Dans la FAQ de spamhaus, je lis que sont pris en compte les netmask /64 et /32 mais ça ne parle pas des /128 (pour ovh ce sont des /128). Cela pourrait il influencer la donne ?
Why was this IP listed?
CSS lists both IPv4 addresses (/32) and IPv6 addresses (/64). CSS listings are influenced by:
- Email showing indications of unsolicited nature;
- Having poor list-hygiene;
- Sending out bad email due to a compromise, insecure installation or misconfigured server;
- Other indicators of low reputation or abuse.
CSS listings are based on a wide range of inputs and are always the result of multiple events and heuristics.
