How to report malicious IP

So I was disassembling a malware and found out that it contacts 5 ip addresses, and one of them had a domain .ip.gl.ply.gg
I am 100% sure this program/ip is malicious, so how can I report it?

Your best bet is to find some staff on the Discord server https://discord.gg/AXAbujx.
