SMP stands for survival multiplayer, but on a server list it usually means something more specific: a small, long-running world with a community that knows each other, often whitelisted or application-only. Fewer plugins, fewer resets, and far more shared history than a public server accumulates.
These are the servers where spawn was built by players over several years, where somebody runs a shop because they felt like it rather than for profit, and where a griefing incident is a community event rather than a support ticket. The application exists to keep it that way, so expect a few questions on Discord and a day of waiting.
Check how long the world has run, how many people are online at your play time, and whether a map reset is planned. A good SMP is worth writing an application for, but a dead one is very dead — read a week of the Discord before you spend an evening on the form.
1.12.2 is still the default for modded, and here is why
Version 1.12 arrived in 2017 with concrete, glazed terracotta, parrots, the recipe book and advancements replacing the old achievement list. It is remembered for none of that. It is remembered because 1.13 followed it with the flattening, which removed numeric block IDs and rewrote how the game stores world data.
That break stranded an enormous amount of work. Forge mods written for 1.12.2 could not be ported cheaply, so the packs people had spent years assembling stayed where they were, and 1.12.2 became the most played modded version in the game's history. Large packs and their servers are still running on it today.
If you are joining a 1.12 server, expect Forge, expect a launcher profile pinned to 1.12.2, and expect an older feel: no netherite, no raids, no bees, and terrain that stops at Y=0. In exchange you get a mod ecosystem nothing since has quite matched for sheer size. The final patch landed in September 2017 and the version has not moved since, which is exactly why pack authors trust it — a modlist assembled today behaves the same as one assembled five years ago.
