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
4 of 21 announced prefixes have no IRR route object: 2401:7ec0:4000::/36, 2401:7ec0:2000::/36, 2401:7ec0:1000::/36, 2401:7ec0:3000::/36.
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 AS59127 in your RIR’s IRR database (or RADB).
route6: 2401:7ec0:4000::/36 origin: AS59127 route6: 2401:7ec0:2000::/36 origin: AS59127 route6: 2401:7ec0:1000::/36 origin: AS59127
-
Warning
No abuse contact is published for AS59127.
Other networks send reports of spam, attacks and hacked machines to the abuse contact. Without one, reports go nowhere and blocklists may list the whole range.
Fix: Add an abuse contact to the registration: abuse-c in the RIPE database, an Abuse POC at ARIN, an abuse mailbox (IRT) at APNIC, AFRINIC or LACNIC.
-
Warning
No IRR as-set is listed.
Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.
Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
