 of 222 announced prefixes are RPKI invalid: 91.255.32.0/20, 94.160.0.0/17, 94.160.128.0/17, 94.161.0.0/17, 94.161.128.0/17 (+21).
A ROA covers them but does not allow this origin or prefix length, so networks that filter (most large ones do) drop these routes.
Fix: Fix the ROAs (origin AS and max length) at your RIR, or stop announcing the routes.
-
Warning
74 of 222 announced prefixes have no IRR route object: 151.59.32.0/21, 2.157.192.0/18, 2.159.128.0/18, 5.77.64.0/22, 151.58.160.0/20 (+69).
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 AS1267 in your RIR’s IRR database (or RADB).
route: 151.59.32.0/21 origin: AS1267 route: 2.157.192.0/18 origin: AS1267 route: 2.159.128.0/18 origin: AS1267

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.
