If there is a way to query the server and for servers to test on I can build one out. I am not finding any documenation on querying one of these servers. Just requests to add such a feature. If you have info pleas update this issue.

Servers in factorio use a master server sort of method. That being said though, I've managed to capture what's sent back to a client upon entering the "Play on lan" menu ingame. Unfortunately I don't have enough knowledge within PHP or dealing with bytes, but I have figured out that 0090 2a is the max player count. I could be wrong, but I also think 0090 0d is the players online count.

Note that these bytes are from a server which has public visibility set to false along with lan visibility set to true. Only real changes are to the IP and whatever's in the first half of 0000. Sadly I have no friends so I can't really test on where the player list would be found. My guess would be after 00F0.

All that is sent to the server upon query seems to be a 0x10 byte.

Not sure if this helps, but here's the view from ingame. ingame

I could provide a pcap file if needed.

Unless there is a way to send a query packet to the server on demand similar to other protocols like Source and the old Gamespy protocols I will be unable to add support.

If you find some documentation on how to send a request to a server and have it respond with the server information please open this issue back up.
