I have some bot problem, i found their ASN and it comes from web hosting providers. Not ISP's. For example:

  • Hetzner: AS24940
  • Digital Ocean: AS14061
  • AMAZON-AES: AS14618

Is it safe to ban entire ASN's if they belong to hosting providers? There's like 2 million IP's in these. I wouldn't like to ban legitimate visitors.

Yes.

These are not users. Assigned IP addresses are assigned in blocks that are either subscriber, such as DSL customers, or non-subscriber, such as web hosting. It is always safe to block non-subscriber blocks short of a search engine or other service you may actually want. For example, I routinely block traffic from link bots and site performance sites by blocking the entire assigned block(s) as well as web hosts that have a problem with hacked servers or host spam bots, scrapers, etc.
