Thanks Andem. I didn't have a couple of the OVH server ranges.
Some of the OVH ranges however (example the DSL ranges or the SMTP company) I don't consider a categorical threat. Also, just because OVH (or anyone) manages/owns a range, that's not enough for me to block it, unless the range is specifically used for web servers, colos, data centers, etc. If they are leasing the range to a private company (that is not a host, colo, data center, etc) I need to see bad behavior from that company before I block the range.
Had all of the Hetzner.
