Is there anywhere that provides a list of CIDR ranges for web hosting providers, data centers, cloud computing services etc.? It could be free or commercial.

I get a lot of web scraping from these IPs, and would like to block as many as possible.

    AWS publishes their IP address ranges regularly. docs.aws.amazon.com/general/latest/gr/aws-ip-ranges.html May 13 at 10:26

  • Great way to be deindexed by search engines... May 13 at 17:01
  • @BrunoRohée - Search engines use their own ranges. I would like to block commercial servers and cloud hosting platforms that are rented out and often used fro scraping and abuse. So far I just went through the most common ASN names in my logs, blocked the ones that are not residential ISP blocks or other clean blocks. 18 hours ago
