Use these official addresses from the UnstableSMP Minelist listing:

• Java: unstablenetwork.xyz on port 25566

Copy buttons also appear in the sidebar. Bookmark this page so friends always get the current IP if the hostname ever changes.

Last ping reported software/version string: Paper 1.21.10. A version mismatch is one of the most common reasons a correct IP still fails to connect.

UnstableSMP is free to join from this Minecraft server list. You need a legitimate Minecraft Java account; Minelist does not charge you to connect.

If the server later sells optional ranks, those would be handled on their own site or Discord — not through a Minelist fee.

Yes — combat is part of how UnstableSMP is categorized (Survival), with related tags like pvp, smp, bedrock, hardcore.

That usually means PvP exists somewhere on the network (war zones, arenas, or open world). Always read spawn/safe-zone rules on this page or in Discord before fighting — many servers punish combat logging or spawn camping.

Our last successful ping for UnstableSMP reported version Paper 1.21.10. That string comes from the live server, so it is the most reliable clue when Multiplayer says “outdated client” or “outdated server”.

The owner also listed these supported clients: 1-21. Multi-version networks (ViaVersion / protocol support) can accept a range such as 1.20–1.21 even when the ping string shows one build.
