I'm thinking that this might be a bot constantly attempting to connect to my server. However, my server's ping response is disabled and I've got its true address hidden behind a DNS. An IP phisher shouldn't be able to find my host computer, let alone know that it's hosting a Minecraft server. Is it possible that this is a Forge problem or do I need to start taking steps to change my address and implement greater protection?
