Minecraft Servers by Country

We resolve the address to the IP it actually points at, follow any SRV record first, and look that IP up in a country database. Nobody types their country in, so nothing here is self-reported.

The country is where the machine answering the address sits, not where the owner does. A German owner renting a box in Finland shows as Finland, and that is the number that matters for your ping.

Large networks sit behind proxy and DDoS-protection services, and those front-ends advertise their own IPs. The country then reflects the protection provider's nearest edge rather than the game server behind it.

Yes, for anything with timing in it. Latency is dominated by physical distance, so a server one country away typically answers in tens of milliseconds while one across an ocean takes hundreds.
