I made this to scratch my own itch. When I get DDoS'd I can relieve the pressure very easily by blocking Cloudflare, ChinaNet, DigitalOcean, Linode, Hetzner and OVH.

And thus, ASN Tool was born.I am running it on a cheap DO box with OpenResty/Lua as the backend. It seems to handle about 500 requests/second, which I hope is good enough for the time being.After this
