Hello,
I would like to suggest following protocol to scan minecraft servers. It's dosn't need to have query-enabled on server and support more servers than query. In case that my (ip - randomcraft.ru) server cannot be correctly handled by query protocol.

Hi wasder,

Thanks for the suggestion.

I haven't heard of this ping request message until now. What range of Minecraft servers support this? Is this pre-1.0 only, or does it include the newer builds?

This protocol is VERY limited on data. Many of the features we offer on GT would not be usable with this protocol. We will consider your suggestion when planning updates to GT, although due to the limited data set, I don't think we will support this protocol.

Best regards.
