DayZ server list crawler

This address belongs to a crawler run by Darkzone. It keeps a list of DayZ servers up to date for a server browser, by asking each server about itself the same way the game's own server browser does.

What it sends

• Steam server queries (A2S_INFO and A2S_RULES) to a server's query port, for its name, player count, settings and mods.
• Servers with players: once a minute. Empty servers: every 5 minutes, and their mods every 10.
• A server it hasn't seen before: every 10 minutes until it has been checked.

It never connects to a server's game port, sends nothing else, and isn't a scan or an attack.

Being left out

To have a server left out of the list and no longer queried, write to crawler@darkzone.dev with its address and query port.
