What to fix
-
Warning
No abuse contact is published for AS9354.
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 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.
