What to fix

  1. Warning

    No abuse contact is published for AS2528.

    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.

  2. Warning

    Fix: Try again in a minute.
