Best servers for multiplayer?

Depends on the kind of gamemode you like. Hypixel has pretty much everything, but there are a lot of cheaters in the game that don't get banned immediately. If you're into UHC or PvP type games, then you might be interested in Invaded Lands, Mineman Club, Velt PvP, Arcane, Faithful, Arctic UHC, etc.

Just google the name of the server and the server IP should pop up.

The best minecraft role-play server is SP ('server pyaterki'). There you can meet best minecraft community ever.
There is one minus - you will need to buy whitelist to get to the server

Mineplex, Hypixel, skycraft, there are a ton of good servers in minecraft

mccentral.org is good, hypixel.net is good, jartexnetwork.com is good, vanitymc.co is also good

I don't really know but this website has servers I like https://www.pcgamesn.com/minecraft/15-be...ft-servers

If you're searching for a big one then its Hypixel.net but you can try to find smaller servers from lists.

example: https://minecraft-server-list.com/

A single game is better than a multi-player. Try it, you will be delayed
