I noticed a suggested edit that added hosting to a question with minecraft-server. Since Minecraft has been rather extremely updated in this regard, I think it warrants a meta discussion. I'm not hugely up-to-date on current Minecraft, so if anything is incorrect feel free to fix it.
In ye olden days, when Minecraft was PC-only, there was a separate application used as a server. This is still true, but I believe it is only for the java edition. See here
Now that most versions use the bedrock edition, the server functionality it built in to the game. Combined with additional confusion with the introduction of Realms, tagging questions about hosting Minecraft servers might need clarification.
The hosting snippet reads:
If your question is about a specific game's dedicated server software, please use the tag for that game's software instead
and the wiki states:
If your question is about a specific game's dedicated server, please use the tag for that game instead, For example, use minecraft-server for Minecraft dedicated server questions.
