That's harder to set up, and also unfair to people who have an odd IP address.

It's easier and better to just block 0.0.0.0/1 half of the time, and 128.0.0.0/1 for the other half of the time. Switch every day at noon.

Bot traffic will be cut by 50%, and humans are all treated equally! It's a total win!

And blocking ipv6 addresses isn't unfair to people who have an ipv6 address?

Yeah, I suppose you're right.

Just block it all.
